露天煤矿区低碳土地利用途径研究

    Research on the low-carbon land use in opencast coal mine area

    • 摘要: 在我国生态文明建设战略背景下,遵循“山水林田湖草”这一生命共同体理念,探寻适合矿区的低碳土地利用方式显得尤为重要。露天矿开采产生了大量扰动剧烈的损毁土地,破坏地表原有植被造成碳储量部分丧失或全部丧失。本文结合国内外有关低碳土地利用的研究背景与实践,从矿区低碳土地利用的原则、目标、途径三方面,寻求矿区“减排增汇”的方法,并在现有“5R”原则上依据矿区特殊性进行优化。通过地貌重塑、土壤重构、植被重建等土地复垦工程的实施,将矿区生态系统内“碳源”型用地逐渐向“碳汇”型用地转变。从土地利用空间布局、方式进行重新规划与重组,使结构合理、功能高效、时空安排有序。在煤炭开采、土地复垦工程实施过程中,通过采取相关措施减少能源消耗、降低碳排放强度、提高土地复垦率、提升矿区碳汇功能。

       

      Abstract: In the context of China’s ecological civilization construction strategy, based on the concept of “ecological safety of mountains, rivers, forests, farmlands, lakes, and grassland”, it is particularly important to explore low-carbon land use patterns which are suitable for mining areas.The open pit mining process destroyed the original vegetation on the surface and caused partial or total loss of carbon storage.This paper makes use of research and practice on low-carbon land use at home and abroad.We seek ways to reduce emissions and increase carbon sequestration from the three aspects of the principles, objectives and approaches of low-carbon land use in mining areas.According to the existing “5R” principle, the method is optimized according to the specificity of the mining area.Through the implementation of land reclamation projects such as landform reconstruction, soil reconstruction, and vegetation recovery, the “carbon source” type land in the mining ecosystem will be gradually transformed into “carbon sequestration” land.Through the re-planning of the spatial layout and methods of land use, the ultimate goal is to make the land use structure more reasonable, more efficient, and more scientific in time and space.In the process of coal mining and land reclamation project, through measures to reduce energy consumption and reduce carbon intensity, as a result, the land reclamation rate will increase and the carbon sequestration function of the mining area will also be improved.
