The Study Of Ecological Greening Evaluation Of Yaohai Industrial District In HeFei City

With the acceleration of industrialization, the construction quality of urban green system has increasingly grown influence residential environment, and the environment green quality of industrial district even directly affects the quality of life. In the recent years, the malignant feedback and destruction of industrial pollution to environment become evident day by day. People’s environmental consciousness has gradually strengthened, and much more attention has been paid to the construction of the green system in industry districts. However, the acquaintance for the establishment of evaluation system of ecological greening is still not in place, and the relevant study was imperfect. Therefore, the further study about enhancing evaluation system of ecological greening in industrial district is necessary.In this paper,10 typical factories has been selected in Yaohai Industrial District of Hefei City, such as AnHui LiHua KeJi, ZhongSheng footwear industry, LvBao group, YaoHai GangJieGou, Hefei seiko textile, BaiDa group, Tedelon clothing, Peak clothing,HengAn group, Garment processing park. We study the present greening condition of industrial district qualitatively and quantitatively by field investigation combined with questionnaire survey. Based on the work, we establish an evaluation system of ecological greening for Yaohai Industrial District which could also provide the technical guidance and reference for the evaluation system establishment of ecological greening to other industrial park. The concrete content includes the following aspects:1. The research progress is reviewed, and the study of the predecessors is concluded and summarized. The basic information of Yaohai Industrial District, and the main method and technical route of this research are introduced briefly.2. The evaluation index of the evaluation system of ecological greening is determined by Analytic Hierarchy Process (AHP), mainly including:1 target layer,3 criteria layers and 10 index layers. The target layer is the results of comprehensive evaluation of ecological green industrial park; the 3 criteria layers are ecological function, landscape function and cultural function; the 10 index layers has included ratio of green space, green quantity volume rate, plant diversity index, plant adaptability index, plant morphology, plant color, seasonal aspect, plant hierarchy, awareness, satisfaction.3. Through the determination of each evaluation index, the results show that the ratio of green space of Yaohai Industrial District is 25.39%, it still exists a certain gap when compared with the national prescribed industrial standards 30%. Among the surveyed factories, only 30% factories reach the standard. The factories which have much more workers present a relatively less per capita green area, particularly for Hefei seiko textile. When the factories’ areas show great disparity, comparing the total amount of green can’t completely illustrate the problem, especially in the case of LvBao group. Taking all these into consideration, based on the statistical quantity of green, we introduce green quantity volume rate as another measurement index.4. The study investigate 52 families,83 genera and 93 species of afforestation plants, including 36 arbor species,34 shrub species,4 liana species,19 ground-cover plants.5. We should consider the shape of tree species, color, seasonal aspect when selecting greening tree species, besides that, we also pay attention to the configuration of halosols deserts, to create the variable colorful seasonal greening effect.6. The evaluation system of ecological greening is applied to Yaohai Industrial District, getting an average socre of 3.78 points. Within each evaluation indexes, the scores of season phase and plant optimum nature are relatively high.It indicate that we should attach the great importance with natural characteristics of plant in the process of greening, such as seasonal aspect and plant adaptability index.7. The greening construction problems of Yaohai Industrial District at the present stage are summarized, and relatively reasonable greening suggestions are put forward.
