今年6～8月份,长江流域发生了仅次于1954年的全流域大洪水.本次特大洪水高危水位持续达两个多月,对长江中、下游造成的压力大大超过了1954年.除了长时间大面积暴雨和干支流洪水遭遇等自然因素的影响外,人类对自然无节制的索取,从而遭到大自然的惩罚是更为重要的原因.诸如:气候异常、森林植被遭破坏,分洪区经济开发,湖泊围垦等多项人为活动都是导致今年特大灾害的因素.大灾以后要反思,只有决策科学化、民主化,走经济与社会、环境协调的可持续发展道路才能有美好的未来.
From June to August this year, the Yangtze River basin occurred after the flood of the whole basin in 1954. The high-risk water level of the extra-large flood lasted more than two months, and the pressure on the middle and lower reaches of the Yangtze River greatly exceeded that of 1954. In addition to the long Time heavy rainstorms and the dry tributaries flood and other natural factors, human nature of the uncontrolled access, and thus be punished by nature is more important reason, such as: climate anomalies, the destruction of forest vegetation, flood diversion area Many human activities, such as economic development and lake reclamation, are the causes of the catastrophic catastrophe of this year. After the cataclysm, we must reflect on it. Only through scientific and democratization of the decision-making process can we have a bright future in the path of sustainable development with the coordinated development of economy, society and environment. .
