The Study On Ecological Planning Of Urban Green Space System

With economic development of Shapingba District quickly, a series of ecological environment destruction eased by the rapid expansion of the city have become a factor limiting the further development of the urban district and the further improvement of living standard in Shapingba District. It's an urgent task to compile a scientific and sound urban green space system Planning.Since 1990's,the idea of"ecological garden"has increased people's awareness on the functions and effects of gardens,and is improving city environment and maintaining ecological balance of a city have become an important function of urban green space.

With the dual purposes of improving city ecological environment and satisfying the needs for sightseeing and recreation, the principle and indices of the ecological planning of green area system, structure layout of green space and greening design in Shapingba District were studied. On the basis of the analytical results,the analysis on the economy, environment and society benefits of green space in Shapingba District was worked out..In actual planning,a green network ecological layout based on natural mountains and rivers, park green spaces and corridor green areas were constructed,mainly the setting of city parks,ecological corridor sand protected green areas was investigated,an idea to construed sightseeing belt around the city based on natural mountain vegetations and cultural historic sites was set forward. In addition, in light of current status in Shapingba District, resistance planning of green area tree species and suburban tree species planning in Shapingba District has also been attempted. The dissertation can provide theoretical guidance and planning references for the planning of city green space system of Shapingba District, and can provide suggestions how to improve city constructions and living environment in Shapingba District.
