中文摘要:矿区土地复垦是改善矿区受损生态环境和恢复破坏土地利用的重要技术途径,但它对土壤碳库和植被碳库的作用及其大小目前研究还不充分。本文以淮北矿区为例,在综合现有农地、林地、湿地、草地、建设用地等碳源碳汇模型的基础上,建立了矿区土地复垦碳减排效果测度模型并评估了淮北矿区土地复垦碳减排效果。结果表明:耕地(复垦前)—耕地(复垦后)的复垦模式的碳汇能力有所提高,废弃地—耕地、林地的碳减排效果最显著,积水区向其它用地类型转化的碳减排效应并不明显甚至会变成碳源,煤矸石充填复垦可有效减少CO2的潜在排放。测算结果表明,淮北矿区已复垦的1.05x104hm2损毁土地,年CO2吸收量可增加1.68 x108kg,碳减排效益明显。由此证明,矿区土地复垦是矿山碳减排的一条重要途径。

Evaluation Model and Empirical Study of Carbon Emission Reduction Effect from Mining Land Reclamation
Abstract:Mining land reclamation is an important way to improve the ecological environment of mining area and restore the service of damaged land, but little studies focused quantitatively on its effect to soil carbon pool, plant carbon pool. This paper developed an effect model of carbon emission reduction of land reclamation synthesizing the existing models of carbon resource , carbon sink of agricultural land, forest land, wet land and construction land, and evaluated the carbon emission reduction effect of land reclamation in Huaibei mining area. The results show that the carbon reduction effect of cultivated land(before damaged) to cultivated land(after reclamation) reclaimed improves, but waste land reclaimed to cultivated land or forest land is most effective, and carbon emission effect of original wet land which transformed to other type of land use turns out inconspicuous or even becomes a carbon resource , and coal gauge used as filling material can effectively reduce potential emission of CO2. Results of calculation show that Huaibei mining land reclamation succeeded on 1.05x104 hm2 damaged land and annually absorbed dose of CO2 increased by 1.68 x108 kg, so carbon sink effect was obvious. Therefore, mining land reclamation is an important way of carbon emission reducing.
