摘要/Abstract

摘要：

基于1ha样地的群落学调查，研究了云南绿汁江下游河谷两岸的季雨林植被。结果显示：该群落高15~20m，乔木层分为明显的两层，由落叶的厚皮树和常绿的灰毛浆果楝等树种组成；样地内共记录维管植物116种，其中乔木层树种36种，灌木14种，草本43种，藤本21种，附生植物2种；综合1ha样地计算所得乔木层树种ShannonWienner指数为22824，Simpson指数为08321；样地中共记录到胸径≥1cm的树木1764株，且以中、小径级占优势；该群落主要以高位芽植物为主，并且以单叶、纸质、全缘和非尾尖的植物种类和小叶植物为主；群落的种——面积曲线在取样面积为2000m2时趋于平缓，建议将2000m2作为其最小取样面积。根据乔木第一层与第二层的优势种，将该群落初步定为厚皮树——灰毛浆果楝林。

Abstract:

Based on the investigation of 1ha plot, the primitive monsoon forest on the valley of lower Luzhi River in Yunnan was studied. The height of the community is 15-20m, and tree layers are divided into 2 layers, which is dominated by deciduous tree species Lannea coromandelica and evergreen tree species Cipadessa cinerascens. One hundred and sixteen vascular plant species were recorded from the plot, including 36 tree species, 14 shrub species, 43 herbaceous species, 43 liana species and 2 epiphyte species. ShannonWienner index is 22824 and Simpson index is 08321 from the 1ha plot. Total 1764 trees individuals with DBH ≥1cm were recorded in the plot. This community is dominated by phanerophytes. The forest is dominated by the microphyllous species which makes up 3932% of the total. The forest is also dominated by the species with simple leaves (make up 7350%), papery leaves (make up 6923%), none caudate leaves (make up 8120%) and entire leaves (make up 6752%). The species/area curve shows that it is flatten at 2000m2, which is suggested to be the minimum sampling area for the forest. This community could be recognized as Lannea coromandelicaCipadessa cinerascens formation.
