Mine spoil areas are a continuing source of heavy metal contamination for the surrounding environments via the erosion by wind and running water.Revegetation of the mine spoils may be an effective method to reduce the heavy metal spread,because the covering plants can stabilize heavy metals into plant biomass,and also can limit the movement of tailings by wind However,vegetation has been established difficultly in spoil areas due to the scarcity of available nutrients and high levels of toxic heavy metals.Ectomycorrhizal(ECM)fungi can form mutually beneficial symbiotic relationship with host plants,enhancing nutrient and water uptakes and possibly alleviating heavy metal toxicity.

实验选取桂林毛村典型岩溶区林地土壤为研究对象,另选取同地的碎屑岩区林地土壤做比较,表层土壤(＜30cm)每隔10cm采集土样,下层土壤(30-90cm)每隔20cm采集土样.测定土壤总有机碳、水溶性碳、微生物量碳含量.比较岩溶区与碎屑岩区林地土壤不同形态碳的剖面分布,分析碳形态与土壤部分理化性质的关系.结果表明：与碎屑岩林地不同,岩溶区林地土壤总有机碳、水溶性碳、微生物量碳含量在剖面层突肚形分布,
为得到高效耐盐石油烃降解菌,从黄河三角洲石油污染盐渍化土壤中分离出95株细菌,经液体培养初筛、土壤培养复筛以及产表面活性剂性能测定试验,得到2株高效耐盐石油烃降解菌BM38和BF40.通过形态特征、生理生化特征和16S rDNA序列分析,确定BM38为恶臭假单胞菌(Pseudomonas putida),BF40为沙雷氏菌(Serratia sp.).通过液体培养试验,研究了2株菌的耐盐特性和产生
