根据河南省第一次河湖普查成果统计,河南省达到普查标准(面积>50 km2)的有1030条河流。按照此次普查方案,河流类型分为山地河流、平原水网区河流及混合河流3种类型,其中平原水网区河流的特点是河流集水区域边界无法清晰准确划分,河流很难界定,普查成果中无河流面积数据;混合河流仅安阳河1条河流。河南省以山地河流为主,共985条,占河流总数的95.6%。文章主要讨论河长与流域面积关系,因此仅考虑山地河流。1按面积划分按照流域面积将河流划分为1000 km2及以上、1000 km2以下2个级别,并将1000 km2以下河流细分为500~1000 km2和
According to the results of the first survey of rivers and lakes in Henan Province, 1030 rivers reached the census standard (area> 50 km2) in Henan Province. According to the census program, the types of rivers are divided into three types: rivers in mountainous rivers, rivers in plain water networks and mixed rivers. Among them, the characteristics of rivers in plain water network are that the boundaries of river catchment areas can not be clearly and accurately defined, and the rivers are difficult to define. There is no river area data in the result; only 1 river of Anyang River is mixed. Henan Province, mainly mountain rivers, a total of 985, accounting for 95.6% of the total number of rivers. The article mainly discusses river length and drainage area, so only consider the mountain river. 1 According to the area, divide the river into 1000 km2 and above and 2 below 1000 km2 according to the drainage area, and subdivide the river below 1000 km2 into 500 ~ 1000 km2 and
