中文摘要	利用喀斯特石漠化生态脆弱区贵州贞丰县2004年的ASTER遥感影像，解译了全县的喀斯特石漠化现状，并从景观生态学的角度指出轻、中、强、极度石漠化存在不同的空间分布格局。与此同时，作者还把石漠化的景观格局和其土地生态价值的分布频率结合起来，并从生态系统服务功能的角度定量计算了相应喀斯特石漠化土地的相对生态价值，评价了研究区石漠化土地的生态效应。结果表明，贞丰县270个村的生态价值整体偏低，全县极大值为1．016，极小值为0．286；不同区域之间的总体生态价值差异较大，生态价值相对较好的地区主要集中在非喀斯特地带，而在中度、强度、极强度石漠化地区生态价值很低。
英文摘要	The ASTER remote sensing image in 2004 in fragile parts of karst rocky desertification area in Zhenfeng county,Guizhou province is used to translate the county-wide karst rocky desertification present situation. Furthermore, the spatial distribution pattern of different extents of rocky desertification, the light, the moderate and the intensified ones is pointed out from landscape ecology aspect. And at the same time, in order to express quantitatively the degree of land degradation and the corresponding ecology value in rocky desertification parts of different extent, the rocky desert landscape pattern and its land ecology value distributing frequency are combined, the relative ecology value of the corresponding karst rocky desert land is calculated from the aspect of ecosystem service function and the ecology effect of rocky desert land is appraised. The results indicate that the ecologic value of 270 villages in Zhenfeng county are somewhat low, the county-wide maximum value is 1. 016, minimum 0. 286. According to the ecologic value, the research area is divided into 7 parts. The total ecologic value in different parts is quite different. The areas with higher ecologic value mainly concentrate in the non-karst region, but in moderate, intensified and extremely intensified rocky desertification areas the ecologic value are extremely low.
