| This paper based on the survey of the citie’s urban forest current situation, using the beauty degree evaluation method(SBE) for different types of urban in-forest landscape and out-forest landscape evaluation, through the evaluation to select the SBE beauty degrees higher score town forest community types, analysis the main influencing factors of different types of urban forest landscape, the build the different types of forest landscape model, analysis the relationship between the main constitutive elements and the degree of urban forest community beauty; Selecting typical urban forest community and analyses ecological function, select the best ecological function community structure, combining beauty degree evaluation end get optimal allocation model of different community types, urban forest planning layout, provide the technical support for the urban forest planning layout, tree species selection and Community structure regulation.In zhucheng, chose the different types of forest community landscape: three kinds of mountain forest landscape types, eight kinds of riparian forest landscape types, eight kinds of village forest landscape types, and fifteen kinds of road forest landscape types. The main results were as follows:(1) In the mountain forest landscape, the highest beauty score was the Chinese chestnut forest, the beauty of the in-forest landscape model was:SBE =-1.059+0.315×x6 +0.095×x9. The main factors which influence the mountain forest’s in-forest landscape were tree abundance(x6) and the average tree height(x9). The main factors which influence the mountain forest’s out-forest landscape were canopy texture and canopy level.(2) In the riparian forest landscape, the highest beauty score was the beautiful scenery of the poplar riparian forest, the beauty of the in-forest landscape model was: SBE =-0.389+0.109×x8 +0.236×x13. The main factors which influence the riparian forest’s in-forest landscape were undergrowth coverage(x8), average under branch height(x13); The beauty of the out-forest landscape model was: SBE =-0.263-0.424×x3-0.494×x6+1.055×x9. The main factors which influence the riparian forest’s out-forest landscape were plaque distinguishable(x3), trunk clarity(x6), color brightness(x9).(3)In the village forest landscape, the highest beauty score was the beautiful scenery of the poplar village forest, the beauty of the in-forest landscape model was: SBE =-0.266+0.253×x10+0.053×x13, The main factors which influence the village forest’s in-forest landscape were crown density(x10) and average tree height(x13); The beauty of the out-forest landscape model was: SBE = 4.717-1.037×x4-1.804×x8. The main factors were patch shape(x4) and canopy level(x8).(4) In the road forest landscape, the beauty of the in-forest landscape model was: SBE =-0.301+0.107×x1+0.298×x4+0.088×x5+2.726×x9-1.746×x10-0.124×x13+0.525×x14. The main factors which influence the road forest landscape were color richness(x1), the life(x4),growth(x5), undergrowth coverage(x9), crown density(x10), average tree height(x13), average under branch height(x14).In different types of urban forest landscape selecting several kinds of typical forest community types, investigation and analysis its ecological service function. Measurement indicators are: air temperature, air humidity, solar radiation, soil temperature, soil moisture, soil compactness, air negative oxygen ion, PM2.5 and PM10. Each forest including reunite, the forest, the forest three repeat, finally it is concluded that each of the different types of ecological service function best community.Based on the above the beauty degree evaluation of different types of forest community, to set up the landscape evaluation model, on the basis of the analysis of ecological function, puts forward a kind of typical plant configuration optimization model respectively to the mountain forest landscape, riparian forest landscape, village forest landscape and road forest landscape from plant selection, it is the innovation point in this paper. Ecological function in the construction of the forest also has a very important role in the process, it should be paying attention. Combination of beauty and ecological service function, can better for provide the technical support for the urban forest planning layout, tree species selection and Community structure regulation. |
