摘要
3S技术将生态环境影响评价由定性评价转向定量预测,为建设项目生态影响评价提供了新的研究途径。文章以灌阳至平乐公路建设项目为例,制作了公路沿线生态敏感区空间分布图。对高速公路建设前沿线景观和建设后沿线模拟景观进行分类和制图,并进行高速公路修建前后景观指数计算,分析了高速公路修建前后景观格局的变化。结果表明:高速公路的建设将导致景观格局的改变,景观异质性增加。
The 3S technology offers a new approach for assessing the ecological impact,could turn the qualitative assessment into quantitative prediction. This paper investigates the application of 3S technology in ecological Impact Assessment by the case Guanyang- Pingle highway. The Spatial distribution map of Ecological sensitive area were charted. The landscape of the Guanyang- Pingle highway were classified and charted and changes in the landscape before and after the highway construction were analyzed. The result showed: the landscape pattern will change after the highway construction. the landscape heterogeneity increased.
