Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Chemically self‐charging aqueous zinc‐ion batteries (AZIBs) have emerged as promising candidates for energy storage technologies owing to their environmental autonomy and structural simplicity. Nonetheless, the self‐charging performance is significantly compromised by the limited potential difference between cathodes and oxygen, as well as the

Shuitu Baochi Xuebao, 2003 利用地统计学和地理信息系统相结合的方法研究了沈阳市郊耕地1991个样本0～20cm耕层土壤交换性铁含量的空间异质性特征，绘制了交换性铁含量的空间分布图，结果表明，土壤交换性铁含量基本符合正态分布，变异函数的最佳理论模型为球状模型，交换性铁含量具有中等的空间相关性（Co与Co C比值为41.3%，空间自相关距离为34.9km），Kriging内插图显示出交换性铁具有较强的空间质异性，其空间异质性主要受成土母质，成土过程和土壤类型等结构性因子的影响。

Wildlife Letters, Volume 4, Issue 1, Page 10-22, March 2026.In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

Shuitu Baochi Xuebao, 2007 用经典统计分析和地统计学的方法，对中国生态系统研究网络（CERN）临泽站新设置的农田生态系统综合观测场土壤性状的空间分布特性进行研究。结果表明，除pH外，土壤有机碳、全N、速效养分和电导率的变异性均超过20％，有机碳和全N的空间相关距离为13．8m和12．6m，表现出较高的空间异质性。克里格插值结果同样显示土壤各性状在研究的尺度上有明显的空间变异格局。相对误差为10％时采集124个土样才可达到95％的置信水平。作为生态网络长期监测样地，必须按空间异质性对观测场地进行采样分区、匀地过渡 ...

Shuitu Baochi Xuebao, 2006 利用地统计学方法，在两个尺度下对蘩顶山茶园土壤颗粒组成的空间变异性进行了研究。结果表明：（1）小尺度下土壤颗粒组成各粒级均具有强烈的空间相关性．其中粘粒的空间相关距最大．粗粉粒的空间相关距最小；土壤颗粒组成各粒级主要在东、东南和东北3个方向上具有较强的空间变异，除砂粒外的其它颗粒均在东南方向空间变异明显；各粒级的空间分布没有明显的规律可寻。（2）微尺度下只有粘粒具有强烈的空间相关性，砂粒具有中等空间相关性，其余粒级空间相关性很弱，粘粒空间相关距最小；除砂粒外的其它粒级在东南方向具有明显的空间变异 ...

Shuitu Baochi Xuebao, 2011 采用经典统计学和地统计学方法分析了小兴安岭阔叶红松混交林林隙表层土壤(0-10cm)养分空间变异结构及其分布格局。结果表明:土壤pH值(CV=5.28%)和速效钾(CV=7.33%),呈弱变异性,其他土壤化学指标均表现为中等程度变异。土壤pH值、有机质、全氮、全磷、铵态氮、硝态氮、有效磷和速效钾变异函数曲线的理论模型符合球状模型。土壤养分的空间变异主要是由结构性因素引起的,且空间自相关程度均属中等(空间结构比均在25%以上)。克里格法插值估计和各养分属性的等值线图表明 ...

Mycorrhiza‐induced alterations in the spatial structure of stands in a subtropical forest
Functional Ecology, Volume 40, Issue 3, Page 668-678, March 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Spatial aggregation patterns represent snapshots of ecological processes that occurred over an extensive period. Such processes can shape both the conspecific and the heterospecific spatial structure of plants across woody habitats.

Antipode, Volume 58, Issue 2, March 2026.ABSTRACT Drawing on Rancière's “politics of aesthetics,” this paper frames digitally facilitated gentrification as a battleground for visibility and associated value extraction between different stakeholders and investigates how aesthetic sensibilities are redistributed through social media.

Shuitu Baochi Xuebao, 2005 采用地统计学与经典统计学相结合的方法,对中国科学院沈阳生态实验站长期定位试验地耕层土壤全N和碱解N空间变异性特征进行分析的结果表明,在30m×42m的田间尺度下土壤全N和碱解N在0～10cm和10～20cm两个层次的空间变异主要受结构性因子的影响,在135°方向的变异相对较强,说明观测试验地较为均一的田间管理使得随机因子引起的空间变异所占比例大大减弱。根据变异系数和分形维数分析结果,可以认定试验地能够达到长期定位监测的要求。相对误差为5%时采集17个和29个土样可分别达到95%和99%的置信水平 ...
