以MODIS影像作为基础数据,提取研究区增强型植被指数(Enhanced Vegetation Indices),运用最佳坡度系数截取法(The Best Index Slope Extraction)和Savitzky-Golay滤波法对影像进行处理,使用二次差分法计算波峰数后与土地利用现状图叠加分析,最后分析结果,并提出建议。
Damp-heat karst mountainous areas are unique areas in terms of socialeconomic development, resource endowment and eco-environment in China, where natural resources are abundant,unique and diverse. However, fragile eco-environment, undeveloped economy and culture, and conflict of human and environment should not be ignored. In the research, a framework of integration of resource-development and environment-protection in damp-heat karst was designed on basis of resource and environment integration, which was applied to Daxin County in Guangxi Province. Furthermore, some integration models were proposed, including integration of development of characteristic agricultural resources and protection of eco-environment, integration of development of manganese ore resources and protection of eco-environment, integration of development of tourism resources and protection of ecoenvironment and integration of development of clean energy and protection of eco-environment.
