| 摘 要： | 根据岛屿生物地理学理论及其物种-面积关系:S=cAz,构建数学生态模型,研究集约经营对毛竹林物种多样性的影响.得出两点:(1)竹林生物多样性对集约经营的响应具有一定的面积效应,即原粗放经营竹林的面积越大,物种减少幅度就越大,原竹林越小,物种减少幅度就越小;(2)毛竹林诱导扩张过程符合Logistic方程,随着时间的延长... |

| Abstract: | From a landscape perspective and based on the theory of island biogeography and its species-area relationship:S=cAz,mathematic ecological models were established to analyze the changes of species diversity in Phyllostachys edulis forests or woody forests responses to the habitat destruction due to intensive management.Here the activity range of species apart from the borders of forests is also considered as a part of the area in the species-area formula.The followings were found:(1) intensive management had... |
