中文摘要	景观生态影响评价是非污染生态环境影响评价的重要组成部分,对于区域生态治理工程尤其关键.该文以大同市南郊区2002～2003年的生态治沙工程为例,以2001年的1∶50000土地利用现状图和2002年、2003年的1∶10000治沙工程设计图为基础数据,对工程实施前后的区域景观格局与景观生态影响进行对比分析.结果显示,大同市南郊区2002～2003年治沙工程总体使该区景观向着有利于沙化逆转的方向发展,表现为研究区景观水平的分形维值降低,未利用地以及耕地等占优势且高度聚集的状态得以改善,使景观的多样性提高;使耕地和林地景观类型水平分形维下降,未利用地景观类型水平分形维值升高;山区半山区乡镇的景观水平分形维值降低,耕地和未利用地的聚集度和优势度下降,林地和牧草地的聚集度和优势度上升.
英文摘要	Landscape ecological impact assessment is an important part of non-pollution ecological and environmental impact assessment, and plays significant role in regional ecological items. Taking the project of controlling desertification in the southern suburb of Datong city from 2002 to 2003 as an example, the landscape ecological impact assessment is conducted based on the 1 ：50000 land use map in 2001 and the 1 ：10000 project plan map in 2002 and 2003. Regional landscape pattern and landscape ecological before and after the project were compared. Results show that the project can make the landscape more helpful for controlling desertification. The fractal dimension of whole landscape decreases, the status were changed that cultivated land and unused land severely dominate and aggregate, and the landscape diversity was improved; the fractals of cultivated land and forest land were caused to decrease and that of the unused land to increase ; fractal dimension of mountainous and semi-mountainous towns were decreased, as well as the contagion and dominance of cultivated land and unused land, and increasing the contagion and dominance of forest land and grassland of these towns were increased.
