研究了深圳市宝安区生态风景示范林的 3种典型造林地———灌丛地、马尾松残林地和水土流失地的土壤养分状况、微生物数量和酶活性 .结果表明 :各造林地养分含量偏低 ,细菌占微生物数量的 86 %以上 .土壤养分含量、微生物数量和酶活性呈现灌丛地 >马尾松残林地 >水土流失地的倾向
The soil nutrient status, the number of microbes and the enzyme activity of three representative afforestation sites in Shrubland, Pinus massoniana forest and soil erosion were studied in Baoan District of Shenzhen City.The results showed that the nutrient contents Low, bacteria accounted for more than 86% of the number of microorganisms.The soil nutrient content, microbial quantity and enzyme activity showed shrubs> Masson pine forest> tendency of soil and water loss
