基于公民科学数据分析环志水鸟迁徙连接——以广西北部湾沿海地区为例

野生动物学报, 2023
广西北部湾沿海地区为东亚—澳大利西亚候鸟迁徙通道上的重要迁徙停歇地。基于公民科学数据，分析广西北部湾沿海地区记录到的异地环志水鸟与其越冬地、繁殖地及其他停歇地的迁徙连接。结果表明：2020年1月—2021年12月，广西北部湾沿海地区记录到澳大利亚塔斯马尼亚州、俄罗斯楚科奇及中国江苏等11个地点环志的10种水鸟，共计38只，其中，记录到数量较多的种类有勺嘴鹬（Calidris pygmaea）、铁嘴沙鸻（Charadrius leschenaultii）和大凤头燕鸥（Thalasseus bergii ...

Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

Integrative Conservation, EarlyView.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

南北地震带北段的地壳速度结构及其构造启示

Dizhen xuebao, 2018
收集和拾取了“中国地震科学台阵”探测项目在南北地震带北段布设的680个流动地震台站和中国地震台网217个固定台站所记录的地震事件的P波和S波初至到时，通过层析成像研究获得了南北地震带北段水平网格间距为0.33°×0.33°的地壳P波和S波速度分布。结果显示：在30 km深度上青藏高原东北部表现为显著的整体性低速异常，低速异常区向南延伸至龙门山断裂，以106°E为界线将秦岭造山带分为西侧的低速异常和东侧的高速异常，并沿银川—河套地堑向东北展布，向北穿过河西走廊，在阿拉善地块表现为低速异常 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

Conservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

基于USLE的甘南川西北土壤侵蚀研究

Shuitu Baochi Xuebao, 2021
甘南川西北位于黄河和长江上游源区，量化研究该区土壤侵蚀对河源区生态安全保障和地方经济可持续发展具重要意义。论文采用多种数据方法，基于USLE就甘南川西北2000—2015年间土壤侵蚀的时空分布特征及变化规律进行量化评估。结果表明：（1）降雨侵蚀力因子R值介于65~411（MJ·mm）/（hm2·h·a），高值区主要分布在东南部，空间分布与该区降雨格局基本一致；（2）土壤可蚀性因子K值介于0.19~0.41（t·hm2·h）/（hm2·MJ·mm），高值呈斑块状零星分布，与地带性土壤物化性状有关；（3 ...

Harnessing social media data to track species range shifts

Conservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

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

CHINA’S LAND FINANCE AS ACTIVE MODE OF LAND DEVELOPMENT AND INFRASTRUCTURE DELIVERY: Reality, History and Prospects

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.
Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...
