Shuitu Baochi Xuebao, 2006 以宁夏盐池县为研究对象，以4期卫星遥感影像为数据源，应用遥感、地理信息系统及景观生态学原理，在获取大量数据的基础上，采用定量的方法深入分析了研究区的景观格局状况。结果显示，在研究时段内盐池县土地景观空间格局发生了显著变化，整体景观的破碎度和多样性指数在不断上升，优势度指数不断降低，均匀度指数持续增加，景观格局朝着农、林，牧多优势度的趋势良性发展。盐池县生态环境状况正在逐步得到改善。

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。

Mountains Without Borders: Scaling up Conservation Success for Snow Leopards
Integrative Conservation, Volume 5, Issue 1, Page 1-4, March 2026.This special issue assembles pioneering research addressing three critical and interconnected challenges: establishing where viable populations persist at range edges, advancing methods to monitor this cryptic species and its prey effectively, and evaluating whether landscapes remain connected across political boundaries.

Shuitu Baochi Xuebao, 2023 针对喀斯特地区景观格局驱动水源涵养功能演变机制的相关研究较少,而水源涵养功能是岩溶石漠化治理等生态修复工程生态效益的关键指标之一,具有重要的研究意义。以地处西南喀斯特中心的野纪河流域为研究对象,基于InVEST模型、偏最小二乘模型(PLSR)、景观生态学理论等,探究野纪河流域2005—2020年水源涵养功能的时空分异特征及其与景观格局的耦合关系。结果表明:(1)野纪河流域景观类型以旱地、草地和灌木林等为主,各类型之间相互转化较为频繁,总体特征表现为旱地、灌木林和草地之间的转化以及建设用地对其余地类的挤占。

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Urban expansion significantly impacts flood risk, particularly in rapidly growing areas where impervious surfaces exacerbate surface runoff. This study examines spatial patterns of urban growth and their effects on flood exposure in Mecklenburg County, North Carolina, from 2011 to 2021.

Shuitu Baochi Xuebao, 2022 为进一步明确流域河岸带景观尺度范围差异性及对河流磷(P)输出的影响,量化解析河岸带尺度下景观与河流P之间的关系。以亚热带典型农林混合流域为研究对象,基于长期水文、水质监测数据,利用冗余分析明确不同河岸带尺度景观格局特征与不同水文季节河流P浓度的关系,并采用变点分析量化导致丰水期、平枯水期河流P浓度突变的核心景观指数的阈值范围。结果表明:(1)河岸带景观格局对河流P浓度的影响具有显著的空间尺度性特征,300,400 m分别是影响丰水期和平枯水期河流磷浓度变化的关键临界尺度。(2 ...

Shuitu Baochi Xuebao, 2002 荒漠绿州景观格局是不同类型、不同大小、不同形状和不同开发程度的地块（生态系统）在空间上构成的镶嵌体。景观镶嵌结构的差异反映出不同的功能，通过计算一些景观指数，对荒绿洲景观格局作出定量分析。人类活动强烈的景观要素或纯粹的人工景观中，表征复杂的景观指数往往高于人类活动较轻的景观要素，而表征稳定性的指数正好相反；处在干旱内陆荒漠中的绿洲景观，其抵抗外来干扰的能力低，恢复力弱，人类不合理的活动极易破坏其稳定状态，从而导致荒漠化发生。

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little
