难忘1998年。那年夏天,发生在长江、黄河、嫩江、松花江、西江、闽江的特大洪水持续百日,29个省份2.3亿人口不同程度受灾,各地估报的直接经济损失高达2484亿元。洪水肆虐后,人们开始反思。一项调查显示,全国有25度以上的坡耕地9100多万亩。 Memorable 1998. That summer, extraordinary floods in the Yangtze River, Yellow River, Nenjiang River, Songhua River, Xijiang River and Minjiang River lasted for a hundred days and the population of 230 million in 29 provinces was affected to varying degrees. The direct economic losses estimated by various places were as high as 248.4 billion yuan. After the floods raged, people began to reflect. A survey shows that there are more than 9100 mu of slope farmland above 25 degrees in the country.
