摘　　要：信阳市地处豫南山区淮河上游,地形复杂多样,过渡性气候明显,洪涝灾害十分严重,是淮河防洪的重要组成部分。为了正确认识信阳市洪涝灾害的基本特征,把握相关影响因素,提高洪涝灾害防治对策的针对性和实效性,运用历史灾害统计资料进行研究。结果如下:信阳市洪涝灾害具有以下基本特征:数量上,发生次数多,危害严重;时间上,发生具有一定的连续性和周期性,季节分布不均;空间上,发生区域差异显著,重点区域突出。影响因素上,信阳市洪涝灾害的发生发展是区域气候降水、地貌、河流水文、经济社会等因素共同作用的结果,其中气候降水是导致洪涝灾害最为直接的因素,地貌与河流水文是洪涝灾害发生的重要促进因素,经济社会因素对洪涝灾害具有放大与缩小效应。结合实际,信阳市洪涝灾害防治对策应工程措施和非工程措施并重,重点做好如下工作:加强洪涝灾害防治工程建设,注重非工程建设,多措并举综合治理灾害。Xinyang City is located in the southern mountainous area of Henan province, China, the upper reaches of Huaihe River, the terrain complicated and various, the climate transitional obviously, and the flood disaster very seri- ous in the area,is an important part of the flood protection of Huaihe River. In order to understand correctly the basic characteristics of flood disaster in Xinyang City, Grasp the related influencing factors, Improve the pertinence and effectiveness of flood disaster？ Prevention countermeasures, Using the statistical data of historical disaster, the paper analysis the basic characteristics, influencing factors, and countermeasures of the flood disaster of Xinyang Cit- y. The results showed that the flood disaster happened frequently in Xinyang City and disaster situation is vey seri- ous; the flood disaster happened has certain continuity and periodicity, and has uneven seasonal distribution; the flood disaster happened has significant regional differences and the key areas is outstanding. In the aspect of influ- encing factors, the flood disaster happen and develop is the consequence of the interaction of climate and rainfall, to- pography and geomorphology, river hydrology and economic society factors. Combined with the practice, the flood disaster countermeasure of Xinyang City should paying equal attention to the engineering measures and non-engi- neering measures. Focus on the following aspects： To strengthen flood engineering construction; pay more attention to non-engineering construction; and take multi-measures to realize comprehensive control flood disaster.
