| The advice of "Let the forest into the cities, Let city embraced forest", supposed in the First Forum of China Urban Forest, now is a new ideas of the protection of urban ecological environment, improving the image of the city and comprehensive competitiveness, and promoting the sustainable development of the regional economy. In the construction process about urban forest that would involve a series of scientific problems because of the urban forest involves various subjects, fields, sections. in this complex system engineering to solve the problem that how to judge the urban forest on pattern, community structure is reasonable, the number of urban forest whether to satisfy construction, the ecological function whether efficiency, the key to solving this problem is a set of scientific and reasonable comprehensive evaluation index system, not only can determine the situation of the construction of the urban forest for urban forest, still can provide scientific basis for future construction. Urban forest comprehensive evaluation is the foundation of urban forest planning design and construction management, the scientific and rational evaluation index is both urban forest construction level, but also is a ruler to lead the urban forest development.This paper referring to relevant urban forest research results and practical experience, with China's status and trends of urban ecological landscape and urban forestry, urban green space development, from different aspects and angles of urban forest concept, scope and function to study, understand urban forest concept, scope and function, make selecting urban forest comprehensive evaluation index system more guidance and pertinence, At the environment level in the city,how to evaluate urban forest comprehensively directly related to urban forest construction mode.According to the climate, land and social, economic and urban forest construction situation and other urban forest impact factor, according to different types of regional studies the forest ecological environmental conditions and development direction of the main cities in China, with SPSS software,using the factor analysis and cluster analysis to classify the national urban forest types and comprehensively appraise features, provides the basis for regional urban forest evaluation system, structure analysis, classified the functional types. Urban forest in comprehensive evaluation index system based on the basic theory of construction of urban forest in Wuhan city, as the research object, full consideration Wuhan urban forest impact factor, based on the guiding principle of comprehensive evaluation index system of urban forest, using Delphi method and analytic hierarchy process (AHP), determines the comprehensive evaluation index system of urban forest, combined with the construction of Wuhan city forest of the index system each index factor analysis, combined with the qualitative and quantitative analysis, the research system is more scientific and reasonable.In this paper, the process of selection index has fully considered the regional urban forest construction, preliminary studied the impact factor of urban forest, comprehensive evaluation index system is established more targeted, guidance and representative for urban forest, comprehensive evaluation index system is established to provide a new perspective. |
