摘　　要：针对洪水具有资源和灾害双重属性且洪水资源利用过程中的风险研究必不可少,在分析平原地区泡沼蓄洪利用过程的基础上,对泡沼蓄洪的主要风险因子进行了识别,建立了二维泡沼蓄洪风险估算模型,并以白城市茨勒泡在7、8月间的蓄洪为例,计算了不同蓄洪量所对应的风险率。结果表明,茨勒泡在7、8月间蓄洪风险的等级基本上为轻险。为制定泡沼在适宜时机引蓄适当洪量提供了理论依据。Due to the characteristics of flood benefit and disaster,it is necessary to study on the risk of flood resources utilization.Based on the process of flood storage with ponds,the main risk factors of flood storage in ponds have been identified and two-dimensional risk estimation model had been built.Taking the Cile Pond in Baicheng City in July and August for an example,the risk ratio corresponding to the different flood volume has been calculated.The results show that the level of risk for flood storage in July and August is light.Thus,it provides theory basis for flood storage in pond at the right time.
