1998年长江大水之后,中央提出了“32字”方针,通过山地丘陵的植被恢复,中下游的退田还湖,长江干流河道整治,加上三峡水库的建成,应该说长江流域的抗洪能力已经得到前所未有的增强。但不可否认的是,目前从防洪观念到战略都需要进行调整以适应长江流域自然人文环境的新变化。 After the flood in the Yangtze River in 1998, the Central Government proposed the “32 characters” principle. Through the restoration of vegetation in the mountain hills, the return of farmland to the lake in the middle and lower reaches of the Yangtze River, the improvement of the mainstream of the Yangtze River and the completion of the Three Gorges Reservoir, Has been enhanced as never before. However, it is undeniable that the current concept of flood control needs to be adjusted to adapt to the new changes in the natural and human environment in the Yangtze River Basin.
