宁夏水土保持及区划研究

Study on Soil and Water Conservation of Ningxia and It's Division

简述了宁夏的生态环境,论述了宁夏水土保持的重要性及总体方向。根据宁夏生态环境状况,将其划分为5个水土保持区,即:①银川平原水土资源基本平衡区;②贺兰山森林草坡轻度流失区;③盐池—同心沙漠化草原中度流失区;④海原—固原草原强度流失区;⑤六盘山疏林草原中度流失区。为宁夏的水土保持、生态环境建设和区域经济发展提供了科学依据。

The ecological environment of Ningxia is briefly described and the importance and channel of soil and water conservsation of Ningxia are discussed. Ningxia is divided into 5 water and soil conservation areas on the basis of its ecological environmental conditions. They are： ①the basic blance area of water and soil resources in Yinchuan plain;② the area with light water and soil loss of the Helan Mountains forest lawn,③the area of moderate water and soil loss of Yanchi-Tongxin desertization grasslands;④ the area with intense water and soil loss of Haiyuan-Guyuan grasslands;⑤ the area of moderate water and soil loss of the Liupan Mountains sparse forest grasslands. It provides scientific basis for the water and soil conservation,ecological environmental construction and regional economic development of Ningxia.
