摘要

太平洋岛屿地区是世界上几个生物多样性热点地区的所在地,但其独特的动植物群正受到生物入侵的威胁。随着人类活动的增加和大规模自然干扰的出现,以及气候变化的加剧,这些入侵很可能会激增。遥感数据和技术提供了一种可行的方法来绘制和监测入侵植物物种,并为整个太平洋岛屿地区的入侵植物物种管理提供信息。我们利用从谷歌学术、3 个地区机构数字图书馆和 2 个入侵植物物种管理在线目录中检索到的文献进行案例研究,考察太平洋地区对遥感技术的吸收情况以及在实施过程中面临的挑战。我们对遥感技术进行了综合分析,并根据物种物候学、结构特征和图像纹理算法概述了这些技术在检测和绘制入侵植物物种地图方面的潜力。应用遥感方法检测入侵植物物种在很大程度上依赖于物种生态学、入侵范围以及可用的地理空间和遥感图像数据。然而,目前支持入侵植物物种管理的机制,包括政策框架和地理空间数据基础设施,都是孤立运行的,导致工作重复,为该地区创造了不可持续的解决方案。为使遥感技术支持该地区的入侵植物物种管理,包括保护管理人员、研究人员和从业人员在内的主要利益相关方、资助机构和地区组织必须尽可能投资于更广泛的地理空间和环境部门,整合和简化政策,提高能力和技术获取能力。

Capacity and capability of remote sensing to inform invasive plant species management in the Pacific Islands region.

The Pacific Islands region is home to several of the world's biodiversity hotspots, yet its unique flora and fauna are under threat because of biological invasions. These invasions are likely to proliferate as human activity increases and large-scale natural disturbances unfold, exacerbated by climate change. Remote sensing data and techniques provide a feasible method to map and monitor invasive plant species and inform invasive plant species management across the Pacific Islands region. We used case studies taken from literature retrieved from Google Scholar, 3 regional agencies' digital libraries, and 2 online catalogs on invasive plant species management to examine the uptake and challenges faced in the implementation of remote sensing technology in the Pacific region. We synthesized remote sensing techniques and outlined their potential to detect and map invasive plant species based on species phenology, structural characteristics, and image texture algorithms. The application of remote sensing methods to detect invasive plant species was heavily reliant on species ecology, extent of invasion, and available geospatial and remotely sensed image data. However, current mechanisms that support invasive plant species management, including policy frameworks and geospatial data infrastructure, operated in isolation, leading to duplication of efforts and creating unsustainable solutions for the region. For remote sensing to support invasive plant species management in the region, key stakeholders including conservation managers, researchers, and practitioners; funding agencies; and regional organizations must invest, where possible, in the broader geospatial and environmental sector, integrate, and streamline policies and improve capacity and technology access.

期刊介绍: Conservation Biology welcomes submissions that address the science and practice of conserving Earth's biological diversity. We encourage submissions that emphasize issues germane to any of Earth''s ecosystems or geographic regions and that apply diverse approaches to analyses and problem solving. Nevertheless, manuscripts with relevance to conservation that transcend the particular ecosystem, species, or situation described will be prioritized for publication.
