水土保持区划是水土保持规划的基础和关键技术环节。北方风沙区三级区划是在全国水土保持一、二级区划框架上进行的,主要依据是《全国水土保持区划导则(试行)》相关原则和指标体系,区划结果是将北方风沙区划分为准噶尔盆地北部水源涵养生态维护区、天山北坡人居环境农田防护区等12个三级区。对12个三级区的水土保持功能、命名方法进行了分析评价,结果表明将北方风沙区分为4个二级区、12个三级区是合理、可行的。
Soil and water conservation zoning is the basis of water and soil conservation planning and key technical aspects. The three divisions of the north windy sand area are carried out in the framework of the first and second level of soil and water conservation in the country, which is mainly based on the relevant principles and index system of “Guidelines for Zonation of Soil and Water Conservation in China (for Trial Implementation)”. The division result is divided into The northern part of the Junggar basin is under water conservation and ecological maintenance zone, and the Tianshan north slope is home to 12 farmland environmental protection zones. The function and nomenclature of soil and water conservation in 12 tertiary areas were analyzed and evaluated. The results showed that it is reasonable and feasible to divide the north wind and sand into 4 secondary areas and 12 tertiary areas.
