毛竹林物种多样性对集约经营的响应模型
Simulation of Species Diversity in Phyllostachys edulis Forest Responses to the Habitat Destruction due to Intensive Management
摘要
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 an influence on species diversity in the Ph. edulis forest ( i. e. the larger the area of forest was, the larger the species loss was;the smaller the area of forest was, the smaller the species loss was during intensive management); (2) the expansion to woody forest of the Ph. edulis forest fulfilled the Logistic equation, and the loss of species diversity could reach its limit as time went on.关键词
