摘　　要：在风资源评估过程中,高精度地形数据通常较难获取,寻找一种可替代数据变得非常重要。针对风资源评估中经常存在的地形测绘和地表状况考察困难的问题,以云南高海拔复杂山地风电场-DGS风电场为应用案例,尝试将90 m分辨率的SRTM地形高程数据用于绘制Meteodyn_WT软件所需的电子地形图,并分别采用SRTM数据绘制的地图与实测1∶10 000的高斯地图所得到的风资源评估结果进行对比分析,得出SRTM数据可用于高海拔复杂地形的风资源评估的结论 。In wind resource assessment, high resolution terrain data is usually difficult to be obtained, thus finding the alternative data is particularly important. In view of the fact that it is very difficult to conduct topographic mapping and ground investigation for wind resource assessment, based on the case of a DGS wind farm in mountains with high altitude and complicated terrain in Yunnan province, it is tried to use SRTM data of 90-meter resolution for acquiring the electronic topographic map, which is needed in Meteodyn WT model. A comparison is made of the wind resource assessment results based respectively on the electronic topographic map and the surveyed 1：10 000 gauss map, which can be concluded that the SRTM data can be used for wind resource assessment in mountains with high altitude and complicated terrain.
