| 摘 要： | 以兴隆县试验区为代表，研究分析首都周围绿化工程改良土壤养分状况及改善林木生长条件的效果。试验结果表明：油松纯林可提高土壤养分含量，但是土壤ｐＨ值下降；山杨、刺槐等阔叶林使土壤养分和ｐＨ值都得到改良，刺槐林效果尤为明显。

| Abstract: | Taking the experimental areas in Xinglong county as examples, the soil nutrients and tree growth in different plantations were studied to estimate the effect of green engineering around Beijing.The experiment results showed that the concentration of soil nutrients increased, but pH decreased in Pinus tabulaeformis plantations. The concentration of soil nutrients and pH both increased in the broad leaved plantations of Pupulus davidiana and Robinia pseudoacacia. The effect of R.pseudocacia was very significant. |
