摘要：
Urbanization-induced land use transitions (LUTs) result in a decline in ecosystem services, which has implications for regional ecological security. In order to explore the relationship between ecosystem services and land use transition, this paper utilizes the InVEST model, a geographically weighted regression (GWR) model, to examine the impact of land use transition on ecosystem services in the Dongting Lake area (DLA). The results showed that 1) with the change in urbanization development, the average values of land use transition intensity (LUI) in 2000, 2010, and 2020 are 237.99, 235.82, and 238.92, respectively. Land use dynamics (LUD) show a tendency to increase and then decrease, with average values of 5.58 and 5.62 for the periods 2000-2010 and 2010-2020, respectively, and the transformation of land use shows obvious spatio-temporal heterogeneity. 2) Habitat quality and carbon sequestration showed a downward trend. In contrast, food supply followed an upward trend; soil conservation (SC) and water yield (WY) services initially increased and decreased later. The overall spatial changes in habitat quality and carbon sequestration appear to be insignificant. Food supply shows significant differences in the plains compared to other areas, while soil conservation and water yield service show significant changes in places other than the DLA. 3) From 2000 to 2020, land use transition dynamics, population density, GDP density, night lighting, and transition intensity had mainly negative effects on ecosystem services. Only the Normalized Vegetation Index (NDVI) showed a positive effect on ecosystem services. The results of the research will provide valuable references for the development and implementation of spatial ecological restoration planning and land use policies in the national territory.

摘要：
<jats:p><jats:bold>Introduction:</jats:bold> The construction of digital governance of national land space depends greatly on the development of a digital model for robust control of water and ecological space. However, how changes to the urban-water coupling relationships affect the resilience control of water ecological space is rarely reported.</jats:p><jats:p><jats:bold>Methods:</jats:bold> The evolution characteristics of urban and water space in the study area from 2000 to 2020 and the correlation between them are analyzed based on the grid analysis using InVEST and Moran’I methods. Based on the theory of human-environment interaction territorial system to provide a theoretical framework to explain the urban and water space. We used digital to construct an resilience control framework in the Dongting Lake area based on the correlation between the urban and water space.</jats:p><jats:p><jats:bold>Results:</jats:bold> The results show that: 1) From 2000 to 2020, the geographical evolution of towns and cities in the research area displayed obvious spatial variation in intensity, indicating a process of expansion and change. The regional and temporal fluctuations of the water conservation function are significant. The mountainous areas in the east, south, and northwest are where the high values of the water conservation function are primarily found. These regions have more vegetation, which increases the water conservation function. 2) According to the results of local binary spatial autocorrelation analysis, it can be seen that from 2000 to 2020, the high-high agglomeration of town space and water-related is mainly distributed in Linxiang City, Yueyang County, Miluo City, Li County, and Yiyang City, and the low-low agglomeration is mainly distributed in Dongting Lake, Datong Lake, and along the Yangtze River. 3) Based on how urban spatial evolution affects water ecological space, we construct a theoretical framework of urban-water coupling and establish a digital model of water ecological space resilience control in the Dongting Lake area from four perspectives: threshold, visualization, dynamics, and intelligence.</jats:p>

摘要：
The territorial spatial planning in the new era strengthens the control of different functional spaces and emphasizes integrated and coordinated development of each functional space. Therefore, it is important to monitor the “structure-function” characteristics of water-ecological space based on the context of territorial spatial planning and develop a management and control framework. Based on land use and social statistics, and with the help of ArcGIS analysis, this paper examined the structure and function of the water-ecological space in the Dongting Lake study for 2010, 2015, and 2020, generating a control framework and proposing key initiatives. The main results are as follows: 1) The overall scale of the water ecological space in the Dongting Lake study is over 7,300km2. Water bodies had the largest share, followed by coastal terrestrial areas, while the land-water ecotone was the smallest. There was a small decrease in the water ecological space during the study period. Yueyang had the largest overall scale of water ecological space, while Linli had the smallest. 2) The comprehensive function of water ecological space in the Dongting Lake study was about 0.4000, increasing somewhat during the study period. Among the units, the comprehensive function value was highest in Yuanjiang City, while Jincheng City had the lowest. 3) From the structural elements of water ecological space, scientific planning of functional zoning of water ecological space should be carried out and combined with the delineation of “three zones and three lines.” Key initiatives such as multi-scale and multi-level planning and control, use control and access restrictions, determination of water ecological space ownership, pollution control and accountability, and comprehensive water ecological treatment and restoration should be promoted.

