Abstract

通过对矿区煤矸石风化物上几种不同复垦措施的复垦区 ,进行一系列土壤微生物及其生化特性的分析研究 ,结果 表明: 各类微生物菌群、数量以及生物活性强度、放线菌和真菌的优势种属、土壤养分等均以覆土种植区大于不覆土区 , 豆科区大于禾本科区 ;而覆土厚度 ( 10～ 20cm范围 )对土壤养分、生理群微生物及其活性等影响较小。 可见覆薄层土 ( 10cm左右 )种植豆科植物是矿区复垦中一项快速有效的措施

English Abstract

A serires of soil bacteria and their biochemical characteristics was studied on coal gangue hills by
reclamation measurements. The results show that: all bacteria population and biochemical activity, genus o
actinomyces and fungi, nd soil nutrients on cover ed area with soil were better than those on coal gangue
hills without soil cover. Above indexes on legume areas were better than those of grass family areas with
the same soil cover. But a variety of thick soil layers from 10 to 20 cm did not show significant different in
soil nut rients, physiological bacteria and their activ ities. Planting le ume on thin soil cover ed-coal gangue
hills is a fast and effective measurement for reclamation of coal mining region.
