基于植被区划和生态敏感性的中国煤矿生态恢复策略

Ecological restoration strategies for coal mines in China based on vegetation zones and ecological sensitivity

  • 摘要: 煤炭是我国的主要能源,也是我国长期以来发展的最重要驱动力,并且在未来很长一段时间内将继续作为我国社会与经济发展的主要能源。但我国长期的煤炭开采活动已经对生态环境造成严重破坏,亟待进行全面生态恢复。目前,我国煤矿生态恢复大多局限于一处或几处矿区这类小尺度范围,缺乏国土空间层面的生态修复规划,相应的生态恢复策略也仍待明确。煤矿生态恢复是一项全国性系统生态工程,应以“借自然之力恢复自然”为理念,以当地生态敏感性问题为依据,以停止破坏自然生态系统并且继续提供生态系统服务为宗旨,以改善矿区人居环境质量为出发点。全国煤矿生态恢复策略的制定基于以下4个方面:第一,以我国植被区划为基础,因地制宜地选择潜在植被类型;第二,计算归一化综合生态敏感性(NIES)用以表征煤矿生态恢复紧迫性,再借助空间自相关性分析判断不同NIES煤矿的聚集关系与模式;第三,对煤矿和当地人口分布情况进行缓冲区分析,得到煤矿生态恢复的获益人口;第四,将煤矿的NIES和煤矿恢复获益人数进行聚类分析,判断煤矿生态恢复的优先区域。综合上述结果,根据我国煤矿的空间分布情况分区域制定相应的生态恢复策略。

     

    Abstract: Coal is the main source of energy in China and the most important driver of our development for a long time. It is predicted that coal is going to be the main energy source for our social and economic development in the future. However, the long-term coal mining activities in China have caused serious damage to the ecological environment and comprehensive ecological restoration is urgently needed. At present, most coal mine ecological restoration is limited within a small scale in China, such as one or several mine areas, lacking of ecological restoration planning at the national spatial level, and corresponding ecological restoration strategies. The ecological restoration of coal mines is a national systematic ecological project that should be carried out with the concept of “restoring nature by the power of nature”, on the basis of local ecological sensitivity issues, with the purpose of stopping the destruction of natural ecosystems and continuing to provide ecosystem services, and with the starting point of improving the quality of the human environment in mining areas. The development of strategies for coal mine ecological restoration is based on the following four aspects: First, potential vegetation types are selected based on China’s vegetation zoning and according to local ambient conditions; Second, Normalized Integrated Ecological Sensitivity is calculated to characterize the urgency of ecological restoration coal mine and then spatial auto-correlation analysis is used to determine the aggregation relationship and pattern of coal mines with different NIES. Third, a buffer zone analysis is conducted on coal mines and population to obtain the population benefiting from the ecological restoration. Based on the above results, the corresponding ecological restoration strategies were developed according to the areas of coal mines in China.
