你可能喜欢随着城市人口的增加,工业的快速发展,城市生态环境日益恶化成为城市可持续发展的瓶颈。城市森林在维持和改善城市生态系统,促进自然、经济、社会的和谐发展,谋求城市与环境的共同发展具有重大的意义和作用。城市森林建设评价是对城市森林生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用进行科学合理的评价。其目标是建立科学衡量城市森林建设的评价指标体系,对城市森林建设进行评价,为城市功能定位、城市可持续发展规划、政府决策等提供参考。本文根据洋浦经济开发区自身特点,遵循系统性、科学性、代表性、可操作性、可比性原则建立了洋浦经济开发区城市森林建设评价指标体系,采用层次分析法获得各层评价指标权重。根据建立起来的评价指标体系对洋浦经济开发区城市森林建设进行评价,结果表明洋浦经济开发区城市森林为0.628,其中结构指标、功能指标、景观格局指标、经济效益指标、社会效益指标及保护与管理指标分别为0.146、0.229、0.148、0.033、0.031、0.041。洋浦经济开发区城市森林建设较合理,基本能符合“新兴滨海工业区”城市定位应具备的城市森林体系。洋浦经济开发区城市森林可从以下几方面提高城市森林的生态环境服务能力：一是保护原有的绿化,减少城市建设进程中的破坏；二是提高数量指标,主要是提高工业区、居民区、道路绿化带等的绿化面积；三是提高质量指标,主要是选择适合的优良树种及合理的植物群落配置模式。树种选择以椰子树、榕树、马占相思、台湾相思等为基调的植物。本文建立了适应于洋浦经济开发区城市森林建设评价体系,对洋浦经济开发区城市森林建设进行全面评价。评价结果可为洋浦经济开发区“新兴滨海工业区”中长期建设规划提供参考,对国内、海南省其它城市特别是以工业为主导的城市森林建设与评价也有参考作用。
With the increase of urban population and rapid industrial development, urban ecological environment is deteriorating so as to hamper the sustainable urban development. Urban forest system is believed to help maintain and improve urban environment quality, in turn to promote of urban social and economic development as well as the harmonization between human beings and the nature in cities or towns.Status and planning of urban forest evaluation of urban development layout of forest ecosystems and ecological is the processes that formed and maintained by the natural conditions of human life and utility of scientific evaluation. The goal is to establish scientifically measured Construction in urban forest planning and development layout and evaluation system building on the status of urban forest planning and development and evaluation of the layout, positioning the city function, urban sustainable development planning, provide basis for government policy-making.This essay is based on Yangpu Economic Development Zone. Followed the systematic, scientific, representativeness, feasibility and comparability, Yangpu Economic Development Zone has established the principles of urban planning and development of forest status and distribution of building evaluation system using Analytic Hierarchy Process (AHP) the weight of each index.According to these established evaluation index system of the Yangpu Economic Development Zone Construction in urban forest planning and development layout and evaluation, the results show that the construction of Yangpu Economic Development Zone status and urban forest planning and development layout is 0.628, including structural, functional index, landscape pattern of indicators, economic indicators, social indicators and indicators of protection and management, respectively is 0.146、0.229、0.148、0.033、0.031、0.041. It is therefore concluded that the urban forest in Yangpu Economic Development Zone generally stands up to urban forest for a new coastal industrial zone.Yangpu Economic Development Zone urban forest can improve the following aspects of the ecological environment in urban forest service capabilities:Firstly, it could protect the existing green zone and reduce the urban construction in the pr secondly, it could increase the number of indicators, such as the function of improving the industrial area and residents’areas. Such as the green
thirdly it could improve the quality of indicators, mainly for the excellent choice of plant species and reasonable configuration mode. It is recommended that such tree species as Cocos nucifera Linn., Ficus microcarpa Linn.f., Acacia mangium and Acacia confuse Mer, could be selected as the tone species for the urban forest of Yangpu.The present study established an evaluation system including indexes and criteria for the assessment of the urban forest in Yangpu Economic Development Zone, which then was applied in practical evaluation activity. The results of the evlaluation study is believed of good value for the local government in their future urban forest development planning and implementation as well as to other cities in similar practices. The methodology and the index and criteria system developed in the present study are good references for urban forest evaluation studies elsewhere.
