Study on Environmental Amenity of Changchun Based on Regression Analysis

Abstract:

Because of the continuous deterioration of urban ecological environment and the increasingly scarcity of comfortable environment, amenity became the core goal of human residence and urban development. To study the environmental amenity of Changchun, datas of different sources and scales were integrated and processed synthetically by taking GIS as technical means and the method of Principle Component Analysis as the methods to obtain the weights of the impact factors. The general score of the environmental amenity of the study area was 0.415 and the areas with higher scores than the average level accounted for 39.85%. Meanwhile, the amenity satisfaction scores of the 46 streets were received by the sample survey of the resident subjective satisfaction of the study area. The functional relationship between the subjective satisfaction score and the objective indicators were obtained by the regression analysis method. The results showed that the factors contributing greater to improve the resident subjective satisfaction were the vegetation cover and the proximity to the cultural facilities. Also, a quantitative reference to improve the subjective satisfaction of the environmental amenity was provided in the new urban environmental conditions of the future.
