摘要: 景观生态学在其发展之初的1980年代,提出了关于景观网络研究的基本构想,这些构想需要在景观过程的研究中逐渐被落实和发展。动物移动过程因动物不同于无机物、在斑块或廊道上有着独特丰富的有机体属性特征、并与周围资源环境之间存在复杂反馈而独具特点,则动物移动过程形成的移动网络研究在实现这些基本构想、推动景观生态学发展中贡献独特。因此,总结动物移动网络研究的来源脉络及其对景观生态学的理论贡献对于景观网络领域和景观生态学学科的发展都具有重要的意义。本文抓住景观生态学发展之初提出的关于景观网络概念、网络结构指数和景观连接度的基本构想,寻找和剖析其中所蕴含的景观生态学思想,追踪这些思想如何被落实、发展、并形成目前三个热点方向:动物移动网络模拟、重要值评价和景观连接度分析;总结这些热点内容的研究进展,指出结合动物的空间行为特征是必然发展趋势,最终揭示出动物移动网络研究始终都以发掘斑块或廊道的动物有机体的属性特征(如种群数量)以及描述该属性的差异和联系为方向。正是这种属性的发掘有效地落实、发展和丰富了景观生态学建立之初的构想,对景观生态学的贡献比其他过程更为独特。文章还总结了我国动物移动网络研究与国际相比较为落后的现状,指出其暂时尚未显示出对我国景观生态学的独特贡献;强调发展源于跟踪定位数据的动物行为学研究是减小差距的重要、必要前提。期望本文能引发关于景观网络乃至景观生态学理论发展的方向性思考,为研究者提供参考。

Abstract: In the 1980’s when landscape ecology emerged, scientists conceived the nascent ideas about landscape networks. Those ideas needed to be gradually realized in exploring the concrete landscape processes. Animal movement process is greatly different from other un-organic processes because animals feed complexly back to surrounding environment and provide a variety of biological attributes in each corridor or patch, which was found out to contribute particularly to realize those ideas and improve landscape ecology. Therefore, it is significant to summarize the development of animal movement networks research and its contributions to landscape ecology. Here, we firstly analyzed the earlier ideas of movement networks, network index and landscape connectivity and sought out landscape ecology thoughts embedded in those ideas. Then, we tracked how those ideas were realized, developed, and shaped to 3 current focuses of modeling movement networks, estimating importance of network elements and examining functional landscape connectivity. Summarizing the research progresses of those 3 focuses, we pointed out it is necessary trend to integrate animal behavior. Finally, we illustrated that the movement networks research have been seeking to describe biological attributes on corridor or patch and the spatial heterogeneity of those attributes, which realized and developed those earlier ideas and contributed to landscape ecology more particularly than other un-organic processes. Also, summarizing movement network research progress in China, we pointed out there is a gap behind the developed countries, which have failed to make special contributions to ongoing research in Chinese landscape ecology. We highlighted importance and necessity of behavioral ecology researches deriving from GPS tracking data to improve the animal movement networks research to narrow the gap. This paper aimed to spark guiding concerns for animal movement networks and landscape ecology, providing reference for scientists.
