| 摘 要： | 海南岛东部海岸钛锆砂矿废弃地采用木麻黄进行植被恢复,通过对有残余西瓜藤蔓和稀土肥料处理的木麻黄林地(处理林地)与没有任何处理的木麻黄林地(对照林地)进行比较研究.结果显示:1)处理林地林木的树高、基径、胸径均显著大于对照林地;2)处理林地植物-土壤系统中各分室的养分元素N、P、K含量均大于对照林地对应值;3)两个林地中养分元素的分布格局均为:叶>粗枝>根>土;4)两个林地植物-土壤系统各分室的养分元素有着相似的季节变化.处理林地的植被恢复优于对照林地.

| Abstract: | The vegetation was restored by using Casuarina equisetifolia on the mining site in the eastern coast of Hainan Island. In this paper, a comparative study was conducted of the treated forest with withered watermelon vines and rare earth fertilizer and the blank forest without any treatment. The results showed that: 1) the growth index of treated forest were all significantly greater than those of the blank forest; 2) the concentrations of nutrient elements N, P and K in different compartments were all higher than those in the blank forest; 3) the distribution patterns of nutrients in both forests were as: needle> branch> root> soil; 4) there were similar dynamics patterns of nutrients in the two forests. The vegetation restoration status in the treated forest was better than that in blank forest. |
