Hunan Shiyan Lake Forest Park Plant Community Structure And Forest Research

With the development of urbanization and people growing demand for ecological environment, construction of urban forest park occupies a more and more important role in urban construction, the plant community is an important elements of forest park, through the study of plant community structure and scientific laws of succession, The research of the reform of forest for perfecting plant community structure of the urban forest park, improving the anti-interference ability of forest ecosystem, improving forest quality, riching, and beautifying the landscape is of great significance,It is the inevitable requirement of sustainable development of forestry.This paper surveyed a variety of typical plant communities in Spirifer lake forest park by using the method of sample plot survey. It researched and analysised the spirifer lake status and structure features of main plant communities.by community composition analysis, the characteristics of each typical analysis, plant size order analysis, the important value of dominant species and community diversity and so on. And selected the spirifer lake forest park of coniferous forest, mixed needle, deciduous broad-leaved mixed forest, bamboo forest, economic forest road landscape as the research object, It analyzed the vegetation status and existing problems, And aimed at these problems puts forward the corresponding reform Suggestions. The results are as follows:(1) The typical plant communities of spirifer lake forest park has coniferous forest vegetation types of pinus massoniana+fir-mountain pepper-kidney fern, broad-leaved forest vegetation types of liquidambar oil-tea-gardenia community, camphor, paulownia and German oak-privet-snake grass communities, hackberry+chongyang wood-mosquito mother-mountain crab grass communities, bright leaf beech+pulse cyclobalanopsis-the heather-kidney more single dominant species of bamboo-kidney fern fern community community, mixed needle leaf and pinus massoniana schima superba+- differential renal fern community,+masson pine camphor-mountain pepper-snake grass communities, etc.(2) and masson pine camphor is an important value in the arbor layer, the highest is the advantage of plant community species spirifer lake, it will be spirifer plant community succession in the direction of the lake. In addition, schima superba, hackberry, bright leaves beech, etc. The important value is also high in plant community, is lake spirifer time advantage of the types of plant community.(3) Community structure in spirifer lake in pinus massoniana schima superba+-oil-tea-kidney fern community, hackberry+chongyang wood-mosquito mother-mountain crab armor grass community is the highest plant community in the community diversity.(4) Analyze and summarize the diameter structure characteristics of dominant species of plant communities in Shiyan lake.(5) Spirifer lake is analyzed several main problems of vegetation types and corresponding forest reform measures are put forward.
