| Abstract: | 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 |
