| 摘 要： | 2007年5月—2008年6月,研究了旅游干扰下浙江青山湖风景区植物群落的变化.结果表明:随着旅游干扰强度的增加,物种重要值主要集中于黄山松等少数种上,且乔灌木的重要值趋于减少,草本的重要值趋于增加,植物总个体数增加.丰富度指数(D)和多样性指数(H)均为:中度干扰>轻度干扰>重度干扰,均匀度指数(J)为:中度干扰>重度干扰>轻度干扰.在同一层次中,不同干扰间相同物种仅有香樟等,相似性指数(Ss)值均<0.500.轻度干扰对针叶林地的危害较大,D、H和J值都最低,平均值分别为1.188、1.056和0.697;重度干扰对阔叶林地和灌草地的危害较大,灌草地的D值(2.013)最低,阔叶林地的H值(1.286)和J值(0.807)最低;中度干扰则促进了植物多样性增加,有助于生态系统功能的正常发挥.本区植物群落各结构要素的生态安全受到一定的威胁,导致夏蜡梅等土著种减少和狗尾草等外来种侵入.

| Abstract: | From May 2007 to June 2008,an investigation was made on the changes of plant community in Qingshan Lake scenic area of Zhejiang Province under the effects of tourism disturbance.With the increase of tourism disturbance,the importance value of the plants was mainly fastened on a few species such as Pinus hwangshanensis,apt to decrease for tree and shrub species and to increase for herb species,and the individuals of the plants increased.The values of richness index(D) and diversity index(H) were in the order... |
