摘要
边缘效应是景观生态学的重要概念,它在研究群落景观的能量流、物质流和有机体流等生态过程中起着重要的作用。边缘格局特征的相互作用显著,是景观生态学理论探讨的热点之一。对边缘效应的概念与内涵、研究的相关领域、影响因素、定量评价方法及其意义方面进行了一些阐述。随着森林破碎化程度的加深,边缘效应影响范围和深度也随之增加;同时随着科学技术的发展和研究方法的改进,将不断促进边缘效应生物机制的研究和发展。对边缘效应的深入研究有助于森林经营管理。
The edge effect is the landscape ecology important concept. It falls the landscape on the research group energy flows, the matter flows with the organism flows and so on in the ecology process, is playing the vital role. Is remarkable with the boundary pattern characteristic mutual function, is one of landscape ecology theory discussion hot spots. This article to the edge effect concept and the connotation, there search related domain, the influence factor, the quantitative evaluation method and it＇s the significance aspect has carded on some elaborations. Along with forest broken degree deepening, edge effect influence scope and depth also along with it increase. Meanwhile along with the science and technology development and the research technique improvement, unceasingly will promote the edge effect biology mechanism research and the development. It will be helpful to the edge effect thorough research to current and the next forest management.
