摘要: 通过野外调查、遥感影像解译和Fragstats 3.3软件平台,基于斑块和景观两个尺度对通天河干流流域水电4组梯级开发方案对景观格局的影响进行分析评价。结果表明:2008年通天河干流流域景观格局总体特征为草地是优势景观类型,其次为裸地和林地。方案4对斑块水平上的景观指数和景观水平上的格局影响最小。

Abstract: On the basis of geography,ecology and spatial analysis in conjunction with data collected from field observations and TM/ETM images acquired in 2008,the database for the study site was constructed.Then landscape indexes,like patch size/density,patch shape,aggregation/dispersion and diversity were calculated and analyzed by means of Fragstats3.3.Results indicate that grassland,bare areas and forestland are the dominant landscape types in 2008,and Scheme 4 had less effect on the landscape pattern.

Key words: Tongtian River, cascade hydropower development, landscape pattern
