The Analysis Of Landscape Pattern And Synthetic Benefit Of Urban Greenland System

City, as a high density habitation of human being, its environment situation is relative to the living standard of people . Urban greenland is one of symbols of urban civilization, it plays an important role in improving urban living environment.The article takes Korla as an example, analysis the landscape pattern and synthetic benefit of urban Greenland system. The main contents and research achievements are as follows:1,Analysis the landscape pattern of urban greenland system. Classing the Korla's urban Greenland at the beginning, based on Korla Greenland actuality and according to the function of Greenland, Korla's greenland is classed to five kinds included common greenland, path greenland, yield Greenland, courtyard greenland and defend greenland. Secondly, select the TM image of 2000, analyzing by patch for arcview of Arcview 3.2, the mainly conclusion is Korla's greenland landscape distributes non-uniform, Shannon Diversity Index is low .The human activity disturbance Greenland strongly ,the fragmentation of Greenland is high;2,In the factor of eco-benefit, the article adopted industrial oxygen-producting method, cost fee method ,manpower capital method ,fathering fee method and project-substituting method to calculate the eco-benefit in keeping carbon-oxygen balance ,absorbing poisonous gas , stagnating dust, measuring temperature, holding soil and water. Eco-benefit reached 18601630 RMB. Because short of materials and data, the thesis only reckoned a part of eco-benefit, and for the reason of Greenland area and green biomass different, in fact the benefit is more over than reckon.;3,In the factor of economy benefit, took the data of GDP,greenland area per capita,permanent assets investment of society and the number of workman as originality date .Setting up multi-dimensional regress model by econometrics and SPSS13.0, evaluate the contribution rate of greenland of Korla to economic enhancement;4,It's difficult to measure society–benefit of urban Greenland, this article use qualitative analysis, appraise the society benefit;5,At last according to the conclusions point out the existent problem in Korla's greenland construction and put forward some suggestion in greenland construction.
