摘要: 基于藏中地区的矿产资源分布情况和地质背景,划分了8个评价区,以铜矿为研究对象,构建5个一级指标,12个二级指标,运用熵值法客观确定指标的权重,并根据指标权重和指标数据值相乘求出最后的综合得分值,根据各评价区分值对藏中地区的铜矿资源保障程度进行分析,评价结果为:冈底斯-念青唐古拉中成矿带上铜矿保障程度分析结果最好,成矿带南北两侧铜矿化相对较弱;藏中地区铜矿保障程度呈2个中心型分布,分别以谢通门县和拉萨市为中心向周边扩散。其结果可推广应用到其他区域矿产资源的保障程度研究中。

Abstract: Based on the distribution of mineral resources and geological background in central Tibet area,eight evaluation areas are divided.With copper mine as the research object,five A-level indicators,and 12 B-level indicators are constructed.The entropy method is adopted to determine the index weight objectively,and the final complex value was obtained by multiplying the index weight and the index data.According to the assessment scores of each district,the security level of copper resources in the central region of Tibet is analyzed.The conclusions are as follows: copper minerals at Gangdisi-Nianqing Tanggula copper ore belt has a better security level,and copper mineralization at north and south sides of the copper belt is relatively weak; copper minerals in central region of Tibet are distributed into two centers,that is,Xietongmon County and Lhasa City as the center spreading to the surrounding area respectively.The research results can be promoted and applied into the security level study of mineral resources in other areas.
