| 摘 要： | 采用单独流域实验法，利用长期定位观测数据，对森林火灾后河川径流的变化进行了研究。结果表明：大兴安岭特在森林火灾后，河川年轻流量明显增加，５月份融雪径流量有减少趋势。火烧后，森林对水分循环的调控能力减弱，径流的变化更加依赖于降雨。

| Abstract: | Based on the data obtained by single watershed experiment, the changes in streamflow by forest fire were studied. The results showed the forest fire in Daxinganling in 1987 resulted in the increase of annual runoff obviously in the initial stage,the runoff of melting snow in May tended to reduce. After forest fire, the ability to regulate the water circulation of forest was reduced, and the changes in streamflow depended on the precipitation even more. |
