水土保持自然生态修复作为生态建设的一项主要任务,需要进行水土保持生态修复适宜区研究。论文以陕西省为例,应用ArcGIS 9.2空间数据分析工具,综合分析土地利用类型、年降雨量、土壤侵蚀、人口密度等指标,划分出陕西省水土保持自然生态修复适宜区域,并分析了陕西省水土保持综合治理实施情况。结果表明,陕西省水土保持自然生态修复区面积为23 911km2,秦岭大巴山区适宜自然生态修复的面积最大,研究为水土保持综合治理下一步实施提供借鉴意义。
As a major task of ecological construction, soil and water conservation natural ecological restoration needs to be studied on the appropriate area for ecological restoration of soil and water conservation. Taking Shaanxi Province as an example, this paper uses ArcGIS 9.2 spatial data analysis tools to comprehensively analyze the land use types, annual rainfall, soil erosion, population density and other indicators, and divides the suitable regions for soil and water conservation in Shaanxi Province. Comprehensive implementation of soil and water conservation. The results showed that the area of natural ecological restoration of soil and water conservation in Shaanxi Province was 23 911 km 2, and the area suitable for natural ecological restoration was the largest in the mountainous area of Qinling Dabashan Mountain. The study provided reference for the next step of comprehensive management of soil and water conservation.
