In this paper,analytic hierarchy process( AHP) was used to select 13 specific indicators to construct the evaluation system of woody landscape plant maintenance effectiveness from 3 aspects of ornamental,growth status and soil condition combined with qualitative and quantitative analysis,with the aim to explore an effective and scientific method to evaluate the effectiveness of landscape plant maintenance.展开更多

The comprehensive evaluation indexes of landscape include forest coverage, biodiversity, stability, soil erosion, environmental quality, availability, scientific research characteristic, economic benefits. Using AHP (analytical hierarchy process), determine the grade of ecological evaluation factors and the weight of evaluation index and calculate the CEI (comprehensive evaluation index) on ecological evaluation. Evaluation results showed that the area CEI was 0.714 225, a better quality of the ecological level, but biodiversity indicators was the lowest. To sum up, it was difficult to maintain ecological restoration effectiveness and process but also guarantee a good biodiversity in the add-hot valleys. We must reasonably arrange the alien species and the native species, in order to obtain a stable and sustainable eco-system.展开更多

Besides,it calculated the ideal solution and closeness degree of matrix using TOPSIS,and established the evaluation method and preference method for plant landscape in residential areas. The results show that the indicators of seasonal variation,environmental benefit and per capita green space mattered most in the landscape evaluation of residential areas. The richness of flowering plant is weak in the landscape evaluation. From the comprehensive evaluation of residential areas,Nyingchi Garden District and Xingfu District have excellent plant landscape,Jialong Garden District and Shangcheng Garden District have general plant landscape,and Sun City District and Niyang Garden District have poor plant landscape.展开更多
