摘要：通过对北京市九龙山封育植被的调查 ,并与 1984年的调查结果进行对比分析 ,对本地区主要植被类型 (群丛 )及其变化进行了详细描述 ,并指出该地区植被演替规律和趋势。说明九龙山地区经过多年的封山育林 ,植物群落发生了明显变化。封山育林是一项恢复森林植被 。
Based on the vegetation survey in Beijing Jiulong Mountain, the main vegetation types and their variation are described in detail through the contrast analysis The vegetation succession law and trend are also indicated The vegetation community's variations were found clearly through many years' hillclosing afforestation The bush communities have been formed The timber volume and coverage of the artificial forest were increased clearly The thickness and coverage of the withered leaves and twig dropped to the earth were also increased clearly The succession trend of the vegetation communities both in the sunfaced and shade slopes are clear It is showed that the hillclosing afforestation is an important measure It can restore the forest vegetation, and make them to form the forest ecological network system
