摘要
以贵州苏铁自然保护区主要森林群落类型为例,选择木荷群落、任豆群落、白栎群落和化香群落为研究对象,基于模糊综合评判理论,选取物种多样性、M.Godron稳定性值、演替现状、干扰强度和优势种年龄结构5项指标作为构建评判模型的参数,通过计算函数隶属值来评判森林群落稳定性。结果表明:4种典型森林群落稳定性表现为木荷林>任豆林>白栎林>化香林,评判结果符合当地森林群落发育状况。对森林群落稳定性评判旨在为该地区森林培育和经营提供理论支撑。
The forest community stability was evaluated by calculating subordinate function values of a model which was established based on fuzzy synthetic evaluation by five indices which contained species diversity,M.Godron stability values, succession status,disturbance intensity and the age structure of four dominant species,following Schima.superba forest, Zenia insignis forest,Quercus fabri forest and Platycarya strobilacea forest. The results showed that the forest community stability evaluation of four main forest communities in Cycas guizhouensis nature reserve ranked in the decreasing order was Schima.superba forest,Zenia insignis forest,Quercus fabri forest and Platycarya strobilacea forest. And the result conformed to the local community development status of forest. The purpose of evaluating the forest communities stability was to gain the purpose of management of forest cuhivation and providing theoretical support.
