Analysis Construction And Evaluation Of Urban Forest Landscape In Hangzhou Main City Zone

With the acceleration of urbanization, the problems of urban highlight, as an important component ofthe urban ecological system, urban forest receive more and more attention from people. As the deepeningof the research of urban forest, urban forest landscape study has high practical value. This paper analysesthe situation of urban forest landscape construction in Hangzhou main city zone in macroscopic view, andconstructs the comprehensive evaluation system of urban forest landscape in Hangzhou main city zone.According to the system, this research chose samples from followed five kinds of urban forest landscape:pointlike forest, linear forest, belt forest, planar forest, massy forest. Evaluating and analyzing the datefrom survey, measurement and evaluation assignment. The main conclusions are as follows:（1）Analyzes the situation of urban forest landscape construction in Hangzhou main city zone, fromtwo aspects: the construction of green corridor and the construction of different administrative area.（2）This article uses the method of describing factor to evaluate urban forest landscape in Hangzhoumain city zone, and constructs comprehensive evaluation system based on the Analytic Hierarchy Process(AHP) in Hangzhou main city zone from three function: landscape, ecology and Recreation, based ondescription of green looking ratio, seasonal aspect, forestform, ancient and rare trees, cumulation ofdominant plant, species diversity, resource utilization, air cleanliness, enter degree, recreation facilities,accessibility, service radius.（3）According to the comprehensive evaluation system of urban forest landscape in Hangzhou maincity zone, compare the scoring percentage between landscape function, ecology function, recreationfunction. Recreation function gets the highest scoring percentage, followed by ecological function, andlandscape function gets the lowest percentage. At the same time also compare the scoring percentage andcomposite evaluation index（CEI） between the five kinds of urban forest.In the five kinds of urban forest, massy forest’s scoring percentage in landscape function andecological function are both higher than the80%aim; Planar forest do its best in recreation function,reaches to90.63%, but other kinds of urban forest are similar; strip forest and linear forest’s scoringpercentage in landscape function are both less than61%, when pointlike forest, planar forest, massy forest all get more than75%; Pointlike forest gets higher scoring percentage in the three functions.The CEI of urban forest landscape in Hangzhou main city zone is0.71≤0.73780≤0.85, indicateurban forest landscape’s quality is preferably good. The CEI of massy forest is the highes（tCEI=0.92814）,indicate this kind of urban forest landscape’s quality is very good; Second is the CEI of planar forest（CEI=0.77057）, indicate this kind of urban forest landscape’s quality is preferably good; The CEI ofpointlike forest is better than linear and strip forest, are0.69302,0.64021and0.65708, indicate these threekinds of urban forest landscape’s quality is general.（4）Puts followed four Suggestions for urban forest landscape construction in main area of Hangzhou:pay attention to health care function, improve the quality of the forest, put culture into the construction,improve social participation.
