People and Nature, EarlyView.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 采用地统计学的方法,研究了江西泰和退化红壤区不同模式重建森林在高温干旱季节土壤水分空间变异规律及其分布格局。结果表明,在该研究尺度下,湿地松纯林、枫香纯林、湿地松与枫香混交林0~20 cm,20~40cm土层含水量分布都符合正态分布,都可较好地拟合成球状模型,表现出明显的空间相关性和空间分布格局。3种重建模式样地0~20 cm,20~40 cm层土壤含水量变异函数的基台值、变程都较无林荒地明显增大,而且基台值和变程在0~20 cm,20~40 cm两土层间的差异明显大于无林荒地,说明植被恢复以后 ...

Rare Metals, EarlyView.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Simulation and Prediction of Xiamen Urban Expansion Based on A Coupling Relationship Between Land Use and Transportation [PDF]
, 2016 在经济新常态和新型城镇化战略不断推进的时代背景下，中国城市空间结构发展模式的转型已势在必行。在经历了长期的外延式城市空间快速扩张之后，人口和资源环境的矛盾、建设用地的紧张、交通供给与需求的脱节等成为我国城市空间发展中一系列不容回避的问题，城市空间由外延式扩张向内涵式提升的转型已经迫在眉睫。厦门市可建设用地的稀缺将对城市规模的扩张构成直接限制，但同时，在过去几十年的快速城市化进程中，由于缺乏对城市空间政策和公共投资的有效整合，城市空间增长有明显的分散化迹象 ...
