Research On The Protection Of Biodiversity And Green Space System Planning In Sheyang County

The protection of biodiversity is one of the key measures to protect the earth, the ecological system, wild animal and plant resource, and the human survival environment. Nowadays, the world is faced with five crisis: population, resourced, environment, grain and energy. The solution of these crisis have close relationship with the protection of biodiversity on the earth.Green ecosystem is an important place of embodiment of biodiversity. As green plants play a key role in maintenance ecological balance, the protection and good planning of the system has positive impact on the protection of entire ecosystem on the earth.In this study, an analysis is made on the vegetation type, forest distribution, ecosystem maintenance, protection of biodiversity and natural protection zone in Sheyang County.The ecosystem in Sheyang county is important in the protection of plant diversity. It is particularly important to make good plan of the protection of original species ( rare poultry such as red-crowned crane) and original biological kind (such as reed marshes and salt Hao etc.). Based on the reasonable relationship between protection and development, three different zones are designed in the plan: the first one is the core protection zone, aiming at protection of original species, which is located in the most resource-rich area and the gene storehouse in the county; the second one is the buffer zone, which is easily subject to human behavior; and the third one is proper development zone, which is located around the buffer zone, and make good use of the unique natural and ecological view sight.The green ecosystem protection system in Sheyang county is aimed at protecting biodiversity, and is composed of a "central district", a "green ecological gallery" and a "blue ecological gallery". The central district is the county of Sheyang. The design of green spaces in the county includes majortransportation routes, common public green areas and rest places, with the hope of beautifying the environment as well as protection of the biodiversity of the county. The green gallery design includes the, forest belt along the high way of "Lian-Tong" and the railway that terminates in Sheyang port. The forest belt will be designed as 100 meter wide, with high arbor as main plants, dotted with bushes and Land quilt plant, such as flowers and grasses, creating a biological space with multi layers of viewsight.The blue ecological gallery is designed around the three rivers: Sheyang river, Huangshagang river and Xinyanggang river. It is designed for the protection and improvement of the ecological environment alone the rivers.
