A Reaserch Of Xindu Distrct Greenland System's Planning Based On Urbun's Comprehensive Enviroment

Urban ecological environment construction is one of the essential features of modernized urban construction, while the urban gardening is its core problem. To improve urban green land system's planning and construction, and make it play its special function and role sufficiently in cities, it is necessary to understand the functions and roles of urban green land. For scientific research, it has now become a direction to plan urban green land scientifically which is based on the functions of urban green land. Scientific and rational planning of green land will make a crucial effect on the improvement of urban environment.Located in the central of Sichuan Basin, northern suburb of West Sichuan Plain hinterland—"Land of Abundance", Xindu District is known as the "Tianfu Pearl" and the "fragrant city". Being the subtropical humid monsoon climate and evergreen broad-leaved forest, its gardenning green construction will have a good representation and model for small towns under this particular climate and vegetation. Therefore, this paper gives us some detailed investigations and analysis of Xindu's comprehensive environment (including water environment, atmospheric environment, noise environment, thermal environment, recreation environment), and the current Xindu District green distribution. The major research conclusions are as follows:1,the uneven structure layout of green space in Xindu District. Although nowdays the total amount of green area is relatively large, the distribution is uneven, as a large number of green areas are collected in the new city, while in old towns there are only two Culture Park-Guihu Lake Park and Baoguang Si Park.2,a few green lands on both sides of the river in Xindu District. Even though there are some protective green on both sides of river, the visual environment is messiness, fragmentation, and lack of integrity.3,road virescence's integrity and continuity is inadequate. Sequence is not so good. The road virescence gap between the old and new city is relatively large. Tree species selection has no uniformity and regularity. 4,enough attention to improve the urban ecological environment greenbelt construction has not been given. Virescence construction and urban integrated environment structure are not enough yet. An unified protection reminder has not been established.In order to solve the green land problems, after taking some investigations and the theory and the Xindu District's characteristic into consideration, some new ideas on Xindu District green land system planning which is based on Xindu District comprehensive environment are proposed in this paper.This plan can provide some directions to establish the Xindu's different kinds of development plans of green land and the layout of various types of garden's green land, so as to get the final goal of protecting and improving ecological environment, optimizing the urban living conditions and promoting urban sustainable development.
