Study Of The Urban Green Space System And Its Ecological Landscape Pattern Of The Oasis In The South Of Tianshan

In recent years, with the quickening of urbanization, The high-strength development of some artificial oasis has broken the original balance of ecological environment in the southern Tianshan, Which has accelerated the desertification process of this area and seriously threatened the security in ecological environment of the whole oasis belt in the southern Tianshan. So the new urban green land system must be rebuilt, which has the characteristic of this area. What we have done can establish a solid foundation for the oasis city's sustainable development.The essential requirements of urban green space system planning are analyzed from the landscape,the ecological and the economic three perspectives in this article. And the major problem existing in urban green space system planning and construction in this area are put forward .After analyzing the evolution of the oasis in the south of Tianshan and summarizing the characteristics and the principal contradiction in the major cities in this area. on this basis, combining with analyzing the natural and geographical conditions in the oasis of south Tianshan. All the aspects of the urban green space system planning and construction in this area are given new definitions. To exploring the reasonableness and the feasibility of the components of the urban green space system planning and construction from the landscape,the ecological and the economic views ,Which are the essential points of the urban green space system.In addition to the Introduction in the first chapter and the Conclusion this article is divided into five parts.The first part is theoretical study. The present situation,the law and the trend of development in the urban green space system planning and construction are analyzed in this article from the landscape,the ecology and the economy three aspects. And the essential requirements of the urban green space system planning are discussed from the Landscape,the Ecology,the Landscape ecology and the Economics views.In the second part, the geographical background of the area were introduced, And the law of succession of the oasis in this area,the characteristics of urban and the situation of the urban green space construction are analyzed. On this base, the main problem of the urban green space planning and construction in this area are summed up.In the third part, After analyzing the natural and geographical characteristics in south of Tianshan, All the aspects of the urban green space planning and construction (except for the layout of green space)in the oasis of this area are given new definition from the landscape,the ecological and the economic three perspectives.In the fourth part, the layout of the ecological green space and the urban green space in this area are analyzed. What is the construction of the ecological landscape pattern of the green space in this area. Through dividing the structure of the urban green space planning and analyzing the culture of the green landscape in this area, Under the framework of the Landscape ecological security pattern, The ecological landscape pattern is established from the region and urban second-level in this area.In the fifth part, Taking the green space system planning and construction in Xayar County as an example and the earlier theoretical study is combined with practice, trying to rebuild planning and construction system in the green space system in Xayar County. And the needs of the nature in the urban ecology, the economy and the culture in this area are meted.
