矿产资源承载力评价及其环境约束分析——以福建省煤炭资源为例

The Carrying Capacity Evaluation and Environmental Constraints Analysis of Mineral Resources——A Case of Coal Resources in Fujian

以矿产资源经济承载力水平作为评价指标,构建静态和动态相结合的矿产资源承载力评价模型,阐述生态环境承载力对其的约束机制,并以福建省煤炭资源为例采用情景分析法进行实证分析,结果表明:在经济发展的高、中、低三种情景中,静态经济承载剩余年限分别为5.88年、6.21年和6.59年,动态经济承载剩余年限分别为9.81年、11.73年和14.80年,2008年的生态足迹为833.68公顷,2010年开始皆出现生态环境赤字,矿产资源承载力已经成为经济社会可持续发展的制约因素之一。基于实证结果,我们应当采取提高资源利用效率、开发替代资源等提高矿产资源承载力的措施和建议。

Applying the economic carrying capacity of mineral resources as an evaluation index system, the model which was combined with static and dynamic evaluation techniques was built and the constraint mechanism was also analysed for the ecological environmental capacity. The empirical analysis based on scenario analysis for the coal resources of Fujian Province shows that the static economic carrying capacity indicates 5.88 years, 6.21 years, 6.59 ydars and the dynamic economic carrying capacity indicates 9.81 years, 11.73 years, 14.80 years in the high, between and low scenario. The ecological footprint was 833.68 hm2 in 2008. Environmental deficit will generate in 2010. The carrying capacity of mineral resources has become one of the important constraints factors for the economic sustainable development. The paper approaches the feasible advices on increasing the carrying capaci- ty of mineral resources based on empirical analysis results.
