摘要
岷江上游是四川省乃至我国西南重要的生态屏障,由于自然条件和人为活动的影响,成为典型的生态脆弱区。通过选取反映该地区生态脆弱性的14个代表性指标,根据四川省和全国的对比结果拟定了相应的分级和评价标准,并采用模糊综合评价法对其生态脆弱度进行了评价,结果表明:该区域处于高度脆弱状态,应大力加强岷江上游生态脆弱区的整治。
The upper reaches of Minjiang River, which is an important ecological barrier of Sichuan Province and even the west of China ,has become a typical vulnerable area in eco-environment as a consequence of natural conditions and human activities.This paper chooses 14 representative indexes, establishes the corresponding grading and assessment criteria based on a contrast between Sichuan Province and the rest of China, and uses the fuzzy comprehensive assessment to evaluate the extent of eco-environmental fragility, with the result that this region is ecologically vulnerable.Therefore, it is imperative to enhance the renovation of the fragile eco-environmental area along the upper reaches of Minjiang River.
