文峪河流域;优势种;密度结构
摘  要：
研究了文峪河上游3个河段6种不同生境条件下群落优势种组成及其密度结构,结果表明:1)青杄林河段植被处于演替顶级或近顶级阶段,受人为干扰极小,是一种典型的地带性植被类型;2)白桦林河段植被如能避免或减少人为干扰,河岸带有可能向白杄林方向演替,高地森林则会在较长时间内处于针阔混交林阶段;3)农田河段河岸带植被已基本退出自然演替序列,高地华北落叶松林将在较长时间内保持稳定状态。

摘  要：
The population index of dominant species,such as number,density,age structure and distribution pattern,was conducive to evaluating the strength of community interference,determining the trend of community succession.In this paper,we systematic ouy studied the composition and density structure of dominant species of the three reaches and its six different habitat conditions of the Upstream of Wenyuhe Watershed.The results showed that:(1) the vegetation of Picea wilsonii forest reach was in the succession stages of climax community or near climax community,had minimal human disturbance,and had been in a typical zonal vegetation types;(2) If human disturbance could be avoided or reduced in Betula platyphylla reach,the riparian forests would develop to Picea meyeri forest and upland forests would stayed in the mixed coniferous stage in a very long time;(3) the riparian vegetation of farmland reach had quit basically out of natural succession,the Lair principis-rupprechtii upland forests would remain a steady-state in a long period.The paper also raised some vegetation management measures for every reach in Wenyuhe Watershed Upstream.
