摘 要:以彭阳县为例,根据退耕还林(草)原则,进行退耕还林(草)林草配置相关的坡度、坡向、土壤侵蚀、水系和居民地等多源数据的GIS空间分析,科学合理地选择退耕还林(草)林草配置模式,应用GIS技术的空间分析功能,使林草配置模式选择科学化,为宁南山区及宁夏全境内的退耕还林后续规划、决策提供了科学有效的范例。Taking Pengyang County as an example, according to the principles of returning cropland to forest (grass), how to scientifically and reasonably choose forest and grass model of returning cropland to forest (grass) in PengTang County was discussed based on GIS. Through the research method of spatial analysis of GIS, the proportion of forest to grass, the area and distribution of cropland were anglicized under the conditions of soil erosion, slope, river, and the suitable mode was found. GIS technology, provided valid methods and basis to realize the automatization and standardization of the model of returning cropland to forest (grass). It provided an effective example for returning cropland to forest (grass) in Ningxia and the mountain areas of southern Ningxia and the mountain areas of southern Ningxia.
