为明确洞庭湖区东方田鼠Microtus fortis肥满度的时空特征及其与东方田鼠常用预警生态因子的关系,采用夹日法对洞庭湖7个调查区域不同生境的东方田鼠进行调查分析;收集洞庭湖区降水、温度、归一化植被指数(NDVI)等环境因子数据,分析不同性别东方田鼠肥满度与降水、温度、NDVI的关系.结果表明:1)不同性别东方田鼠肥满度时空特征较一致,春季和冬季不同生境雌雄东方田鼠的差异有高度统计学意义;在洲滩芦苇生境,雄雌东方田鼠在各季节间的差异有高度统计学意义;在洲滩苔草+芦苇+杨树生境,雄性肥满度各季节间的差异有统计学意义.2)雌性肥满度与季平均降水量呈显著正相关,雄性肥满度与季平均降水量无显...

The response mechanism of animals against environment pressure may be different between sexes.Relative fatness is a convenient index always used to indicate survive quality.Rainfall,temperature and normalized difference vegetation index(NDVI)are normally considered as environmental forecast factors.In order to understand the characteristic of relative fatness of Microtus fortis population and the relationship between relative fatness and environmental forecast factors,a population survey at 7 survey sites was implemented in Dongting Lake wetland.The habitat type was different for all the surve...
