Evaluating protected areas’ coverage of threats to terrestrial biodiversity
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Protected areas (PAs) are vital for biodiversity conservation and have expanded globally. However, increasing pressures on biodiversity make it difficult to achieve conservation goals. Using threat probability maps based on the International Union for Conservation of Nature Red List and the World Database of Protected Areas, we analyzed the ...

Shuitu Baochi Xuebao, 2003 认为土地整理改变着土地利用/覆被变化(LUCC),并进而对其优化调控.而同时土地整理又需要土地利用/覆被变化的研究提供技术支持.加之县域土地整理是区域乃至全国土地整理目标和方向在时空推进上的具体落实,是检验和评价区域土地整理效果和跟踪监测的有效场地.因此,本文以重庆市万州区为例,就县域土地整理与土地利用/覆被变化变化作以探讨.

Hydro‐Insurgency: Weaponization of Water Resources and Infrastructure in Northeast Syria
World Water Policy, Volume 11, Issue 4, Page 924-938, November 2025.ABSTRACT This article examines the strategic weaponization of water resources by Turkey‐backed armed groups in Northeast Syria (NES) within the broader context of the Syrian civil war. As the conflict evolved, water infrastructure—dams, rivers, and irrigation systems—became central to warfare, governance, and foreign agendas. The article introduces the

Shuitu Baochi Xuebao, 2004 以黄土丘陵区纸坊沟流域为研究区,对其60年来的土地利用格局变化进行系统的分析研究,结果表明,土地利用格局变化与人类活动密切相关。农业用地的扩张,是导致林草植被破坏和土地利用格局变化的重要原因。从1938～1958年,坡耕地在土地利用格局中的优势度由低到高,而林草植被的优势度则降至最低点。之后,林草植被随着坡耕地的变化经历了缓慢变化期(1958～1973年)和较快增长期(1973年后)。其中1958年和1995年,是土地利用格局的质变点,也是生态环境变化的重要转折点 ...
