The Study On The Ecology Planning Of Green Space System Of Shi Hezi City

Shi Hezi is a model artificial oasis city, it is also an arid area city, which is only awarded "the Chinese occupies environment prize" by the United Nations. Shi Hezi city can receive this great honor because of the Green Space System planning. Shi Hezi City takes great practice in building urban green space system in the construction of ecological city. From view of ecology, urban green space is a very important life infrastructure in urban environment; it is one of the city's ecological systems with negative feedback function ecology subsystems. It provides the oxygen for city biology, regulates the temperature and purify the pollution through a series reflection of ecological green plants .It has the relative independence. It is irreplaceable in improving the urban environment quality, maintaining the city ecological equilibrium, beautifying the environment. To achieve the rational green space system planning of ecological city, it is necessary to have a specific, practical and reasonable theory to guide the ecological city's construction. According to landscape ecology, in accordance with the theory of urban planning, ecology and landscape, and based on qualitative and quantitative analysis, this paper firstly analyses landscape ecological construction indicators about green space such as landscape composition, landscape diversity index, landscape dominance index, landscape evenness index, landscape fragmentized degree, landscape corridor density, and public green plot area etc. This paper starts the research of landscape ecological construction of green space system in Shi Hezi.This paper elaborates mainly on the principles, indexes of ecological landscape planning of Shi Hezi green space system and distributions of green space. Besides, it bases on the contents above. According to analysis and judgment, the paper does study on the ecological landscape planning of Shi Hezi city green space system, trying to provide scientific support for future ecological landscape planning of urban green space system.This article mainly contains five contents. The first part is summary of materials, which mainly looks back on the general situation of the planning of green space system in China and abroad. The second part is about the principles and methods of landscape ecology in urban green space system. The third part is about analyzing the background of green space system of Shi Hezi city. The forth part is about the landscape and ecological analysis and judgments on the green space system of Shi Hezi city. The fifth part is about the ecological landscape planning of green space system of Shi Hezi city.
