摘　　要：采用法瑞植物社会学学派的理论和方法对易门绿汁江、十街河河谷植被进行了分类研究,得到一包括2个群属、4个群丛和1个群丛相的分类系统单位,各分类单位均有自己的一套种类组合。分类结果经系统聚类法所验证。Lu Zhi River and Shi Jie River of Yimen county are situated at the center part of Yunnan plateau (the mountainous watershed of two typical dry-hot valley Yuan Jian and Jin Sha River), and belong to the upper reaches of Yuan Jian River. According to the methods of French-Swiss phytosociological school, the valley vegetation is classified into two allia.nce:woodfordio-Heteropogonion contorti and Osyrio-Heteropogonion contorti; four associations: 1. Wendlandetum tinctoriae. 2 Aristidetum adsensionis, 3. Cayopteretum forrestii, 4. Osyrietum wightianae: and one facies: Fac. Dodonaea angustifolia. These results have been proved by the method of system cluster. Because of the geographic-situation and the topographic-geomoephic characteristics of these valleys, the flora and the ecological characteristics of the vegetation are somewhat similar to the dry-hot valley vegetation of Yuan Jian River. But the temperature is lower and the altitate above sea level is higher, the vegetation has some transitional characteristics of the vegetation from Yuan Jian river to Jin Sha River.
