摘要:
在RS和GIS技术支持下，利用马尔科夫转移矩阵和土地利用动态度指数对南水北调中线水源区1990—2010年土地利用空间格局特征及其时空变化进行了分析。结果表明：1）南水北调中线水源区土地利用类型以林地、耕地、草地为主，其中林地面积占水源区土地总面积的76.00%左右，占有绝对优势。2）1990—2010年水源区土地利用变化主要发生在林地、耕地、草地三者之间，耕地、草地、水域和未利用地均呈现波动变化趋势，林地则呈现先大幅增长后趋稳定，建设用地不断增长，且增长速度不断加快。而这些发生变化的土地利用类型在空间上多分布于人类活动较多的低海拔、低坡度的河谷地区。3）水源区土地利用变化综合动态度为1.20%左右，整体上水源区土地利用变化速度不大，水源区土地利用稳定性整体上较好。
Abstract:
There was an obvious spatial difference in spatial patterns of land use/cover change in the water resource district of Middle-Route of the South-to-North Water Diversion Project. The spatial pattern of land use/cover change in the study area was quantitatively analyzed by using RS and GIS. The results showed that: 1) the land use types were mainly forestland, agricultural land and grassland, indicating that the matrix of landscape is forest; 2) the land use change mainly occurred in forestland, cultivated land, and grassland, the forestland had showed the first increasing and then the stability, the areas of construction land increased drastically, and the growth rate accelerated, land use changes mainly occurred in the gully regions with low altitude and gentle slope where human activity was active; 3) the land use dynamic degree was about 1.20%, the overall changes of land use were slight, and the structure of land was more stable.
