主要对伊春南部１９９６年７月２９日特大洪水灾害进行了全面的调查和研究。调查结果表明：这次洪水是５０～１００ａ一遇的大洪水，洪水发生的主要原因是大面积的集中暴雨所致，但森林起到了明显的削洪减灾作用。森林质量的好坏是影响森林减洪能力的关键因素，并提出了防治洪水的一些相应对策。
Mainly carried out a comprehensive survey and research on the extraordinary flood disaster on July 29, 1996 in southern Yichun. The survey results show that the flood is a major flood of 50-100 years. The main reason for the flood is caused by a large area of heavy rainstorms, but the forest plays a significant role in flood control and disaster mitigation. The quality of forest is the key factor that affects the ability of forest to reduce the flood and puts forward some countermeasures to prevent and treat the flood.
