摘　　要：研究了深圳市宝安区生态风景示范林的不同坡位———上坡和下坡造林地的酶活性与土壤养分关系。结果表明 :土壤养分含量和酶活性呈现下坡 >上坡的倾向。The nutrients and enzyme activities of soil in lower and upper slopes of afforestation Land of ecological scenic forests in Baoan, Shenzhen were studied. The results showed that organic matter, nutrient concentration, and enzyme activity of the soil of lower slope were higher than those in upper slope. Urease and catalase activities were closely correlated with most soil nutrient concentrations.

关 键 词：坡位 造林地 酶活性 土壤养分
