近三十年来金沙江流域生态环境变迁研究综述

金沙江生态系统多样复杂并存。历史上,生息在该流域内的各民族生计方式都能确保地表相关生态系统的稳定,生态环境一直良好。其后随着西南及西藏局势的变化,中央王朝加强了这一地区的统治,由于开发方式失当,部分地段出现了生态环境恶化。当前这一地区生态环境恶化的不断扩大,不但影响了金沙江流域,长江中下游地区的经济建设、生态建设,进而还影响了当地的社会稳定。

A Review of Ecological Environment Changes of Jinshajiang River Basin In the Last Three Decades

Jinsha River is located on the upper reaches of the Changjiang River,which ecological system is varied and complex,such as the meadows,thin tree lawn,wetlands,forests,valley etc.Historically,the modes of production of the ethinic groups can ensure the stability of the ecological system related to the surface,and its ecological environment has been good,which is the key runoff of the Changjiang river basin.Later,with the situation changes of the Tibet and southwest China,the central government had strengthened this area’s rule,which led to the changes of ethnic relations,the changes of means of production,partly ecological environment deterioration.The current ecological environment deterioration continues to expand,which not only influences economic construction and the ecological construction of Jinshajiang river and the Changjiang river,but also influenced the local social stability.
