中文摘要：

选择传统的水体周长、水体总面积和河流密度以及最新的水体空间分布多样性4类地表水体分布特征评价参数，对河南省中部典型样区的地表水体信息进行深入分析。研究表明，当研究区内水体以河流等线状水体类型为主时，4者均能较好地描述区域地表水体的分布特征，且两两之间具有明显的一元线性正相关关系，判定系数平均达到0．89左右；当研究区由河流、湖泊、水库等复杂水体类型构成时，选择最新的水体空间分布多样性评价参数能够更好地描述区域地表水体的空间分布特征。

英文摘要：

There is a significant spatial imbalance in the water resources distribution in China and the study on it is very important for the sustainable use of natural resources and rational distribution of agricultural structure. A typical research area in central Henan Province is selected for a correlative analysis about surface water distribution characteristic between the traditional indices （water perimeter, water area and drainage density） and the new water spatial distribution diversity methodology. Results show that there is a significant positive relationship among these four indices with the average coefficient of determination （R2） of 0.89 when the regional water is predominated by rivers or such linear surface water types, and in this situation each of these indices is suitable. However, when the regional water is predominated by rivers, lakes, reservoirs and such complex surface water types, the newest index ＇ water spatial distribution diversity＇ performs better and should be chosen in describing the water spatial distribution characteristic.
