| Based on theories of forest ecology and systemic science and planning of landscape forest, and according to the consisting of basic scenic spot relict aesthetic forest plots investigation data, community structure of scenic spot relict aesthetic forest and vegetation characteristics was analyzed, as same time the index of compatibility of scenic spot relict aesthetic forest was constructed. Normal analysis and isometric group method were used for determining evaluation index. AHP was used for determining index weight. According to survey data, The grade of scenic spot relict aesthetic forest was determined to four vegetation communities of evergreen and deciduous aesthetic forest, scenic spot relict deciduous aesthetic forest, scenic spot relict shrub and small tree aesthetic forest and scenic spot relict evergreen aesthetic forest. Finally, modification technology of the scenic spot relict aesthetic forest was studied, and the transformation planning was proposed, and taking the MuRrong pavilion of scenic spot relict aesthetic forest for example. There were some research conclusions:(1) Structural characteristics of four vegetation communities was analyzed about evergreen and deciduous aesthetic forest, scenic spot relict deciduous aesthetic forest, scenic spot relict shrub and small tree aesthetic forest and scenic spot relict evergreen aesthetic forest.(2) The total number of species manifested as the scenic spot relict deciduous aesthetic forest> the evergreen and deciduous aesthetic forest>the scenic spot relict evergreen aesthetic forest>the scenic spot relict shrub and small tree aesthetic forest. Seedlings of each types tree, based on analysis of species important value in shrub layer, was rare, do not both play important position, Seedlings tree of Ulmus macrocarpa and Locust were found in the shrub layer of the scenic spot relict evergreen aesthetic forest, which important value was over 2%. Constructive species, which success toward to climax community, the scenic spot relict evergreen aesthetic forest in low mountain of Beijing, was deficient. Diversity index, evenness index and richness index were compared about four types of the scenic spot relict evergreen aesthetic forest. Changes were almost consistent about diversity index. Evenness index of scenic spot relict deciduous aesthetic forest was the maximum, and evenness index of evergreen and deciduous aesthetic forest was the minimum. All kinds of index were almost equivalent about the scenic spot relict shrub and small tree aesthetic forest and the scenic spot relict evergreen aesthetic forest. T-JSW was represented that the scenic spot relict shrub and small tree aesthetic forest>the scenic spot relict deciduous aesthetic forest>the scenic spot relict evergreen aesthetic forest>the evergreen and deciduous aesthetic forest, richness index of T-JSW and T-Jgi was different, the evergreen and deciduous aesthetic forest was both the minimum on richness index of T-Jsw and T-Jgi. (3) Concept and content of the scenic spot relict aesthetic forest was explained. Evaluation index system of the scenic spot relict aesthetic forest, which included target layer, rule layer and index level, was initially built by collecting information and data in low mountain of Beijing.(4) The general ranking of index weight about evaluation layer on the scenic spot relict aesthetic forest was AP= (0.1375 0.1125 0.0374 0.0202 0.0354 0.0171 0.0165 0.0191 0.0168 0.0202 0.0221 0.0156 0.0295 0.0494 0.047 0.0635 0.0901 0.0999 0.0874 0.06627)According to the Statistics, the second scenic spot relict aesthetic forest was the most, make up 35% of total, the Non- scenic spot relict aesthetic forest and the first order scenic spot relict aesthetic forest were the minimum, make up 7% and 8%, the third scenic spot relict aesthetic forest make up 27.5% of total plot.The evergreen and deciduous aesthetic forest was the first order scenic spot relict aesthetic forest, the scenic spot relict deciduous aesthetic forest was the second scenic spot relict aesthetic forest, the scenic spot relict shrub and small tree aesthetic forest was the first order scenic spot relict aesthetic forest, the scenic spot relict evergreen aesthetic forest was the second scenic spot relict aesthetic forest, the scenic spot relict aesthetic forest was the first order scenic spot relict aesthetic forest.(5) Starting with principles and objectives of the transformation of the scenic spot relict aesthetic, and based on site condition, community characteristics, recreational function and vision of landscape quality, Species was reasonable choice, four transformation of the scenic spot relict aesthetic forest were proposed, which were consist of four levels about design of prospect, design of close-range and design of sightseeing platform peripheral Areas.Technical measure of the scenic spot relict aesthetic forest was proposed, specification requirements of seedling, dispensing seedling, modification measures and transformation construction points were all detailed explained.(6) The transformation planning was proposed about MuRrong pavilion of the scenic spot relict aesthetic forest, which offering the realistic basis for transformation of the scenic spot relict aesthetic forest. |