DLB;Ecological degradation;Ecological service function;Geographic detector;Landscape pattern index
摘要：
Understanding the spatio-temporal characteristics of ecological degradation and its mechanism is the key to implementing national land space ecological restoration. Currently, there is a lack of knowledge about identifying ecologically degraded areas from a structure–function angle. This paper used the Dongting Lake Basin (DLB) as the research area, with the landscape pattern index and InVest model utilized to analyze the landscape distribution characteristics and ecosystem service functions in 2000 and 2018. Based on this, a fuzzy inference approach and geographic detectors were used to explore the characteristics and driving mechanism of ecological degradation in the DLB from 2000 to 2018. The results found are the following: (1) The overall landscape of the DLB was fragmented, the landscape shape tended to be complex, the degree of aggregation declined, and the landscape types were more discrete than before. In terms of the landscape-level index, the overall indicators of the landscape pattern in the DLB showed little change from 2000 to 2018, and the overall landscape pattern change was reasonably stable. (2) The three ecological services exhibited prominent spatial distribution features during the study period. In particular, food supply services showed a steady upward trend, while habitat quality and carbon storage services generally declined. (3) The ecological degradation in the DLB demonstrated striking spatial and temporal differences during the study period, and the ecological situation improved. The ecological degradation areas were mainly distributed in urban areas with denser populations and a higher level of urbanization, while the ecological restoration areas were mainly in the mountainous and hilly areas far away from the urban centers. (4) Among the influential factors, the production potential of urban land and farmland is the main factor that affects the ecological environment degradation and spatial distribution difference in the DLB. The interactive detection results indicate that the driving mechanism exhibits a two-factor enhancement or nonlinear increase. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

摘要：
Understanding the pattern and quality of construction land expansion in urban agglomerations is important for new urbanization and high-quality development of land spaces. Taking urban agglomeration in the middle reaches of the Yangtze River as the research object, this study analyzes the spatio-temporal pattern and quality level of construction land expansion at various scales using remote sensing images, the expansion intensity index, the coordination degree model, and the Tapio elastic decoupling model. The results show that from 2000 to 2020, (1) the construction land scale of urban agglomeration in the study area had expanded, with significant stage characteristics and spatial differentiation patterns. (2) The overall relationship between the construction land and the population in urban agglomerations was found to be uncoordinated, but the coordination degree had been improved. The optimization of human–land coordination was faster at the metropolitan scale than at the overall level and the sub-urban agglomerations. (3) The decoupling relationship between the overall construction land and the economy in urban agglomerations was weak and had improved. The coupling/decoupling relationship was found to be better at the metropolitan scale than at the overall level and sub-urban agglomerations. Copyright © 2022 Ning, Ouyang and Liu.

摘要：
探讨土地利用变化与景观格局之间的关系可以为区域生态管理提供依据。以洞庭湖地区为研究对象,以该地区2000、2005、2010和2015年4个时期的遥感影像为基础,综合运用地理信息系统(GIS)、景观格局分析等方法,定量描述该地区的土地利用和景观格局的时空演变规律,并利用OLS回归分析土地利用变化与景观格局之间的关系。结果表明:①开发区和新城区建设等经济社会发展条件下土地利用发生显著变化,以耕地和林地转化为建设用地为主要特征,其中,建设用地和未利用地面积持续增长,耕地、林地、草地和水域面积明显减少。②景观水平层面下洞庭湖地区景观格局的破碎程度上升和聚集程度下降,其中,林地和草地的破碎化程度上升,林地的破碎化程度上升趋势有所缓解。并在空间尺度上表现建成区范围内景观指数变化显著。③类型水平层面下,其景观格局的集聚程度呈现上升趋势。景观格局变化与耕地、林地、未利用地和建设用地的变化具有较强的关系,建设用地扩张增加了整个景观格局的异质性和破碎性。同时,提出相应的对策措施,以期为洞庭湖地区更好地协调优化空间开发与景观格局之间的关系。

