Spatially Downscaling of Future Food Demand for Policy Planning
World Food Policy, Volume 12, Issue 1, May 2026.ABSTRACT Understanding the subnational dynamics of food demand, while accounting for the evolution of the agrifood system at the global level, remains a challenge for designing food policy to ensure food security. To link global agrifood systems with subnational food policy planning, we downscale per capita food demand for 62 food commodities at the ...

People and Nature, Volume 8, Issue 3, Page 741-753, March 2026.Abstract Currently, scholarship on education to foster connectedness with nature primarily focuses on children. As adults likewise face the disconnection from nature and play a key role in influencing children, it is important to understand how they perceive, engage in, and benefit from relevant programmes.

Shuitu Baochi Xuebao, 2007 采用地统计学的变异函数分析方法，定量研究了14年生水曲柳人工林表层土壤（0～10cm）养分的空间异质性特征。结果表明：（1）土壤有效磷、全钾和速效钾变异函数曲线的理论模型符合指数模型，土壤pH值符合球状模型，土壤全氮、水解氮和全磷的理论模型符合指数模型或球状模型；（2）土壤养分各项指标的空间变异主要是由结构性因素引起，且空间自相关程度均属中等以上（空间结构比均在25％以上）；（3）土壤pH值的空间自相关范围最大（2．27～4．46m），土壤全磷的自相关范围（0.73～0．97m）小于全钾和全氮（分别为1．

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

耦合生态系统服务供求关系的生态安全格局动态分析——以闽三角城市群为例 [PDF]
, 2018 实现分区管理是缓解城市群生态安全空间差异的有利途径。基于供求理论构建了生态系统服务供求关系动态模型框架,并利用供给与需求的象限区划表征闽三角城市群生态安全格局;在不同的尺度变换上,运用价值单量修正模型、INVEST生境质量模型、景观指数模型、生态韧性模型、熵权法等方法综合测度城市群生态系统服务供求水平,实现生态安全格局的分区化;引入环境库兹涅茨曲线理论解析区域生态安全格局现状和成因;数据分析借助Arc GIS可视化表示。研究发现:(1)闽三角城市群存在50%区域属于生态安全高供给失衡区,其中70 ...
