陕北采煤迹地LUCC过程及区域内生态系统主控因子识别研究探讨

Study on the LUCC Process and the Identification of the Main Controlling Factors of the Ecological System in the Coal Mining Area in Northern Shaanxi

摘要: 采煤迹地是一种因人类及自然因子的严重干扰，生态环境发生巨大改变，生态系统的组成与结构发生了急剧变化的退化生态系统。由于人们迄今尚不清楚煤炭资源开采对矿区生态环境效应的影响机理，避免矿区生态环境破坏、修复受损土地、改善矿区生态环境等都是十分复杂、困难和富有挑战的工作。因此，了解煤炭资源开采所引起的LUCC变化及其响应规律是协调采煤迹地土地复垦与生态环境保护迫切需要解决的关键科学问题之一。科学量化陕北采煤迹地LUCC过程，开展区域内生态系统主控因子识别的研究，对于其他同类环境中LUCC过程和生态环境保护具有启示作用和示范意义。

Abstract: The coal mining site is a degraded ecosystem that has undergone tremendous changes in the ecological environment and the composition and structure of the ecosystem due to severe interference from humans and natural factors. Since people have not yet understood the mechanism of impact of coal resource mining on the ecological environment of the mining area, avoiding damage to the ecological environment of the mining area, repairing damaged land, and improving the ecological environment of the mining area are all very complex, difficult and challenging tasks. Therefore, understanding the changes of LUCC caused by coal resource mining and its response rules is one of the key scientific issues that urgently need to be resolved in coordinating the land reclamation of coal mining sites and ecological environment protection. Scientifically quantify the LUCC process in coal mining sites in northern Shaanxi, and carry out research on the identification of the main control factors of the ecosystem in the region, which has enlightening and demonstrative significance for the LUCC process and ecological environment protection in other similar environments.
