摘  要：
以黄石市黄荆山采矿废弃地为研究对象,对土壤微生物数量与土壤性状的相关关系进行了探讨。经多元线性逐步回归和直接通径分析发现,含水量和全氮是影响真菌数量的主要因子,其中含水量的影响最大;有机质、p H和速效氮是影响细菌数量的主要因子,其中有机质的影响最大;有机质和含水量是影响放线菌数量的主要因子,其中有机质的影响最大;速效氮、全氮和速效磷是影响固氮菌数量的主要因子,其中速效氮的影响最大。未发现真菌、细菌、放线菌及固氮菌数量与速效钾含量之间有显著的相关性。

摘  要：
The abandoned quarries of Huangjing Mountain in Huangshi city was studied. The correlation between soil microbial quantity and soil physical and chemical properties was discussed. The multiple linear regression and path analysis revealed that, soil water content and total nitrogen were the main influencing factors relating to the fungi amount, and soil water content was the biggest influencing factor. Organic matter, p H and available nitrogen were the main influencing factors to the bacteria amount, and organic matter was the biggest influencing factor. Organic matter and soil water content were the main influencing factors to the actinomycete amount, and organic matter was the biggest influencing factor. Available nitrogen, total nitrogen and available phosphorus were the main influencing factors to the azotobacter amount, and available nitrogen was the biggest influencing factor. The correlation between soil microbial quantity and available potassium was not found.
