%X This data is based on the 1:50000 and 1:100000 base maps of Hexi and Ejina drawn by Lanzhou Desert Research Institute of Chinese Academy of Sciences and supplemented by investigation. Reference is made to: (1) land type map of Zhangye area in Gansu Province and Alxa Right Banner in Inner Mongolia (compiled by Chen Longheng, 1:250000); (2) soil map of Beidahe River Basin (compiled by Li Fuxing and Yang, 1:100000); (3) land type map of Ejina Banner Delta in Inner Mongolia (compiled by Ejina Banner delta investigation team of Lanzhou Desert Research Institute, Chinese Academy of Sciences, 1:250000). The mapping adopts the methods of basic map data, field route inspection as the main part and interpretation of aerial and satellite films. This drawing was compiled by Li Fuxing and Qiu Baoming, with Zhang Ziyu taking part in the work; the drawings are Peng Jilong, Wang Xizhang and Guo Yingsheng. The soil classification research group of Nanjing Soil Research Institute of Chinese Academy of Sciences and Li Jin provided classification and mapping specifications. According to the soil classification system of China and the field situation, the soil in Heihe River Basin is divided into 8 soil classes, 12 sub classes, 23 soil classes and 60 sub classes. Its purpose is to reflect the main soil types, combinations and distribution laws in this area, and reflect the regional characteristics of soil, comprehensively display the generalization of soil resources, and provide the basic scientific basis for estimating and evaluating the quantity and quality of land resources, the rational use of land resources and the rational redistribution of water resources in river basins.
