| 摘 要： | 利用黑龙江省实际水文气象监测资料分析表明,山洪发生时空分布特征基本同全省暴雨分布相一致;山洪暴发前3h、24h、及前10天降雨量为有效关键时段,寒冷的气候条件,森林过度采伐对山洪暴发影响关系很大;特别是20世纪80年代以来黑龙江省气候明显变暖,暴雨次数也明显增多;根据山体滑坡、泥石流、土壤侵蚀的原理结合黑龙江省山洪发生特点,提出了山洪发生的概念模型及权重指标和山洪发生的等级。

| Abstract: | The analysis on the basis of the hydro-meteorological observation data in Heilongjiang Province shows that the spatial-temporal distribution characteristics of mountain torrents are in agreement with those of heavy rainfall.The rain amounts of 3 hours,24 hours and 10 days before a mountain torrent are most crucial for the occurrence of mountain torrents.The climate conditions and excessive deforestation are closely related to the occurrence of mountain torrents.Since the 1980s,the climate in Heilongjiang has become warm,and the number of heavy rains has increased obviously.Based on the mechanisms of landslides,debris flows,and soil erosion,in combination with the characteristics of mountain torrents in Heilongjiang Province,the conceptual models,weight index,and grades for mountain torrents are presented. |
