World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Prospects and perils in the geospatial turn of conservation
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Conservation has embraced advances in big data and related digital technologies as key to preventing biodiversity loss, especially in the identification of areas of conservation priority based on spatial data, which we call the big geospatial data turn.

Evaluation of the Up-to-date Approach SBA for Measurement of Water Leaving Radiance [PDF]
, 2015 SBA(Skylight-blockedapproach)是新近提出的直接测量离水辐亮度Lw的方法(Leeetal.,2013)。该测量方法是由表面之上法改进而来。辐亮度光谱仪镜头处安装上一个蔽光元件——遮光锥，测量时遮光锥的末端稍稍插入水中但光谱仪镜头保持在水面之上。如此一来，遮光锥将水面反射的光完全阻挡，来自水中的辐亮度穿过水面后自然转变为Lw并被光谱仪所接收，从而实现了由光学传感器直接获得Lw的突破。传统的测量方法，包括剖面法和表面之上法，只能测量相关参数，然后通过物理模型计算得到Lw。然而 ...

Towards a global understanding of tree mortality
New Phytologist, Volume 245, Issue 6, Page 2377-2392, March 2025.Summary Rates of tree mortality are increasing globally, with implications for forests and climate. Yet, how and why these trends vary globally remain unknown. Developing a comprehensive assessment of global tree mortality will require systematically integrating data from ground‐based long‐term forest monitoring with large‐scale remote sensing.

Integrative Conservation, Volume 3, Issue 2, Page 142-147, June 2024.In the process of integrating and optimizing of nature reserves in China, preserving farmland would increase the exposure level and decrease the maximum depth of nature reserves. Abstract Spatial contradictions between nature conservation and social development are prominent in the integration and optimization of nature reserves (NRs) in China.

Research of Retrieving Sea Surface Wind Vectors Based on Sentinel-1A Satellite SAR Images [PDF]
, 2016 海面风场是海气交互界面的重要物理参数，与海洋中绝大多数的海水运动密切相关。海面风场还是海气相互作用的重要媒介，调节了海水和大气之间的物质以及能量输送，对全球气候调节也有着十分重要的作用。 船舶、浮标等观测手段花费高昂，加上海洋面积巨大，可获得的现场海面风场数据十分有限，很难满足大面积海面风场的观测需求。日益发展的卫星遥感技术，为大面积观测风场提供了可能，微波散射计已经成为大面积获取全球海面风场的最重要遥感手段之一，不过微波散射计的空间分辨率通常为25-50km，难以满足对高分辨风场的需求 ...
