摘要
微生物复垦是矿区生态重建的有效途径。遥感技术特别是高光谱遥感技术可以快速准确地获取微生物复垦后植被的生长状态和土壤性状改良的实时信息,为评估微生物复垦技术对矿区土地恢复和生态重建的作用提供了技术支撑。概述了遥感技术在矿区植被恢复、矿渣石排土场复垦、采矿沉陷地复垦和复垦区重金属污染监测等方面的应用和研究现状,以及微生物技术在改良煤矸石环境、治理采矿沉陷地和修复重金属污染场地中的作用和研究现状,分析了遥感技术应用于监测微生物复垦效果的理论依据,并讨论了今后遥感技术在微生物复垦中的应用潜力,以期为未来快速、准确、无损地监测微生物复垦植被的生长状况提供新方法,并为评价微生物技术在矿区生态重建中的作用提供参考。
Microbial reclamation is an effective means for ecological restoration in coal mining. Remote sensing, especially hyperspectral remote sensing, can rapidly and precisely determine the growth status of plants in the field and the improvement of soil properties, thus providing important technical support for implementation of microbial technology to land restoration and ecological environment rehabilitation in coal mining. This paper summarized in detail the application of remote sensing to monitoring the plants recovery, reclamation of waste dump of tail slag and subsidence and pollution of heavy metals in reclaimed areas, and the application of microbial technology to improving the environment of coal wastes, managing mining subsidence land and restoring land polluted by heavy metals. Some ideas of remote sensing technology applied in microbial reclamation for future research were discussed in this paper, which could provide an important reference and guideline for quick, accurate and undamaged monitoring of growth of plants reclaimed with microorganism and estimation of microbial technology implemented in ecological restoration in coal mining in the future.
