%X Studies on the soil microbes, soil enzyme activity and soil biochemical intensity in copper mining wasteland indicated that the total quantity of major soil microbes declined by 68.43%-80.32%, compared with that of the non-minig soil. The proportion of bacteria and actinomyces decreased, while that of fungi did not changed obviously. The amount of major physiological groups including ammonifiers, nitrogen fixing bacteria, cellulose decomposing bacteria, aerobic nitrogen fixing bacteria and anaerobic nitrogen fixing bacteria all decreased, and soil basic respiration descended, compared with the control. The activity of soil enzymes weakened, which included urease, sucrase, proteinase, acid phosphtase, peroxidase, polyphenol oxidase and dehydrogenase. Soil biochemical intensity including ammonification, nitrification, nitrogen fixation and cellulose decomposition descended, and the circulation of C and N in mining soil inhibited. All the results showed that the weakening of microbial activity was one of major characteristics in reclaimed mining soil.
