近些年，位于中国生态安全“两屏三带”的东部草原煤电基地出现了景观破碎化、草场退化、水土流失等生态环境问题。本文旨在探讨如何利用景观生态学、恢复生态学原理，通过修复、创建或重组等手段调整景观组分与空间格局，实现草原煤电基地生态恢复从土壤重构、植被重建等传统单一生态环境要素修复，向生态系统结构及其生态功能恢复方向拓展，以维持区域生态系统的稳定性。以生态系统之间的结构、功能与过程恢复为核心的景观生态恢复则是煤电基地生态安全格局构建的关键途径。对当前矿区景观生态学的研究不足进行了分析;以我国东部草原煤电基地内的胜利矿区和宝日希勒矿区为例，通过现场调查、多源遥感监测与数值模拟等手段，分析了草原煤电基地由于大规模地形地貌以及土地利用变化导致的主要景观生态问题;提出了草原煤电基地景观生态恢复的关键技术策略，以及在矿区景观生态恢复技术实施过程中的设计与应用案例，为其他类似露天矿区的景观生态恢复提供新的技术方法参考。提出的主要技术策略包括:在宏观尺度上识别与构建草原煤电基地生态源地、生态网络等关键景观组分，结合地貌重塑与生态廊道构建露天矿区景观生态格局的立体优化策略;针对内外排土场景观斑块等重要部位，分别通过大型异构排土场的水土物质流途径识别，构建外排土场水土资源调控系统的策略，以缓解外排土场水土流失与地质稳定性问题;并构建内排土场全生命周期近自然地貌重塑策略，以提升大规模内排土场与周边自然草原景观基质及地表水文系统的融合度。

In recent years,the coal-electricity base of the eastern grassland,which locates at the China’s ecological se- curity zone “two screens and three belts”,has emerged some ecological environment problems such as landscape frag- mentation,grassland degradation,soil erosion and degradation of soils. This paper aims to explore how to use landscape ecology and restoration ecological principles to adjust landscape composition and spatial pattern through restoration, creation or reorganization,so as to realize ecological restoration and maintain the stability of the regional ecosystem of grassland coal-electricity base. Therefore,the ecosystem structure and its ecological function restoration are further em- phasized,rather than the traditional single restoration method,such as soil reconstruction and vegetation reconstruc- tion. The restoration of landscape ecology is the key way to construct the ecological security pattern of coal-electricity base. In this paper,the authors analyzed the current research on landscape ecology in mining area. Taking Shengli min- ing area and Baorixile mining area as examples,the main landscape ecological problems induced by the large-scale landform and land use change were analyzed by the way of field investigation,remote sensing and numerical modeling. Therefore,the authors put forward several key technical strategies for the landscape ecological restoration of grassland coal-electricity base,and some designed and application cases of the landscape ecology restoration for this area,which could be used as guidance for the other open pit mining landscape ecology restoration. The main strategies include:① The whole control of landscape ecological restoration,and the identification and construction strategies of key land- scape components such as ecological source and green infrastructure network and reshaped landscape to three-dimen- sional optimize the landscape ecological pattern;② Based on the analysis of water and soil material flow pathway in large heterogeneous soil dump,the strategy of land and soil resources control system in dump soil field is constructed for soil erosion and geologic stability control;③ The whole life cycle near the natural landform reshaping strategy is proposed by following the morphological characteristics of the surrounding natural mountain slopes to guide the near natural remodeling of the dump site to enhance the fusion degree with the natural landscape and surface water system.
