摘  要：
为了探讨整地方式对桉树林分生长和林地生态效益的影响,在3种整地方式下的尾巨桉林地分别设置样地和样方进行调查分析,结果表明:机械带垦和炼山全垦的尾巨桉林分生长均较人工穴垦快,炼山全垦的尾巨桉林下植被生物多样性最差,机械带垦的林地土壤有机碳含量最大,炼山全垦林地表层(0~40 cm)土壤含水量最高,人工穴垦林地深层(40~80 cm)土壤含水量最高。

摘  要：
In order to evaluate effects of site preparation methods on the growth and ecological impacts of plantations of Eucalyptus urophylla × E. grandis, tree growth and ecological parameters of plantations established using 3 different site preparation methods were analysed. Results showed that growth of E. urophylla × E. grandis plantations established following burning and full cultivation or mechanical furrowing were superior to those established with manual spot cultivation(i.e. manual digging of planting holes). Biodiversity represented in undergrowth vegetation present in E. urophylla × E. grandis plantations following burning and full cultivation was the lowest of all three site preparation methods. Organic carbon content of plantation soils was highest with site preparation involving furrowing. Water content in the surface layers(0 ~ 40 cm) of soils was highest in plantations established following burning and full cultivation, whilst water content in the deep soil layer(40 ~ 80 cm) was highest in plantations established following manual spot cultivation.
