摘 要:生态交错带是相邻生态系统之间的过渡带,是生态系统结构和功能在时、空尺度上变化较快的区域,也是生物多样性丰富区、全球变化敏感区。生态交错带位置和宽度的判定是定量研究交错带生态过程的基础,对生物多样性保护、片断化森林生态系统的管理与恢复以及自然保护区的功能分区都具有重要意义。由于生态交错带本身的复杂性,在相当程度上依赖于尺度水平,并受到各种自然和人为因素的影响,以致于目前还缺乏公认的原理和方法定量研究生态交错带,对其位置、宽度判定和动态变化研究一直处于不断的探索中。在分析大量相关研究资料的基础上,文章对生态交错带宽度判定方法以及影响因子进行论述,并对生态交错带宽度判定的研究前景进行展望。Ecotone is a transition zone of adjacent ecosystems, where ecological structure and function change rapidly over time and across space, and rich biodiversity is presented. Moreover, the ecotone is sensitive to global climate change. Ecotone location and width quantification is important for studying the ecological process. It is also very importance for biodiversity conservation, forest ecosystem management, the fragmented habitat restoration, and nature reserves management zone design. Due to the complexity and scale dependence of ecotone, and also affected by both natural and human disturbance factors, there are no accepted principles and methods for quantifying the ecotone's location, width, and change. New methods need to be developed in future studies. Base on a large number of literatures review, in this paper we presents the drawbacks and merits of the current methods for ecotone width quantification, and analyzes the influencing factors. Finally, we offer some syntheses and perspectives regarding for the ecotone width quantification research in the future.
