摘要
景观连接度作为景观生态学的主要研究内容,是对景观结构促进或阻碍生态过程的景观度量。景观连接度为森林景观结构与病虫害种群空间分布、栖息生境景观结构格局、扩散能力及途径等生态学过程的研究提供了新方法。基于昆虫和病原微生物对景观结构响应的生态学过程制定森林病虫害的控制方法,符合森林有害生物生态控制基本要求和原则,为安全、有效、持续地控制森林病虫害提供理论基础。简单介绍了景观连接度的概念、特征、研究内容和生态学意义,就国内外景观连接度应用于森林昆虫与病原微生物方面的研究进行了综述,进而展望了景观连接度在森林病虫害控制中的研究方向和应用前景。
As the main research content in landscape ecology, the landscape connectivity is the degree of landscape structure to facilitate or impede ecological process. Landscape connectivity provides new methods and measures for lots of ecological processes, including forest landscape structure, spalial contribution of diseases and insect pests＇ population, landscape structure pattern of habitat, ecology dispersal ability and routes, and so on. Methods of controlling forest disease and pests are based on ecological process of diseases and insect pest response to landscape structure. These accord with essential requirements and principles of forest pests ecological controlling and provide theoretical basis for securely, efficiently and persistently controlling forest diseases and insect pests. In this review we introduce the concept, characteristic, research context and ecological significance of landscape connectivity, focus on the research progress of landscape connectivity in forest diseases and insect pests, and then preview the research orientation and potential application of landscape connectivity in control forest pests.
