岷江上游生态农业建设与可持续发展研究

Study on Eco-agriculture Construction and Sustainable Development of Upper Reaches of the Minjiang River

岷江上游地区属典型的高山峡谷区,气候干旱,土壤瘠薄,农业环境恶化,经济基础薄弱,农业增产和农民增收的幅度较小。由于特殊的地质构造、特定的自然地理环境及社会经济条件,岷江上游地区农业发展适宜走生态农业的道路,实施合理的资源利用和生态环境保护建设,使农、林、牧业良性循环,综合协调发展,实现生态、经济、社会效益的统一。

The primary characteristies of ecological agriculture is that it can greatly promote agricultural productivity, at the same time,protects the ecological environment. The upper reaches of Minjiang River lies in the upper reaches of Yangtze River, northwest of Sichuan province, and serves as one of the important ecological barries for the Yangtze River and the major water supplying area to Chengdu plain. However a series of ecologica environment problems have emerged because of the particular natural condition, massive lop and reasonless utilization of vegetation in recent decades. It no only has brought about many-side harm to soil, land and water resources, but also has formed a serious threat to the ecological environment. The serious ecologica environment problems has hindered the continuable social and economic development in the region. So, ecological agriculture is the outcome of the economic development and protection of the ecological environment in the upper reaches of Yangtze River. This paper, on the basis of latest survey data, analysed the background, current situation and features of the eco-agriculture in this region.
