Performance Evaluation of Last 10-year Landuse Change in Chongqing City
摘要
Abstract
We analyzed land use changes of Chongqing City during the last 10 years,and then built a landuse evaluation system,considering both regional geographic characteristics and the requirement of quantitative evaluation.The results showed that the area of farmland decline sharply between 1999—2008,accounting for a net decrease of 293 679.7 hm2.Meanwhile,the area construction land increased substantially by a total of 74 334.1 hm2.Both the structure of landuse configuration and the degree of land utilization decreased,from 0.713 2 and 0.114 3 in 1999 to 0.294 2 and 0.038 7 in 2008,respectively.Land use conflicts highlighted the low intensification degree of landuse in the study area.Land use efficiency and utilization benefit increased significantly from 0.065 5 and 0.046 7 in 1999 to 0.447 2 and 0.301 1 in 2008,respectively.However,the overall efficiency is still relatively low,indicating that the land productivity can still be improved potentially.Landuse performance value was still relativity low,but its trend was keeping increasing steadly,similar the changes of social economical development and natural environmental condition.Chongqing City is moving towards in a development direction of reasonable and sustainable land use.关键词
