Study On The Ecological Assessment Of Community Green Infrastructure

Shortage of resources and environmental pollution become increasingly problem to our country, for these reasons to build an ecological civilization has been written as a principle decision in our new five-year plan and the “Green Infrastructure” is an important part of it. Most of our research is forced on regional scale, the study on the neighborhood green infrastructure starts late and only in small area. In the form study they usually focus on green rate, the ratio of per capita public green area of bushes and trees and public green space ignoring the eco function of the green infrastructure. In this paper, we aim at the imperfect community of Green Infrastructure Assessment Index, combine with some international criteria and our situation gets the evaluation. Based on this evaluation we made some questionnaires to make it better, after this we make a reclassification on the principle of ecology. At last we test it on the neighborhood.We select nine internationally recognized infrastructure assessment systems, and filter the system of indicators based on frequency, importance and relevance of the principles of green infrastructure and community ecological assessment, at last 35 indicators come out.Through questionnaire survey and interviews we complete the indicators, mainly interviews are planning designers, landscape designers, ecology experts and local people living in the community. According to feedback from different g roups we made the final evaluation index.We classified the 21 index according to research principles of landscape ecology, ecological security pattern theory, the theory of landscape heterogeneity, ecological performance principle and relevant sociological theories, the ecological security pattern and the eco performance indicators are also used to help reclassification. By reclassification the index in the ecological assessment process, we can apply it on green infrastructure for community planning and im provement.By studying we establish a method for the quantitative assessment of community green infrastructure ecological assessment indicators. We considering the ecological communities from different aspect to provide a basis for our ecological planning and design of community green infrastructure. This indicator improved the principle of community planning and made a sample for urban ecological environment construction in China.
