土地利用过程中会产生期望和非期望产出,针对以往土地利用结构评价中忽略环境产生的非期望产出而影响土地利用结构效率真实性问题,以大都市城郊的上海青浦区为例,宏观上,运用信息熵模型对该区2005~2014年土地利用结构有序性进行评价;微观上,运用非期望产出模型测算青浦区研究期间土地利用结构效率,为寻求区域土地利用结构效率损失的原因及改善途径提供参考。结果表明:(1)2005~2014年青浦区土地利用结构信息熵值时序上呈现“M”形变化趋势,空间上由中部向东西两翼递减;(2)2005~2014年青浦区土地利用结构效率变化趋势在时间序列上呈现“W”形变化趋势,空间上由中部的中心城区向东西两翼递减格局;(...

Land using procession will produce the expected and unexpected output. In the past, evaluation of land use structure ignored the unexpected output which was produced by environment. In this paper, we used the information entropy model to evaluate the land use structure in Qingpu District of Shanghai city during 2005–2014, and used the SBMUndesirable model to evaluate the land use structure efficiency in this area. On the basis of that, we try to find the reasons for the loss of regional land use structure efficiency and the improving ways. The...
