西藏东部地区矿产资源开发状况及其评价

Status of Exploitation of Mineral Resources in East Tibet and Its Evaluation

2011至2014年西藏东部地区矿产资源开发状况遥感调查工作已经完成了包括13个重点区在内的全区矿产资源开发状况遥感信息提取工作,首次形成了完整覆盖西藏东部地区矿产资源开发全要素数据集,并对其进行综合研究与评价。结果表明,西藏东部地区存在包括矿山开发利用状况需进一步改善、矿产资源规划执行率有待提高以及存在违法矿山开采现象等问题。矿产资源开发强度大和较大的地区集中分布在墨竹工卡、林周和江达等7个县级单元。上述结果可为下一阶段西藏自治区矿产资源规划制定、矿产资源开发状况遥感调查重点区的部署及其动态巡查工作提供决策依据。

The survey of East Tibet via remote-sensing started in 2011 and completed in 2014 for status of the exploitation of mineral resources in the region, covering 13 key areas. For the first time, a complete all-factor dataset concerning min-eral resource exploitation all over East Tibet has been established based on the domestic satellite data for comprehensive study and evaluation. Results show that the exploitation needs to be improved, it is still quite low in mineral resources ex-ploitation program execution rate and ridden with illegal mining. A total of seven counties, including Mozhugongka, Linz-hou, Jiangda and some others were sorted into the category of high intensity in exploitation and high density in distribution of minings. All the findings in this study might serve as valuable references for making mineral resources exploitation pro-grams in East Tibet and as scientific basis for decision-making in deploying focal areas for remote-sensing survey of mineral resources exploitation and its dynamics in the next five years.
