神东矿区采煤沉陷地微生物复垦动态监测与生态效应

 利用环境减灾小卫星(HJ-CCD)产品,通过归一化植被指数(NDVI)、植被覆盖度(F_g)和叶面积指数(LAI)数据动态监测神东矿区采煤沉陷地微生物复垦的效果,与同期现场统计数据(株高、地径和冠幅)的对比分析表明,接菌提高了植被覆盖度和地上植物生物量,有效恢复了地表植被.对接种丛枝菌根真菌紫穗槐(Amorpha fruticosa L.)根际土壤采样进行试验分析,结果表明接菌改良了植物根际微环境,扩大了根系吸收营养的范围,有利于矿区植被的恢复和重建.

Dynamic Monitoring and Ecological Effect of Microbial Reclamation on Subsided Land in Area of Shendong Coal Mine Area

By taking the result of remote sensing on subsided land in the area of Shendong coal mine as an example, the Normalized Difference Vegetation Index (NDVI), vegetation fraction (F_g), and Leaf Area Index (LAI) data from environment and disaster reduction small satellites (HJ-CCD) images were applied to dynamically monitor mining subsidence land reclamation effects of microbial ecological in the area of Shendong mining. The remote sensing data were compared with the sampling experimental data in the same period; they were plant height, ground diameter, and crown width. It is discovered that the microbial reclamation improves vegetation fraction and ground biomass, and recovers the vegetation effectively. The microbe of microbial reclamation in the area of Shendong mining is Arbuscular Mycorrhizal Fungi (AMF) which inoculated in Amorpha fruticosa L. Through rhizosphere sampling experimental analysis, the results show that AMF inoculation could improve the plant micro environment, enlarge the root of the nutrient range, and is able to help on the vegetation restoration and reconstruction of mining area.
