Abstract:

Qinghai is a mineral resource province, but imbalanced in its mines distribution and different developing levels in minerals and regions. This paper uses system clustering to analyze its minerals from 18 commodities and regions. Coal, oil, gas, potash, brickused clay and construction sand and others are separated categories in a range of 0.57 clustering distance. In a range of 0.7~1.4, iron, lithium and copper are one category, gold and lead are one, nickel, zinc, chrome and manganese are one among 9 metals. In a range of 0.4184-0.6560, mining developing level in regions can be clustered into 3 categories, Haixi and Haidong, Xining and Haibei, Hainan, Huangnan, Yushu & Guoluo. This paper also gives suggestions for developing minerals in different regions.

摘要：

青海省是一个矿产资源大省，但其矿山的分布却极不均衡，不同矿种和不同地区的矿业发展水平也参差不齐。采用系统聚类方法从矿种和地区两个角度对青海省矿产资源系统进行了聚类分析。通过对18种主要矿产资源的聚类分析，在0.57的聚类距离下形成的主要结论是：煤炭、石油天然气、钾盐、砖瓦用粘土、建筑用砂各为一类，其余为一类。在0.7~1.4的距离下对9种金属矿产资源的聚类结果是：铁、锂、铜各为一类，金和铅为同一类，镍、锌、铬、锰为同一类。通过对8个地区的矿业发展进行聚类分析，形成的结论是：在0.418 4~0.656 0的聚类水平下分为4类，即海西和海东地区各为一类，西宁与海北为同一类，海南、黄南、玉树、果洛为同一类。最后针对不同的矿业类型和地区矿产特点，给出了不同的发展建议。
