基于规划支持系统的环境影响评价

Environmental impact assessment based on planning support system

如何在土地利用规划过程中考虑环境影响是土地利用规划中的一个难点问题.在定义活动、影响域、功能区、敏感度等概念的基础上,详细论述了土地利用规划支持系统(strate-gic tool for integrating environmental aspects in planning procedures,STEPP)将环境影响融入土地规划设计的过程.该系统是在ArcView GIS二次开发语言Avenue上开发的规划支持系统,可以方便规划相关人员在系统平台上进行信息交互,并在空间上直观、定量地表现规划过程中的环境影响及其变化.以荷兰埃德和维纳多市之间的城乡结合部为研究区进行案例研究,结果表明,该系统的定义和评价过程能较好地将环境影响融入到规划设计过程中,适时、直观地反映规划措施对环境的影响,方便了规划参与者参与规划过程,为决策者制定科学规划提供了依据.最后,对该系统如何应用于我国的规划环境影响评价提出了建议.

How to assess environmental impact is one of the keys in land use planning.This article described in detail the concepts of activities,impact zones,functions,and sensitivities,as well as the development of STEPP（strategic tool for integrating environmental aspects in planning procedures） based on Avenue,the secondary developing language of ArcView GIS.The system makes it convenient for planning practitioners exchanging information,and can spatially,visually and quantitatively describe environmental impact and its change.In this study,the urban-rural combination area located between EDE and Veenendaal of the Netherlands was taken as case,and the results indicated that the environment was incorporated well in the planning procedure based on the concepts,and could also demonstrate the effects of planning measures on environment spatially,explicitly,and in real-time,facilitating the participation of planning practitioners and decision-making.Some proposals of how to promote STEEP application in China were suggested.
