【摘要】 以宁夏20个县市区域和贺兰山、六盘山的蝗虫分布资料为依据,用Jaccard距离系数和类平均值法对区域关系进行聚类分析,并对地理区划进行了研究.结果表明,宁夏蝗虫的地理区划应分为3个省,即六盘山山地省、银川平原省和贺兰山荒漠黄土高原省.六盘山山地省是六盘山地区,银川平原省包括从北部平罗开始到南部中卫的银川平原地区,贺兰山荒漠黄土高原省分为三个州:贺兰山山地州、荒漠半荒漠州(盐池和同心)和黄土高原州(包括海原、固原、泾源、西吉、隆德、彭阳).更多还原

【Abstract】 The Grasshopper distribution information in 22 Areas of Ningxia Huizu Autonomous Region are used in the cluster analysis to settle the zoogeographical relationship of those Areas and to make some suggestions for the zoogeographical division. The data is treated with the DPS (Data Processing System). The results showing: The zoogeographical regions in Ningxia can be divide into three province that Liupanshan Mountains province, Yinchuan Plain province, Helanshan Mountains, desert, Loss Plateau province. Helanshan Mountains, desert, Loss Plateau province is consisted of three prefectures: Helanshan Mountains prefecture, Desert prefecture (Tongxin county and Yanchi county) and Loss Plateau prefecture (including Haiyuan, Guyuan, Jingyuan, Xiji, Longde and Pengyang counties).更多还原
