气候变化背景下鄱阳湖南矶湿地子湖泊水位变化对越冬候鸟多样 性的影响

open access: yes野生动物学报, 2018
为了解在气候变化背景下鄱阳湖南矶湿地子湖泊水位变化对越冬候鸟的影响,本研究于2015年的10月、11月、12月与2016年的1月、2月、3月对鄱阳湖南矶湿地东湖口、白沙湖、战备湖3个子湖泊内水位及越冬候鸟进行监测与分析。结果表明:共记录到鸟类9目14科32种,其中冬候鸟23种、冬夏鸟和夏候鸟各3种、旅鸟2种、留鸟1种; 不同月份不同子湖泊鸟类群落的多样性、均匀度指数和优势度指数存在一定的动态变化,不同月份的鸟类多样性指数和均匀度指数均为3月>11月>1月>12月>10月>2月 ...

Embracing the politics of transformation: Policy action as “battle‐settlement events”

open access: yesReview of Policy Research, EarlyView.
Abstract Societal transformations for addressing climate change are intensely contested and at risk of resistance and backlash to ambitious policy action. But they are frequently modeled through heuristics such as S‐curves which abstract from such conflicts, assuming increasing returns to scale as a driver of transformations.

Influence of the greenhouse meteorological factors on the spring wild rice cultivation and management(大棚设施气象因子对春茭栽培的影响及管理)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2014
通过对棚内外春茭温、湿、光等气象因子的观测和对比,并对大棚内外春茭的物候期、经济性状、产量与效益进行了比较,得到受灾害性天气影响时棚内外的气象指数,提出了相应的应对措施.研究棚内气象因子变化的规律,以制订大棚规范化管理模式,实施对大棚的调控管理,为推广大棚栽培茭白提供示范和技术服务.

Turn to the right, turn away from the green?—A nuanced analysis on how a populist radical right party affects environmental policy making in Sweden

open access: yesReview of Policy Research, EarlyView.
Abstract Populist radical right parties are on the rise all over Europe. Recent literature investigates their effects on environmental policy, however, often applying an overly broad perspective on the policy area and neglecting causal mechanisms. This article addresses both gaps in an in‐depth case study of partisan effects on Swedish environmental ...

The role of solar radiation and atmospheric circulation in the seasonal temperature changes of Qinghai-Tibet plateau(太阳辐射和大气环流在青藏高原气温季节变化中的作用)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
利用1981~2010年共30 a的美国国家环境预报中心(NCEP)再分析格点资料,对青藏高原及其周边温度的季节变化及可能机理进行了研究.发现:地表24 ℃等温线2~3月和11月的南北跳动可能是太阳辐射和季风环流共同作用的结果;200 hPa温度的季节变化早于地面和500 hPa,其原因可能与平流层爆发性增温造成的能量下传有关;青藏高原的低温与低的大气逆辐射密切相关.该结果可为进一步研究青藏高原气候变化及其规律提供参考.

Comparing public support for alternative climate policy designs: An experimental study

open access: yesReview of Policy Research, EarlyView.
Abstract Scholars have debated how specific policy designs may generate stronger positive or negative reactions from the public, especially with regard to public expectations regarding pricing‐based policy designs compared to regulatory approaches.

World‐wide impacts of climate change and nitrogen deposition on vegetation structure, composition, and functioning of shrublands

open access: yesNew Phytologist, Volume 247, Issue 3, Page 1117-1128, August 2025.
Summary Environmental changes and their effects are among the most pressing topics of today's ecological research. Shrublands, although widespread across the globe, remain understudied in this respect. We conducted a global meta‐analysis of 81 shrubland sites subjected to experimental warming, shifts in precipitation (e.g.

环境因素对丹顶鹤越冬行为的影响

open access: yes野生动物学报, 2006
丹顶鹤在盐城越冬期间各种环境因素对其行为都将产生一定的影响,对此我们进行了观察记录。该项工作主要用8×40、10×50双筒和20倍单筒望远镜实地观察、照相机摄影等直接记录丹顶鹤的各种行为;种群数量计算为直接计数法;气候因子则根据各级气象部门的预报结果,结合观察点温度计等手段测算。结果表明丹顶鹤越冬期间,气候因子的变化是对其行为产生直接影响的主要因素,温度、雨、雾、雪、风等发生大幅度变化时,都将导致越冬期丹顶鹤的行为发生相应的适应性变化,对迁徙行为的影响则更为明显 ...

Impact of meteorological factors and control measures on the spread of COVID-19 epidemic(气候因素与控制措施对COVID-19疫情传播的影响)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
COVID-19疫情的暴发对医疗机构、社会和经济带来了前所未有的挑战,因此有必要了解影响该疾病传播的潜在因素。首先,采用统计描述获取COVID-19日新增病例数和气候因素的时空分布特征。然后,基于纵向数据的Poisson回归模型和广义估计方程(GEE),研究了COVID-19病例数与气候因素、控制措施和人口密度之间的关系。结果表明,影响COVID-19疫情的因素是多方面的,控制措施对COVID-19疫情的影响最为显著,其次是平均温度、平均相对湿度、平均露点、气候因素的长期趋势和季节变化 ...

Pollen morphology, deep learning, phylogenetics, and the evolution of environmental adaptations in Podocarpus

open access: yesNew Phytologist, Volume 247, Issue 3, Page 1460-1473, August 2025.
Summary Podocarpus pollen morphology is shaped by both phylogenetic history and the environment. We analyzed the relationship between pollen traits quantified using deep learning and environmental factors within a comparative phylogenetic framework.
