Plant Landscape Evaluation Of Park Green Space In Changchun City

With progress of the time, development of the economy and enhancement of the people's environmental awareness, people living in the city are more and more eager for a good living space and the exquisite living conditions. Park green space in the city plays as a important role in improving the urban environment, providing a leisured amused entertaining space for the people.Chang Chun, situated at the northeast center, is the first batch of the forest city confirmed by our country. Landscape greening in the city has a particular characteristic, especially in core forest land of the urban forest construction-park green space. Therefore, study on urban park green space has a important significance not only to Chang Chun's greening construction itself, also to the other city in the north.This article takes eight typical urban parks as the main investigation object, including the Nan lake Park, Zoological and Botanical Park, Chang Chun Park, Chao Yang Park, Victory Park, Children Park, Peony Garden, Flower of Apricot Village. Base on the present situation investigation and Statistic, We summary four kinds of green spaces structure in the park green space, including the forest land class shrub grass class sparse forest grass class and vicinity of water class, we select four typical forest land class green space, with the area of 20×40m;three typical shrub grass class green space, with the area of 20×20m;three typical sparse forest grass class green space, with the area of 40×40m;three typical vicinity of water class green space,with the area of 30×30m. We take the investigation on the four kinds of green spaces, obtaining the typical plant arrangement model of the four kinds of green spaces, analysing the present situation analysis of Chang Chun urban park green space plant arrangement.Applying basic principle of ecology botany landscape esthetics and the environmental science, we will scientifically establish the park green space plant landscape evaluation system, reasonably ascertain various importance indexes and make it mathematical quantification, obtains the landscape evaluation index weight by the analytic hierarchy process, to establish the AHP model of Chang Chun park green space plant landscape evaluation. According to the AHP model of Chang Chun city park green space plant landscape evaluation, we evaluate the four kinds of typical park green space in every park, analyze its landscape characteristic, and put up the arrangement and the class by the landscape quality index, and analyze the reason of landscape quality difference. Based on the plant landscape quality index of four kind of park green space structure, we establish the AHP model of Chang Chun park green space landscape evaluation, obtain the result of landscape quality evaluation in each park, and set up the arrangement and the class to them. The result will provide the ideas and thesuggestions on the construction of urban park green space in the future.
