摘要
选取林地面积减少较为严重的滇西北香格里拉县为例,对研究区的土地利用变化驱动机制进行了分析,并集合GIS技术,尝试运用元胞自动机理论构建Logit模型对研究区的土地利用空间格局进行了模拟和预测。模拟的Kappa指数为0.79,表明CA模型在土地利用/覆盖变化的预测方面有巨大优势。
A study was conducted to analyze the land-use change-driven mechanism of forest land in Shangri-La County, northwest Yunnan Province, where the forest land area decreased more seriously. The spatial pattern of land use in the study area was simulated and predicted by GIS technology and the Logit Model obtained from the cellular automata theory. The kappa index of the simulation was 0.79, indicating that the cellular automata model has more advantages in the simulation of Land use/cover change.
