| Recently urban pollution is serious, so urban living environment faced serious security problems. City dwellers are beginning to aware the importance of high urban greening quality of living environment. To assessment the urban greening quality of living environment can guidance theory in improving the quality of urban greening. We evaluated the ecological urban ecological greening quality of living environment in Guangzhou, and had established a green living environment of urban ecological quality evaluation index system.Part I: first, we explained the background and research significance. Secondly, we introduced the natural, social and economic conditions,the research content and research methods in Guangzhou.Part II: We introduced the theory of evaluation the quality of ecological urban green living environment.Part III: By processing remote sensing data, we got the greenbelt vector-graph to Guangzhou City, and then analyzed the greenbelt landscaping condition to Guangzhou City. The landscape quality is better in Guangzhou. For example, there is better the green space connectivity and the better transportation accessibility in Guangzhou. There is much different districts between green space accessibilities and transport accessibilities. We got the conclusion that landscape connectivity and landscape patch scale was inverted U-related. Guangzhou should increase inter-regional green building, reduce the differences between different zones.Part IV: we chose 24 typical residential green spaces and 12 typical parks, and made ecological analysis to these green spaces, in the main urban area. Park and residential green space plant diversity are relatively high from overall level, and the various indicators Joe blaze is rich grass, particularly in the new residential area vegetation diversity is very high. In new residential green space, the local species is too small, and there is the bad for ecology benefit. This trend is unsustainable. Evergreen and deciduous plant allocation ratio is suitable. Old city green areas have larger greening quantity and better eco-efficiency.Part V: The first step, we built an evaluation system; under the guidance of assessment construction principle of ecological urban green living environment and investigating the actual ecological urban green living environment situation in Guangzhou. we fixed 24 indexes which also result from studying of bibliography, consulting experts and scholars. Then these 24 indexes were divided into 11 quantitative and 13 qualitative indexes. The method of dividing these 11 quantitative indexes was based on laws and regulations and related research, and 13 quantitative indexes fixed by the satisfaction of the residents and fuzzy mathematics .Finally we determined the weight by AHP. We used this evaluation system to analyze the condition of the 4 parks and 4 residential green spaces for study in Guangzhou .The result reveal that Dongshan Park is 90.7 and Meihuacun is 89.4. Tianhe Park and Yuexiu Park are next to them. These results are in line with the satisfaction of the residents. The third step, we evaluated the quality of urban ecological greening of human settlements with evaluation system from administrative area .The highest score is 87.4 points in Tianhe District, and the lowest is 71.6 points in Liwan District. The satisfaction by urban residents showed that evaluation system was right. The results showed that green living environment of urban ecological quality evaluation system for the evaluation of the administrative level has a certain scientifice and practicality. The fourth step, we developed a user-oriented evaluation system with VB language. Part VI :the conclusion and discussion.there is better the ecotypes'green quality of living environment as a whole. The Luogang and Liwan District need strengthen green construction. We constructed the evaluation system with practical and theoretical significance. At the same time, this section pointed out the problems needed improved in the search. |
