高产竹林地土壤过氧化氢酶、脲酶、蛋白酶和蔗糖酶的活性都高于低产竹林地；磷酸酶活性两种地类间无明显不同。低产竹林地各类酶活性与土壤有机质、全氮、水解氮及有效磷含量均有显著或极显著相关性；高产竹林地土壤有效磷含量与所有酶活性都无相关性，磷酸酶活性和土壤有机质、全氮、水解氮及有效磷含量相关性也不显著。
The activities of catalase, urease, protease and sucrase in high-yield bamboo forest were higher than those in low-yield bamboo forest. The phosphatase activity had no significant difference between the two kinds of land. The activity of various enzymes in low yield bamboo forest had significant or extremely significant correlation with the contents of soil organic matter, total nitrogen, hydrolyzed nitrogen and available phosphorus. The content of available phosphorus in high yield bamboo forest had no correlation with the activity of all enzymes, but the activity of phosphatase and soil The correlations of organic matter, total nitrogen, hydrolyzed nitrogen and available phosphorus were not significant.
