| 摘 要： | 在中国南部开展对荒山马尾松(Pinus massoniana)林养分循环受人类活动影响的调查.位于江西省兴国县研究地点的一些农民从森林生态系统中收取有机物作为燃料,这引起养分循环的断裂和植被恢复的延误以及土壤侵蚀的发生.收取的量估算为相当于5.92t/hm2有机物和21.4kg/hm2氮.如果收取停止,10年之后,有机物在森林地表枯枝落叶层的积累将可恢复. |

| Abstract: | This article examines the influences of human impact on the nutrient cycling in a deteriorated Pinus massoniana forest in southern China.The people of Xinggou District in Jianxi Province removed the organic matter from forest ecosystems for use as fuel.This causes the break of the nutrient cycling,the delaying of vegetation recovery,and soil erosion.The amounts of removal were estimated 5.92 t/hm2/yr in organic matter and 21.4 kg/hm2/yr in nitrogen.If the removal was stopped,the accumulation of organic matter in the forest floor would recover after ten years. |
