黄土区露天矿排土场生态建设中水分调控技术的研究

平朔露天煤矿位于半干旱的黄土高原区，经过15年的土地复垦与生态重建，已建成比原有生态系统结构更合理，功能更有效的人工生态系统，形成了一套以水分调控技术为核心的比较良好的生态建设技术体系，水分调控技术的提出，形成和发展是针对矿区生态建设的目标而产生的。本文从矿区可持续发展角度，依据露天矿生态建设中水分调控技术的作用和内容，将水分调控技术分为三个阶段；一是水环境安全调控阶段，二是水土保持阶段；三是水分的资源化利用阶段。水资源化利用是今后露天矿生态建设中水分调控技术发展的趋势，为此着重探讨了其技术内容。

STUDY ON WATER ADJUSTING TECHNOLOGY OF ECOLOGICAL CONSTRUCTION IN DUMPINGSITE OF OPENCAST MINE,LOESS AREA

Pingshuo opencast mine area located in semi - arid loess plateau.By land reclamation and ecological rehabilitation for fifteen years, it has become a fine artificial ecosystem whose function is more effective and structure is more reasonable than the original ecosystems. Central to water adjusting technology the researchers have invented a fine ecological construction technology system. The formation and development of this technology is decided on the aim of mine area ecological construction. From the view of sustainable development of mine area, it is divided into three stages of water circumstance safety, soil and water conservation and water utilization based on its function and content. Water utilization is the trend of water adjusting technology in the ecological construction of opencast mine areas afterward so that the author probes into its principles and content in this article.
