以贵州省麻江县坝芒乡为例，根据1992年和2012年2期遥感影像解译获得土地利用数据，通过计算相关景观格局指数，研究了1992—2012年坝芒乡土地景观格局演变特点。结果表明：1）研究期间，耕地与未利用地面积下降，林地、草地、建设用地和水域面积增加，耕地、林地和草地之间的转化最为突出；2）各土地景观类型的斑块数都有不同程度的变化，林地、草地、建设用地有所增加，耕地、水域和未利用地有所减少，除耕地景观形状指数降低外，其他景观形状指数都呈增加趋势；3）景观多样化指数、均匀度指数和分离度指数呈减少趋势，结合度指数、蔓延度指数和聚集度指数呈增加趋势，反映出该区景观异质性降低，结构趋于简单。退耕还林还草工程以及快速城镇化是贵州山区土地利用景观格局变化的主导因素。

Taking Bamang of Majiang County as a study area,based on the data of land use through remote sensing interpretation on image in 1992 and 2012 . This paper analyzes the landscape pattern change of land use in mountain areas through calculated landscape pattern indices. The results show that 1 )The area of arable land and unused land decline while the area of woodland,grassland,waters and construction land increase. The conver-sion between woodland,grassland and arable land is obvious. 2)The amount of patches for each land-use type changes with different degrees. Woodland,grassland,waters and construction land increase,but arable land and other land decrease. LSI of arable land increases while other land-use types decrease. 3 )SHDI,SHEI and DI-VISION have declined tendency while COHESION,CONTAG and AI are on the rise. It shows the reduction of landscape heterogeneity and simple structure. The conversion of cropland to forest and grassland project and rapid urbanization are the main causes for the changes of landscape pattern in mountain areas of Guizhou.
