摘要
在概要地阐述有关地理信息系统缓冲区分析的技术支持、基本原理及算法后,就缓冲区分析技术应用于城市生态景观建设的效应评价及人类活动对自然生态景观的干扰程度分析进行了实例讨论.结果表明,天津卫津河河道整治绿化工程对沿线产生的生态效益影响范围是300m左右;采矿点必须设在距保护区2000m以外才能保证自然生态景观免遭人类干扰.由此可见,缓冲区分析技术在生态环境影响的评价方面具有相当显著的作用.
The application of the buffer zone analysis to assessing effects of urban construction and human beings' behavious on the nature eco-landscape was discussed with Weijin River and Panshan Scene in Tianjin as examples. The results showed that the greenbelt project along the Weijin River should be done in the area of 300 m or so, and the mining location must be selected beyond the nature reserve 2000 m to provent natural landscapes from human disturbance. Thus, the buffer zone analysis based on GIS will play an important role in the eco-environmental impact assessment.
