摘要
根据河南境内南水北调中线沿线地区的土地利用数据,分析了土地利用变化的空间特征,并在县域尺度上分析了不同时期土地利用的生态环境效应。结果表明,近年来该区域耕地向建设用地的转移面积较多,但土地利用的整体格局并未发生显著变化,而整个区域内土地利用变化强度的空间分布极不均匀。中线工程施工以来,沿线地区生态环境状况总体上有所改善。
Based on the land use data in the Middle Route of South-to-North Water Transfer Project（SNWTP） in Henan Prov ince, the spatial characteristics of land use change were analyzed, and the eco-environmental effects of land use in different periods at the county scale were investigated. The results indicated that a large area of cultivated land has become the construction land in recent years, but the overall pattern of land use has not changed significantly. Over the whole area, the spatial distribution of land use change intensity is extremely uneven. In addition, since the construction of Middle Route of SNWTP, the ecological environment has improved in general.
