长江特大洪灾的生态环境问题

长江特大洪灾是生态破坏危及环境安全的典型例子，直接与流域内森林锐减，水土流失，围湖造田，经济开发过速，倾倒垃圾堵塞江湖和温室效应使海平面上升有关。根本的防治对策，在于改变观念，坚持可持续发展，加大环保执法力度，保护生态环境。

Ecological problems Brought About by Deluge of the yantze River

The deluge of the Yangtze River is a particular example of endangering the environmental security by ecological damage. It has close relation with the sharp decrease of forest, water and soil erosion, reclaiming fields from lake,over-quickened economic development, river and lake blocking by dumping wastes and the rising of sea level due to the greenhouse effect. The fundamental countermeasure is to change views, insist on sustainable development, enhance environmental legal enforcement and protect the ecological environment.
