| 摘 要： | 农田渠系工程作为土地整理中农田水利工程的主要构成部分，其生态功能评价有着重要意义。选择湖北省孝昌县白沙镇基本农田土地整理项目西区为研究区域，根据农田渠系的生态功能特性，将其分为两类:生态功能型和非生态功能型沟渠，通过运用景观格局分析方法，通过对比传统景观分析方法和考虑生态性的景观分析方法对研究区域的7种类型渠系进行测算。结果表明，研究区渠系在两种分析方法下，景观指数有较大差异；同时，研究区生态功能渠系形成了10个渠系孤立岛，对依赖渠系廊道进行迁移、生存和庇护等的生物影响大。

| Abstract: | As the main part of agricultrual hydraulic engineering in land consolidation，the ecological function evaluation of cultivated land ditches is significant to land consolidation.Basic farmland in Baisha town of Xiaochang County of Hubei Province was selected as the study area and the ditches corridors was classified into two kinds:ecological functional and non-ecological functional ditches.Through applying landscape pattern analysis method，landscape index of seven types of ditches were calculated.The results indicated that there was great difference between adopting two analysis methods in ditches of study area，furthermore，after excluding non-ecological ditches，ten ditch islands were formed in this area，which affected the animals’migration，living and biological shield which were dependent on ditches system. |
