长江上游安宁河流域主要生态环境地质问题及其效应

Eco-environmental Geological Issues and Effects in Anning River,Upper Yangtze

通过对安宁河流域生态环境地质现状全面深入地调查 ,结合大量前人资料和多时段的遥感解译成果综合研究 ,作者从区域稳定性问题、水土流失、泥石流、滑坡、水土污染、矿山开采、重大工程活动等方面系统全面地分析了安宁河流域存在的主要生态环境地质问题 ,并分析探讨了其产生的生态环境效应 ,阐明了地质环境条件对生态环境的影响和控制作用。为安宁河流域的生态地质环境合理开发与保护 ,以及流域经济可持续发展规划提供了科学依据。研究成果表明 :安宁河并不安宁 ,流域新近构造活动强烈 ,泥石流、崩塌、滑坡、水土流失等多种外动力地质现象极为发育 ,不合理人类工程活动导致的生态环境地质问题也表现得十分突出 。

Having in-depth surveyed the eco-environmental geology of the Anning river,combin data and remote sensing information, the authors analyze the main eco-environmental geological issues including area stability,soil erosion,engineering activities,as well as their offects.Finally,we elucidate how the geo-environmental condiction control the eco-environment. The achievement offers for the comprehensive exploitation and protective programming of eco-geological environment in Anning river, and for the sustainable development of area economy.
