Evaluation of Plant Landscape in Residential Areas Based on AHP and TOPSIS

Taking 6 residential areas in Nyingchi of Tibet as research objects,from aesthetic effect,ecological function and leisure service,this paper established the evaluation indicator system for plant landscape in residential areas using AHP,and calculated the weight of indicators using the judgment matrix. 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.

Entropy Method Based Evaluation for Plant Landscape in Tourist Scenic Spots

Taking five scenic spots in southeast region of Tibet as research objects,this paper calculated the weight of plant landscape evaluation system by entropy weight method,and compared the plant landscape in scenic spots from aesthetic effect,ecological harmony and service functions. The results show that the rank of the comprehensive attributes from high to low is as follows: Nanyigou,Lulang Forest,Kading Mountain Waterfall,Yarlung Zangbo Grand Canyon,and Basomtso Lake.

Evaluation of Regional Characteristic Landscape along the Commercial Pedestrian Street Based on AHP:A Case Study of Dongpo Bund in Huangzhou

Based on investigation and literature collation,the evaluation factors of regional characteristic landscape along the commercial pedestrian street were extracted,and the evaluation system of regional characteristic landscape along the commercial pedestrian street was established by the AHP method.The regional characteristic landscape along the commercial pedestrian street is the first-level index,including four secondary indexes of regional characteristics of road landscape,regional characteristics of plant landscape,regional characteristics of architecture and sketch,and spatial landscape experience,as well as 17 three-level indicators such as road environment landscape coordination,uniqueness of road markers and road landscape recognizability.The reliability of the evaluation system of the regional characteristic landscape along the commercial pedestrian street in Dongpo Bund was proved.The importance sequence of road landscape level,spatial landscape experience,landscape visual effect and plant landscape characteristics in the regional characteristic landscape was obtained,and it is closely related to users’ satisfaction.According to the problems found in the survey,suggestions on the transformation of the regional characteristic landscape along the commercial pedestrian street in Dongpo Bund were put forward to provide reference for the transformation and improvement of regional characteristic landscape along similar urban commercial pedestrian streets.

Landscape Ecological Evaluation on the Artificial Forest of Leucaena leucocephala——Taking the Example of Xiaokua Hill of Yuanmou

Based on the theory of ecology, this article conducted a landscape ecological evaluation on Leucaena leucocephala artificial forest in the add-hot valley, Yuanmou Xiaokua hill, using a combination method of qualitative analysis and landscape comprehensive evaluation. 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.

Research on the Evaluation System of Woody Landscape Plants Maintenance

The maintenance management of urban landscape plants play an important role in bringing their landscape and ecological functions into full play. 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.

Investigation and Configuration Analysis of Aquatic Plants in Chengdu Wetland Parks

To find out the current situation and configuration of aquatic plants in landscape water of Chengdu wetland parks,sample-plot survey of aquatic plants in landscape water in the built wetland parks of Chengdu and urban parks was conducted.The results showed that there are 41 kinds of aquatic plants in the research region,belonging to 23 families.They are mainly hygrophyte and emergent plants,while floating and submerged plants are rarely used.Configuration of aquatic plants is mainly composed of emergent plants,supplemented by floating-leaved and submerged plants,and water landscape is rich.Then,configuration of aquatic plants in wetland parks was analyzed from the ecological function,landscape construction and other aspects,to provide the reference for plant configuration of urban wetland parks.

Optimization of Urban Ecological Network Based on MSPA-MCR Model: A Case Study of Jingzhou City

As a key carrier supporting urban ecological health and living environment quality,urban ecological network is a key focus of current urban green space research.Jingzhou City of Hubei Province is taken as the research object.Relying on GIS technology platform,MSPA method is used to analyze the landscape pattern of Jingzhou City.On this basis,the landscape connectivity evaluation method is used to accurately identify and extract the source areas with important ecological value in Jingzhou City.Then,the normalization method and weighting method are combined to create a resistance factor evaluation system to construct the resistance surface.Based on the MCR model,the ecological network of Jingzhou City is successfully constructed,and targeted spatial optimization strategies and development suggestions are proposed.
