我国生态脆弱区主要分为水土流失严重型生态脆弱区、土地沙漠化型生态脆弱区、土地盐碱化型生态脆弱区三种类型。目前水土流失严重型生态脆弱区的治理模式主要包括退耕还林还草、植物篱、坡改梯、生态移民、生态自然修复、保护性耕作等。为了达到较好的治理成效,应根据各地实际筛选适合当地的最佳治理模式,实现生态效益、经济效益和社会效益的持续发展。
The ecologically fragile areas in our country are mainly divided into three types: severe soil erosion type ecologically fragile area, land desertification ecologically fragile area and land salinization ecologically fragile area. At present, the management models of severe ecological loss in soil and water loss mainly include returning farmland to forest and grassland, hedgerows, slope to ladder, ecological migration, ecological restoration and conservation tillage. In order to achieve better governance results, we should select the best local governance model based on the actual situation in each region to achieve the sustainable development of ecological, economic and social benefits.
