为了制订有效的水土保持规划和实施土壤保持项目，以稳定土地生产力，依据地力分级图上 的土壤特性（土层厚度、质地、坡度和可蚀性），将印度全国划分为１７个土壤保护带。每一土壤保持 带面积的最终确定依据于国家流域规划图，保证土壤保护带的界定同最近的自然流域、支流风流 域、盆地或水源带相一致。同时，依据占主导地位的土地利用、生产潜力、植物蒸发蒸腾量、水资源 开发潜力、一般侵蚀速度以及与该区域土壤保护相关的人口支持能力和技术创新等问题，进一步将 土壤保护带区划为作为基本管理单元的土壤保护区和被称为小流域的土壤保护单元。在 １：５０ ０００ 比例尺图上，每一土壤保护单元面积约为 １５００～ ２ ０００ ｈｍ２。土壤保护单元水平的规划将能为全国 范围的土壤保护规划和稳定并扩大生产提供途径。
To develop effective soil and water conservation planning and soil conservation programs to stabilize land productivity, India is divided into 17 soil conservation zones based on the soil characteristics (soil thickness, texture, grade and erodibility) . The final determination of each soil holding zone is based on the national basin plan, which ensures that the boundaries of the soil conservation zone are consistent with the most recent natural catchments, tributaries, basins or water zones. At the same time, based on the dominant land use, production potential, evapotranspiration of plants, potential for water resources development, general erosion rate, population support capacity and technological innovation related to soil protection in this area, the soil protection zone was further zoned as Soil conservation areas as basic management units and soil conservation units called small watersheds. On a scale of 1: 50,000, each soil protection unit has an area of about 1500-2000 hm2. Horizontal planning of soil conservation units will provide a means of planning and stabilizing and expanding production of soil protection across the country.
