土壤调查

In order to investigate the succession of soil microbial community with ecosystem development, soil samples of three successional stages (i.e., barren stage, cryptogamic crust stage and herbaceous vascular plant community stage) from two tailings wastelands (Yangshanchong tailings wasteland discarded in 2001 and New Tongguanshan tailings wasteland discarded in 1991) were collected and soil microbial biomass was determined by methods of typical plate culture' and molecular biology.

该研究以2处（即，铜陵杨山冲尾矿废弃地和铜官山新尾矿废弃地）不同时期弃置的、处于3个演替阶段（原生裸地阶段、隐花植物结皮阶段和草本维管植物群落阶段）的铜尾矿废弃地为研究对象，利用传统培养法和分子生物学法相结合的手段对土壤微生物量和土壤微生物群落结构变化及其影响因素进行了调查。

In this paper, data of 3061 surface (0~20 cm) soil samples containing 52 elements total contents and pH values obtained from Chengdu Economic Zone, Sichuan Province, are analyzed by cluster analysis, the numbers of which are equal to the group ones of soil genesic classification.
