摘要:
景观指标是生态安全指标的重要组成部分，以小流域为单元的生态安全景观指标体系的构建以及指标提取方法是区域生态安全评价的基础。基于GIS、景观结构分析软件fragstats，制作了小流域土地覆盖景观图。基于数字地形技术实现了小流域的划分，提取了秦皇岛市84个小流域的生态安全景观指标。对小流域土地覆盖景观制图、小流域生态安全评价景观指标体系的构建和提取方法进行了探索。
Abstract:
Qinhuangdao is selected as study area.The establishment and extraction methods of ecological security landscape metrics system of small watershed are very important.The land cover landscape maps of small watersheds are compiled based on the land use interpreted from Landsat ETM+images in 2002.The landscape metrics system is an important part of the ecological security indicator system.Based on GIS and landscape software fragstats,the ecological security landscape metrics of small watersheds were extracted.The establishment and extraction methods of ecological security landscape metrics system of small watershed were studied.
