<p>The Ruoqiang Oasis Water System refers to the water system formed by the rivers that nourish the Ruoqiang Oasis. These rivers mainly include Milan River, Tassayi River, Ruoqiang River, Washixia River and Hongliugou, with main streams of 216.82 km, 190.22 km, 166.82 km, 159.95 km and 108.87 km respectively (Lambert projection). The mountainous part of the Ruoqiang Oasis River Basin is the catchment area in the upper reaches of the rivers that maintain the Ruoqiang Oasis. The geographical location of this part of the basin is 37°47'27" N-39°13'27" N, 86°47'04" E-90°34'39" E. The basin area of this part is 19,382.27 km² (Albers projection), and the basin boundary length is 1,149.58 km (Lambert projection). The elevations of the mountainous parts of the Ruoqiang Oasis and the River Basin are all above 1000 m. Areas with elevations below 1500 m are classified into Category 1; areas above 1500 m are divided into 11 types at intervals of 500 m. The dataset was developed based on Google Earth images, ASTER GDEM 30m data, and measured data. The content of the data set includes: (1) water system data of Ruoqiang Oasis;(2) boundary data of some mountainous areas in the Ruoqiang Oasis River Basin; and (3) elevation classification data of the mountainous areas in the Ruoqiang Oasis River Basin. The dataset consists of 33 data files stored in.kmz,.shp and.tif data formats, with a data volume of 23.1 MB (compressed into 3 files, 15.7 MB). </p>
