通过对金沙江干热河谷新银合欢人工林物种多样性方面的研究，讨论了种在退化生态系统功能恢复中的作用及物种多样性与生态系统功能的关系。

The authors investigate and study the species diversity of Leucaena leucocephala plantation , discuss its function of ecology and the relation between species diversity and the function of ecosystem .

垂直结构单调，虽可分为乔木层、灌木层、草本层，但乔灌层均以新银合欢占优势，草本层盖度低。

Although the vertical structure of community can be divided into tree layer , shrub layer and low coverage herb layer , Leucaena leucocephala dominated in tree layer and shrub layer .

新银合欢作为生态恢复初期的先锋树种明显改善了生态系统的微环境，为后继种的入侵和定居创造了条件。

Leucaena leucocephala plantation , as pioneer species in the initial stage of ecosystem restoration , improves micro-environment of ecosystem , and creates favorable conditions for post species to intrude and colonize .

尿素对这些树种苗木的生长也有促进作用，尤其是对川楝、新银合欢、苏门答腊金合欢苗木的增长效果更为显著，生产中用量以0.3%~0.5%为宜；

Carbamide can also promote the growth of these species , especially for Melia toosendan , Leucaena leucocephala cv . Salvador , Acacia glauca , the suggested amount is 0.3 % ~ 0.5 % .

结果表明：新银合欢细根质量在相同范围剖面中并非随树龄的增加而单一增大，而是先减小后增大；

The results indicated that the weights of fine roots of tree were not solely increasing with the increasing tree age , but decreased at first and then increased in the similarly ranged profile .
