摘要
以宁夏20个地理行政区划的鱼类分布资料为依据,采用欧式距离系数和类平均值法对区域关系进行了聚类分析,并对宁夏鱼类地理区划进行了研究.结果表明,宁夏的鱼类地理区划应分为2个动物地理省,即宁南黄土高原省和宁中北河套荒漠山地省;宁中北河套荒漠山地省又分为3个动物地理州,即宁北半荒漠丘陵地理州、宁夏平原地理州和西部荒漠半荒漠山地地理州.
The fish distribution information in 20 areas of Ningxia Hui Autonomous Region are used in the cluster analysis to settle the zoogeographical relationship of those areas and to make some suggestion for the zoogeographical division. The data are treated with SPSS. The results showed that the zoogeographical regions of fish in Ningxia can be divided into two provinces that South Ningxia Loess Plateau Province, Middle and North Ningxia River-cover Desert Hill Province which is consisted of three prefectures North Ningxia Semi-desert Hill Prefecture, Ningxia Plain Prefecture and West Desert Semi-desert Hill Prefecture.
