摘　　要：本文在土壤与草地资源调查的基础上,本着综合性、广泛性、一致性的原则,依据地形、土属、植物群丛组把锡林河流域草地地境划分为:中丘—砂壤质碳酸盐黑钙土—线叶菊、大针茅旱生杂类草地境;中丘—中厚层黑钙土—羊草、杂类草地境;低丘—砂壤质暗栗钙土—大针茅、旱生杂类草地境;缓坡—厚层暗栗钙土—羊草、大针茅地境;平地-壤质栗钙土-大针茅地境;河漫滩-腐殖质沼泽土—苔草地境;阳坡—紧砂土—山杏、羊柴地境;阴坡—紧砂土—稠李、漏斗叶绣线菊地境;丘间低地—沙栗土—大针茅、糙隐子草地境等9个地境,并对每个地境的植被、土壤和地形特点进行了描述。Through the surveys on soil and vegetation the principles of syndrom, extensivity, consistency were used to devide the rangelands in Xilin River Watershed into 9 range sites： Mid-part of hill/ sand loam carbonate black chestnut soil / Filifolium sibiricum ＋ Stipa grandis ＋ xeric forbs plant community range site, Mid-part of hill/ mid--deep balck chestnut soil/Leymus chinensis ＋forbs plant community range site, Low hill/ sand loam dark chestnut soil/Stipa grandis ＋xeric forbs plant community range site, Slight slope/deep dark chestnut soil/ Leymus ehinensis ＋Stipa grandis plant community range site, Plain/loamy chestnut soil/ Stipa grandis plant community range site, Flood land/humus bog soil/ Carex korshinskyi plant community range site, South slope/tight sand soil/ Prunus ansu --Hedysarum leave plant community range site, North slope/tight soil/Prunus padus ＋Spiraea aquilegifolia plant community range site, and iowland/chesrnut sand soil/ Stipa grandis ＋Cleistogenes squarrosa plant community range site.
