摘要
以位于中原城市群的济源市为研究区,综合运用遥感、GIS空间分析和数理统计方法,结合区域生态环境指数以及生态环境状况指数,定量分析了济源市2000-2012年土地利用与生态环境状况的相关性,并综合评价了土地利用变化的生态环境效应.结果表明:济源市土地利用变化剧烈,其中耕地面积减少了115.38km2,建设用地面积增加了88.67km2;与此相应,2000、2006、2012年济源市区域生态环境指数及生态环境状况指数均呈现上升趋势,说明在土地利用变化影响下的生态环境状况在不断改善.土地利用格局变化中,林地、草地、水域面积增长是促进环境改善的主要原因,而因经济发展引起的城市建设用地范围的扩张、耕地的开垦和工业的发展等因素则对环境改善具有抑制作用.
Jiyuan City,located in Zhongyuan urban agglomeration,is taken as the study area in this paper.Combining with regional ecological environment index and the index of ecological and environmental conditions,remote sensing,GIS spatial analysis and mathematical statistics methods were all used to quantitative analysis of the correlation between land use and ecological environment in 2000- 2012,and the ecological effects from the change of land use was evaluated. The results are as follows: the use of land changed greatly in Jiyuan city,the area of cropland reduced 115. 38km^2,however the area of construction land increased 88. 67km^2. Accordingly the index of regional ecological environment and ecological conditions showed an upward trend in 2000,2006 and 2012. It indicats that the ecological environment conditions were improving. In the change of land use pattern,the growth of woodland,grassland,water area were the main reason for the improvement of environment,and some factors had prohibitive effect on the improvement of environment,such as the expansion of the urban construction land caused by the economic development,the reclamation of cropland,and the development of industry.