摘要：
Fe–Mn binary oxide nanoparticles (FMBON) were reported to be high performance as adsorbent for pollutants removal from aqueous solution. However, there are still limitations in practice application due to the FMBON tend to aggregate into the micro millimeter level. In order to avoid the agglomeration of nanoparticles, this work synthesized the stabilized Fe–Mn binary oxide nanoparticles (CMC-FMBON) by using water-soluble carboxymethyl celluloses (CMC) as the stabilizer. The characteristics of CMC-FMBON and FMBON were measured by using Transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and Zeta potential. This work systematically investigated the adsorption capacity of CMC-FMBON for 17β-estradiol (E2) and the influences of external environmental factors on E2 removal. The results indicated that CMC-FMBON had much smaller particles, wider dispersion and larger surface area than the FMBON. CMC-FMBON showed better adsorption performance for E2 than FMBON with the maximum adsorption capacity of CMC-FMBON and FMBON were 124.10 and 98.14 mg/g at 298 K, respectively. The experimental data can be well fitted by the model of pseudo-second-order and Langmuir model. The E2 removal by CMC-FMBON was obviously dependent on pH with the maximum adsorption occurring when the pH was acidic. The removal capacity of CMC-FMBON increased when enhancing ionic strength in solution. Background electrolytes promoted slightly E2 adsorption process whereas the presence of humic acid inhibited the E2 removal. π-π interactions, hydrogen bonds, and oxidation might be responsible for E2 removal. This research suggested that the CMC-FMBON has been considered to be a cost-efficient adsorbent for removing E2 from water. © 2018 by the authors. Licensee MDPI, Basel, Switzerland.

城市群是新型城镇化发展的主要载体,也是人地关系矛盾凸显的地方之一.在界定生态文明内涵的基础上,构建符合城市群生态文明建设评价的综合指标体系,我们采用熵值法和空间分析法对长江中游城市群的生态文明建设水平和空间差异分析发现:28个地级市的生态文明建设水平有着明显差异,生态文明建设波动呈现"U"形变化;三大子城市群之间生态文明呈现出不同的建设水平,环长株潭城市群生态文明建设水平最高,其次是环鄱阳湖城市群,而武汉城市圈位于末尾;各子城市群内的城市生态文明建设水平差异化明显.通过区域协作和产业结构调整等措施是提高长江中游城市群生态文明建设水平的重要因素.

摘要：
益沅桃城镇群的建设是提升益阳市的区域竞争力,形成湘北地区新的增长极的重要举措。以SPSS软件的主成分分析法测度益沅桃城镇群各部分的经济发展实力,并结合空间相互作用引力模型测算各城镇的经济联系强度及对中心城区的隶属度,以此定量分析益沅桃城镇群的基本经济情况。结果表明:益阳市区在城镇群中处于绝对的经济中心地位,沅江市、桃江县与益阳市区的经济差距较大,益阳市区的辐射带动作用有待提高;益阳市在区内的引力强度最高,桃江县因距离的邻近效应,引力强度和隶属度排在第二,沅江市因区位和经济独立性排在第三。

摘要：
产城融合是推动长株潭城市群产业升级的主要动力之一.基于学者们对于产城融合研究的基础上,构建了符合长株潭城市群产城融合评价的指标体系,并运用主成分分析法对2016年城市群的26个产业园区进行产城融合的综合考量.研究表明:城市群产业园区的产城融合发展整体水平不高,将产业园区产城融合发展水平分成3类,处于第1类的产业园区只有3个,表现出产城融合发展不均衡.同时,根据产城融合方面的问题,从产业园区的产业升级和城市化的方面提出了相关的政策建议.

摘要：
以湖南省14个地级市为研究单元,运用变异系数和空间自相关法等方法,实证测算了2005—2014年湖南省各地级市外向型经济的区域差异特征。结果表明:①出口贸易区域内呈现由分散向集中转变的态势,而实际利用FDI在各市之间呈扩散发展趋势;②湖南省外向型经济区域存在显著差异,长株潭城市群为主要开放阵地;③不同区域之间的对外开放度差距逐年缩小但依旧较大,湖南省的开放度水平整体得到了提高;④湖南省各地级市的对外开放度存在较强空间自相关性,出现空间集聚的情况。
