The Research About Plant Landscape Evaluation Of Wu Li He Park In Shenyang Based On AHP

Waterfront green space is of significance in urban public open space,it is an important part of urban public space.The landscape of waterfront green space is the green landscape with regional characteristics.In the development of plant landscape,it is more and more important to research waterfront park plant landscape.The AHP analytic hierarchy process was used in this paper uses to construct the waterfront plant landscape evaluation model,the combinative methods of qualitative index and quantitative index were used to evaluate plant landscape of Wu Li He Park in Shenyang.In the evaluation model,quantitative index was composed of four indicators such as diversities of species,plant ornamental characteristics,structure in life and landscape sequence.Qualitative indicators refer to the coordination with plant and whole environment,the concordance with hard landscape and habitat,and accessibility of plant landscape.The evaluation model of waterfront plant landscape was established based on the combination of qualitative and quantitative indicators.The quantitative index of landscape diversity and the quantitative value of qualitative index were calculated by Simpson index formula,and the comprehensive evaluation system of waterfront plants was used to evaluate the plant landscape of Wu Li He Park in Shenyang.Through the evaluation and analysis of park landscape of Wu Li He Park in Shenyang,we came to the conclusion that macrophanerophytes,deciduous species and broad-leaved species mainly comprised the plant communities in the park.In plant configuration,there was less sample land with rich space hierarchy,some of which could exhibit the art of plant landscaping.Most plant landscapes were combined with trees,shrub and grass,thus,high and low,thick and thin landscape space was formed.The plant species were rich in plant configuration,plants with different ornamental characteristics were matched.The numbers of seasonal plants were fewer.There were few kinds of plant species with seasonal variation in native tree species whose application was even less in the actual landscape configuration.In spring and summer,the landscape was highly ornamental,various flowering tree species had different colors,whereas some of the sample lands was not highly ornamental in autumn and winter.According to the conclusion,some suggestions were put forward for the plant landscape of Wu Li He Park in Shenyang.We should further excavate and apply the tree species with historical and cultural characteristics.We should strengthen the diversity of community forms,enriching the sense of hierarchy and strengthening the maintenance and management of plants in the configuration of the waterfront plant landscape,.
