Research On Visible Green Index Evaluation Of High Density Urban Area On Macau Peninsula

The city not only has the natural attribute, but also has the social economic attribute. It is a highly artificial environment. Urban green space has a great value to urban construction and development. It plays an important part of urban natural elements and important ecological basis for sustainable development of social economy. With the rapid developing of urbanization, it is inevitable that there will be more high density cities and urban areas. How to evaluate and supervise the construction of high density urban greening is an urgent problem to be solved.The visible green index measuring method was usedin this articles to investigate the typical high density urban areas of the Macau peninsula sufficiently. The main research includes: the relevant theoretical research for visible green index and the advanced measurement methods and research direction of visible green indexinother country.The hierarchy of visible green index in High density urban. Status quo of the Macau peninsula and visible green index. The analysis of visible green index influencing factors and general influence law, and the promotion strategy research about visible green index and model design. The main conclusions are as follows:(1)When visible green index lower than 7%, people feel very unsatisfied for urban greening construction. Visible green index is between 7% and 15%, people think that the urban environment greening construction is bad; If visible green index is higher than 15%, the afforestation is "qualified" and people feel good; Visible green index is higher than 30%, the residents were satisfied with the environment greening construction.(2)Through the analysis of the dateabout Macau peninsula city Visible green index found that urban visible green index overall qualified, but rendering the north-south high, intermediate low distribution.Visible green indexare changes greatly between observation points and observation area. The visible green indexin Blocks are poor continuity, the visible green index in historical block are not high.(3)Analyzing the influence factors of visible green index. The factors that surrounding observation points of the visible green indexmay affectthe visible green index should be considered, such as the greening rate, the greening coverage rate, population density, buildings density, the number of trees, etc. Usingthe software of SPSS19.0 analysis of correlation between these factors and the averagevisible green index.Data reflect the number of trees, the types of plants for the influence of visible green index is bigger. The more abundant, the combination of the plant and visible green index is higher.(4)The research of strategies about puts forward the promotion potential of Macao Peninsula's visiblegreen index, thepromotiontarget and the ways of improvementwhich is operability. The way of visible green index'simprovement approaches include:(1) developing the urban greeningoverall;(2) greening the remaining spacerefinedly;(3)promotingtheurban constructing and urban greeningcooperatively;(4)developingthe vertical greeningextensively,(5) developingthe district greeningpublicly;(6)managing and controllingthe green qualitystandardly. At last, the method is applied to the actual site of Macao Peninsula, andcarried out the model optimization.The innovation of this paper choosing Macau peninsula, the high density urban area, as the research object. Exploring the high density urban visiblegreen index measurement method, the key researchesarethe hierarchyof visiblegreen index and the visiblegreen index of impact factor. Put forward the high density urban visiblegreen index promotion potential and the ways to fill the blank of domestic related research.
