Abstract
Aiming at the status quo of the loss of arable land resources and non-agricultural problems,taking the cultivated land resources of Zhongxiang City in 2005 and 2015 as an example,we studied the spatial and temporal variation of cultivated land ecological value by using the alternative market method.The results showed that:Among the ecological value of cultivated land in Zhongxiang City, the value of regulating the atmosphere is 80.27%,the value of soil conservation is 13.27%,the proportion of other types of ecological value is 6.46%.From 2005 to 2015,the ecological value of cultivated land in Zhongxiang City developed along the northwest direction,and its distribution was more and more dispersed. The average center of the farmland was about 160 m in the northwest direction,and the moving direction was consistent with the long axis of the trend ellipse.According to the analysis, the following conclusions were obtained:It ramained differences among different types of ecological valued land;the ecological value of different types in Zhongxiang presented different changing trends,but the change range was small generally;with the further development of urban-rural integration,the ecological value of arable land was more and more dispersed in space.关键词
