基于 TM数据和 GIS技术,通过气候参数插值、地形三维分析、气候参数和景观图与 DEM的叠加、景观参数计算,从不同空间尺度分析了五台山高山带的景观特征。研究认为 :将气候参数插值图和景观组分图叠加在 DEM上,能更好地反映山地景观的格局及其形成机制 ;五台山是华北地区半湿润 -半干旱背景上一个寒冷、湿润的中心 ;海拔 2 890 m以上存在气候上的林线,应划入高山带 。

Based on TM data and GIS technique, the alpine landscape of Wutai Mts was analyzed on different spatial scales by using methods of climate parameters contour map, 3 D analysis of topography, and overlay of climate parameters contour map and landscape map with DEM We interpreted the landscape map from TM image and calculated the landscape indexes We consider that overlay of climate parameters contour map and landscape map with DEM is good to reflect the landscape structure and its mechanism We concluded that Wutai Mts can be regarded as the coldest and wettest center of the surroundings Alpine zone of Wutai Mts lies at an altitude of above 2 890 m Alpine Kobresia meadow is the main element of alpine landscape of Wutai Mts and it is a unique and fragile ecosystem in North China Alpine landscape reserve should be established.
