新疆维吾尔自治区土壤侵蚀遥感目视解译与计算机制图

<正> 新疆维吾尔自治区面积1649590Km~2(不包括国界争议地区),占全国土地面积的1/6,是我国最大的一个省区。除了部分绿洲,绝大部分是沙漠。可利用地面积很少。为了了解新疆可利用地的分布情况,为新疆的整体规划提供依据。我们用遥感目视解译与计算机制图,建立了新疆维吾尔自治区的土壤侵蚀图的8位

Visual interpretation and computer mapping in aspect of soil erosion in Xingjiang Uygur Autonomous Region

Xingjiang Uygur Autonomous Region,with 1649590 km2 ofarea,one-sixth of the total area of China,is the largest autonomous region in China. Through mounting the satellite imageson the 1 /500000 topographic maps of international standard, with the method of visual interpretation, field survey and establishing reference plots of soil erosion, a 8 order geocode model has been developed, and a soil erosion's draft map is input into a computer in which such processes are conducted as area calculation, projection transfer, map mounting, scale reduction, geocode processing, and in the end, producing a computerized soil erosion map of high accuracy. According to the research result,wind, water and frozing-melting erosion area respectively accouts for 50% ,35% and 15% of total area of the region.
