淮河中游易涝洼地涝灾特性及成因研究

根据新中国成立以来淮河中游实际发生的洪涝灾害，从分布范围、发生频率、淹没水深、持续时间、洪灾与涝灾的关系等方面分析研究了涝水及涝灾特性，并且从降雨、自然地理、土壤条件、洪涝关系、滞涝区面积、排水体系、管理等方面对淮河中游地区致涝因素进行了深入分析，系统归纳了涝灾成因，旨在为淮河流域易涝洼地治理提供技术支撑。

Study on characteristics and causation of waterlog disaster of waterlogging depressions along mid-reach of Huaihe River

In accordance with the flood-waterlog disasters actually occurred along the mid-reach of Huaihe River since the founding of New China,the characteristics of waterlog disasters therein is analyzed and studied from the aspects of the distribution area,occurrence frequence,inundated water depth,duration,relationship between flood and waterlog,etc.Moreover,the disaster-induced factors of the regions along the mid-reach of Huaihe River are also deeply analyzed on the factors,such as rainfall,physical geography,soil condition,relationship between flood and waterlog,area of detention basin,drainage system,management etc.,and then,the causations of the waterlog are systematically summarized,so as to provide the relevant technical support for harnessing the waterlogging depressions within the Huaihe River Basin.
