  开展区划是在实地考察基础上，参考朱震达“中国北方地区沙漠化治理区划图”、中国植被分布图（100万）、中国土壤分布图（100万），并结合中国土地覆盖数据和数字高程模型（DEM）开展综合区划。

\n

  一、 区划原则

\n

  1. 自然地带原则

\n

  研究区横跨东西1500多公里，南北1300多公里，受降雨的地带性分布影响，自东南向西北形成了半湿润区向半干旱区，再向干旱区转换的自然地带分布，在不同的自然地带中，沙漠化的发生成因、发展过程、表现形式和沙漠化土地的分布、程度、发展趋势均有不同，导致防治途径具有比较明显的地带差异。

\n

  2. 沙漠化发展阶段和程度原则\n在同一自然地带内，由于沙漠化过程的发展阶段和程度不同，防治的方法和侧重点也会不同。

\n

  3. 自然条件、资源利用与区域可持续发展方向一致性原则

\n

  在一个自然地带内，沙漠化土地成因、土地利用方式和强度、资源开发方向、生态保护等主要方面表现出明显的地域差异。尤其在资源利用开发和区域可持续发展方面，差异更为明显，表现在对沙漠化土地防治的原则、方法和措施上也有所不同。

\n

  二、 区划指标体系

\n

  1. 沙漠化防治一级区

\n

  在沙漠化发生的半干旱区（包括部分半湿润区），随着人类活动的不断扩展，逐渐形成了牧区、农牧交错区和农区等自然和人文混合的景观类型，而这些自然和人文的景观是沙漠化土地形成、发展的基础，并决定了沙漠化防治的重点和措施。因此，沙漠化防治一级区的确定由自然带确定的气候类型（半干旱区和半湿润区）和人类活动（牧区、半农半牧区和农区）两类指标作为划分依据，将半干旱区（包括部分半湿润区）的沙漠化土地划分为I半湿润农业区、II半干旱草原区、III半干旱农牧交错区、IV 半干旱灌溉农业区四个一级区。

\n

  2. 沙漠化防治二级区

\n

  沙漠化土地的二级分区是在一级分区的宏观格局控制下，依据沙漠化的成因、类型、强度、发展趋势以及治理途径在一定区域内的一致性和区域之间的差异性，将半干旱区（包括部分半湿润区）的沙漠化土地划分为13个二级区。", "ds_source": "

 1、 Zoning principle

\n

 1. Principle of natural zone

\n

 The study area spans more than 1500 kilometers from east to west and more than 1300 kilometers from north to south. Affected by the zonal distribution of rainfall, a natural zone has been formed from southeast to northwest, from semi humid zone to semi-arid zone, and then to arid zone. In different natural zones, the causes, development process, manifestations, distribution, degree and development trend of desertification land are different, There are obvious regional differences in control approaches.

\n

 2. Principle of desertification development stage and degree

\n

 In the same natural zone, due to the different development stages and degrees of desertification process, the prevention and control methods and emphases will also be different.

\n

 3.Principle of consistency between natural conditions, resource utilization and regional sustainable development.

\n

 In a natural zone, there are obvious regional differences in the causes of desertification land, land use mode and intensity, resource development direction, ecological protection and so on. Especially in resource utilization and development and regional sustainable development, the difference is more obvious, which is also reflected in the principles, methods and measures of desertification land prevention and control.

\n

 2、 Zoning index system

\n

 1. Grade I desertification control area\nIn the semi-arid areas where desertification occurs (including some semi humid areas), with the continuous expansion of human activities, natural and human mixed landscape types such as pastoral areas, Agro pastoral ecotones and agricultural areas have gradually formed, and these natural and human landscapes are the basis for the formation and development of desertification land, and determine the key points and measures of desertification prevention and control. Therefore, for the determination of the primary desertification prevention and control area, the climate type (semi-arid area and semi humid area) and human activities (pastoral area, semi-agricultural and semi pastoral area and agricultural area) determined by the natural belt are used as the division basis, and the desertification land in the semi-arid area (including part of the semi-humid area) is divided into I semi-humid agricultural area, II semi-arid grassland area, III semi-arid agro pastoral ecotone IV semi-arid irrigated agricultural area is divided into four first-class areas.

\n

 2. Secondary area for desertification control

\n

 The secondary division of desertification land is to divide the desertification land in semi-arid areas (including some semi humid areas) into 13 secondary areas under the control of the macro pattern of the primary division, according to the causes, types, intensity, development trend of desertification, the consistency of treatment approaches in a certain area and the differences between regions.
