Zhejiang Daxue xuebao. Lixue ban, 2018 青海省宗教发展历史悠久，宗教旅游资源丰富，宗教场所的空间分布特征对青海省区域旅游格局有重要影响.对青海省宗教场所旅游资源进行了统计，分别从空间分布模式、差异性、密度等方面采用最邻近指数、地理集中指数、洛伦茨曲线、核密度方法对其空间格局特征进行了定量分析，并利用空间回归分析法探讨了其分布与海拔、坡度、交通、水系等因素的关系.结果表明：青海省宗教场所旅游资源呈“东多西少”的集聚分布态势，空间差异显著，旅游资源集中在青海省11%地区；空间分布密度呈由东向西辐射（型）的分布趋势；空间回归分析结果显示，在地势平坦、

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Conservation Biology, EarlyView.Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal
Conservation Biology, EarlyView.Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, Volume 8, Issue 7, Page 2186-2199, July 2026.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Shuitu Baochi Xuebao, 2003 景观格局是地貌格局、土壤格局、植被分布格局、水资源格局及生产力格局等的综合.从景观发育的动力因素角度,分析了洮儿河中下游流域景观格局特征,总结了推动景观格局形成的地质地貌、气象水文及社会生产力因素,重点阐述了水环境系统演化与景观格局发育的耦合过程和特征,探讨不同景观要素对水环境特征分异的关系,分析景观格局对水环境系统中水量、水质及空间分布的整体影响.

Shuitu Baochi Xuebao, 2007 以重要水源地东圳库区的法国SPOT-5影像图和土壤侵蚀强度图为源数据,运用GIS的信息管理、空间数据处理分析功能,以土地利用景观为研究对象,提取景观空间格局特征信息,选取景观格局分析指标,对土地利用景观空间格局进行定量化研究,寻求一定的规律,探讨景观格局和水土流失过程之间的关系以及人类活动对景观格局和生态过程的影响。研究表明：库区景观类型和生态系统分布不均;随着侵蚀级别的增加,多样性指数减小,优势明显,均匀度降低;库区的园地和耕地景观破碎程度较大,是造成水土流失的主要原因。

Wildlife Letters, Volume 4, Issue 2, Page 94-101, June 2026.Although once abundant across its range, gray foxes (Urocyon cinereoargenteus) are purportedly declining. While range maps indicate that gray fox potentially occur throughout the central United States, contemporary distribution maps are needed. We developed a Habitat Suitability Model for six states, leveraging gray fox presence data in an ensemble ...

Shuitu Baochi Xuebao, 2022 准确识别土地利用格局时空演变规律和轨迹特征, 对科学推进该地区生态保护和社会经济高质量发展具有重要意义。采用1990年、2005年和2018年3期土地利用数据构建鄂西南地区土地利用变化轨迹序列, 利用土地利用变化各项指数、弦图可视化、标准差椭圆方法, 从地类总量变化特征、数量变化轨迹特征和空间变化轨迹特征3个方面开展, 揭示近30年来鄂西南地区土地利用格局时空演变特征与变化趋势。结果表明: (1)土地利用总量变化稳定性特征明显。林地和耕地始终是研究区主要土地利用类型, 耕地持续减少, 建设用地持续增加,

Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
