| 摘 要： | 对湿地松、枫香混交林及其纯林的土壤理化性质、微生物数量和土壤酶活性等的研究分析，结果表明：与纯林相比，混交林更有利于提高土壤微生物的数量和土壤酶活性；不同的混交方式其效果也各不相同，行间混交提高了土壤微生物的数量，而株间混交更有利于提高土壤酶活性，利于有机质和土壤N、P、K等元素的积累．因此，湿地松和枫香的株间混交林是一种值得推广的造林模式．

| Abstract: | The soil physical and chemical properties,microbial quantity of the soil,soil enzyme activity of mixed forest of Pinus elliottii and Liquidambar formosana and individual forest have all been analyzed in this paper.The result shows that mixed forest is more beneficial to improve microbial quantities and enzyme activity of the soil,compared with mono-species forest.Besides,different mixed mode has different effect.In detail,microbial quantities of the soil of mixed forest between rows have been improved,soil ... |
