| 摘 要： | 在云南热区营造山桂花、西南桦、马尖相思、高阿丁枫等4种人工林,只要经营得当,对林地土壤理化性质并不造成重大影响,不会引起地力迅速衰退。4种人工林土壤变化的大致趋势是:1993~1995年肥力大多略呈下降趋势,1995~1997年有所上升。

| Abstract: | Soil fertility of the plantations of Paramichelia baillonii, Betula alnoides, Acacia Mangium and Altingia excelsa in tropical area of Yunnan does not decline rapidly, and the physical and chemical properties of forestland are not affected greatly if the plantations can be managed properly. The approximate trend of the change of soil in the plantations of four species is that soil fertility declined slightly from 1993 to 1995, and rose a little from 1995 to 1997. |
