The Study On Various Forest Plant Community Landscape In Huangsang Nature Reserve

A fruitful study of the succession forest plant community landscape characteristics, pattern and aesthetics was made in Huangsang reserve in this dissertation. The results of the study revealed the reality of the plant community landscape. The results provide theory and practice guidance and reference for protection of forest plant community landscape, management of forest resources, plant community design, forest park planning, nature reserve planning and famous sceneries planning. The results of study are as follows:(1) The study of plant community landscapes shows: 1) Plant flora characteristics include: ① Plant species are rich: A total of 2029 species and varieties falling into 848 genera, 213 families of vascular plants were identified in Huangsang Nature Reserve. ② There are many ancient geographical elements, such as Magnoliaceae and Illiciaceae. ③ The transition of the plant flora is obvious. ④ The feature of endemic to this flora is rich: There are 23 Chinese endemic genera. There are 735 Chinese endemic species, making up 39.5% of the total species. ⑤ The geographical elements of the flora are complexity. The flora communication with other flora is comprehensive. 2) Forest vegetation was classified into 3 vegetation type groups, 9 vegetation types, 41 association. 3) The main plant community landscapes are as follows: Form. Castanopsis fargesii; Form. Schima argentea; Form. Fagus lucida; Form. Lithocarpus glaber; Form. Corylus chinensis; Form. Liriodendron chinense; Form. Betula luminifera; Form. Liquidambar formosana; Form. Pinus Kwangtungensis; Form. Machilus leptophylla; Form. Pinus massoniana; Form. Cunninghamia lanceolata; Form. Phoebe bournei; Form. Michelia platypetala; Form. Cephalotaxus fortunei; Form. Rhododendron simsii; Form. Phyllostachys heterocycla. 4) The more the plant community landscape structure is complex, the higher its diversity index is. Every plant community landscape has a high diversity level. 5) The plant community landscape structure is complex. The plant community landscape usually has three lays and a lot of species. There are some special forms in some gully or gloomy slope, such as Form. Amentotaxus argotaenia. 6) The plant community landscapes have obviously vertical distribution: There are evergreen broadleaved forests under altitude 1200m. There are evergreen and deciduous broadleaved forests...
