Analysis Of The Forest Community And Investigation Of The Ecological Landscape Forests Reconstruct Technique In Sunan

The timber woodland came into city from suburb or country with the speedup urbanization. To satisfy the need of city growth, the woodland should be constructed into landscape forest to resume or improve ecological environment, enhance landscape views and increase ecological benefits.The site types, vegetation species, floristics was researched, and the vegetation community dynamics, succession, zonations and landscape effect was studied in the Longbei Mountain forest park in Yixing. The results show that: The land types could be divided into 8 groups which are flat rice soil, upgrade brown red soil, downgrade yellow brown soil et al. on the foundation of water and fertility gradient. Most of the soil types were yellow brown which was better for the vegetation. The forest communities had 5 types 18 kinds, which were mixed evergreen deciduous broad-leaved forest, coniferous forest, mixed coniferous broad-leaved forest, broad-leaved forest and bamboo et al.. The plants were severity destroyed by human, which caused the fewness broad-leaved trees and artificial firs and horsetail pines. The Longbei Mountain is situated at middle-subtrapiea zone, and the climax community is the evergreen broad-leaved forest, and now is developing to deciduous broad-leaved forest. Otherwise, the economical forests such as bamboo were expanding. The climax community in the area is the result of long time evolution and chooses. The landscape forest construction collocating plants in the form of climax community would build the absolutely natural and healthy ecological environment.This article has put forward the reconstruct notion, aim, object and collectivity distribution on the landscape forest in the forest park. We studied the reconstruction notion, pattern, technique and feasibility about ecological, recreation and culture landscape forest. With the view to forest elements and landscape patterns, using the basic means of touring faction sub area and dispart area landscape design, depending on nature and artificial control, protecting zonation plants, climax communities and forest landscapes, harmonizing the forest and the environment around, the landscape forest reconstruct program directional grew, resumed, maintained, controlled and fostered the forest landscape structure in Longbei Mountain forest park. The ecological landscape forest planted high arbor along chine to protect terrain vegetation and maintain biology diversity on the base of former secondary forest. The recreation one disposed kinds of amusement parks according to the topography to incarnate the harmonious of the culture and human on the base of the former garden, orchard, tea garden, grassplot and so on. The culture landscape one revealed the long history cultures and the great number personalities in the form of Landscape Park in Yixing.
