Landscape sustainability and land sustainability are interrelated and complementary research fields, rooted respectively in ecological and geographic sciences, but both embracing sustainability as their ultimate goal. However, it is not clear how these two fields have developed in recent decades, and whether they have interacted synergistically to advance the science and practice of sustainability. Thus, here we have conducted a bibliometric comparison of these two fields using multiple quantitative methods, including trend analysis, theme mining, citation network analysis, and collaboration network analysis, further augmented by qualitative synthesis. We have found: (1) both research fields have entered a period of rapid development around 2010, following their incubation and emerging phases; (2) landscape sustainability research has focused primarily on the biodiversity-ecosystem function-ecosystem services-human wellbeing nexus in changing landscapes, whereas land sustainability research has concentrated primarily on the causes, dynamics, and impacts of land use and land cover change, as well as sustainable land use and management; (3) Cross-referencing between the two fields is rare, reflecting weak interactions between the two scientific communities. Thus, although some interdisciplinary teams and individual researchers have begun to work together across the two fields, landscape sustainability and land sustainability, as two research fields, remain largely independent of each other. To enhance their synergistic interactions, we recommend that scientists and practitioners from both fields promote joint professional organizations and conferences, and foster broad-scale collaborative projects together to improve the sustainability of landscapes and regions in theory and practice.

景观可持续性和土地可持续性：文献计量分析


景观可持续性和土地可持续性是相互关联和互补的研究领域，分别植根于生态科学和地理科学，但都将可持续性作为其最终目标。然而，目前尚不清楚这两个领域在近几十年来是如何发展的，以及它们是否协同作用以推进可持续发展的科学和实践。因此，我们在这里使用多种定量方法对这两个领域进行了文献计量学比较，包括趋势分析、主题挖掘、引文网络分析和协作网络分析，并通过定性综合进一步增强。研究发现：（1）这两个研究领域在经历了孵化期和新兴期后，在2010年前后进入了快速发展期;（2） 景观可持续性研究主要集中在不断变化的景观中的生物多样性-生态系统功能-生态系统服务-人类福祉关系，而土地可持续性研究主要集中在土地利用和土地覆盖变化的原因、动态和影响，以及可持续的土地利用和管理;（3） 这两个领域之间的交叉引用很少见，这反映了两个科学界之间的互动薄弱。因此，尽管一些跨学科团队和个人研究人员已经开始在这两个领域开展合作，但景观可持续性和土地可持续性作为两个研究领域，在很大程度上仍然相互独立。 为了加强它们的协同互动，我们建议来自两个领域的科学家和从业者促进联合专业组织和会议，并共同促进广泛的合作项目，以在理论和实践中提高景观和地区的可持续性。
