摘要
岷江上游是成都平原经济区的生态屏障和水源生命线。在生态环境地质调查的基础上,选定了岩性、构造、地形地貌(海拔高度)、植被覆盖生态区、地表水、地下水、土壤类型及地质灾害等8个评价因子,采用模糊数学的方法对岷江上游生态环境地质质量进行了评价,评价结果与研究区的实际情况基本相符。
The upper reaches of Minjiang River serves as ecological barriers and the major water supplying area to the economic zone of Chengdu plain.Based on ecological environmental geological survey,it adopts fuzzy mathematic method and selects eight factors of lithological property,geological structure,benthonic terrain,plant cover ecological areas, surface water,groundwater,soil types and geological hazards to evaluate the quality of ecological environmental geology in the upper reaches of Minjiang River.The result is basically compatible with the reality of studied area.
