Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

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 ...

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.

Research on the spatial topological structure of Tourism traffic——take Xiamen city as an example [PDF]
, 2015 交通作为旅游产业发展的基础条件，一直是学者研究的重点。纵观旅游业发展史，每一次的历史性发展无不与交通技术进步紧密相关，交通布局合理与否直接关系到旅游产业的发展程度。厦门作为国际知名的海上花园城市，是我国著名的滨海旅游城市，也是东南沿海重要的交通枢纽，但也深受福建交通发展的制约。 交通系统作为一个复杂的系统，不同的结构体系呈现出不同的交通运输力。旅游交通既依附于大的交通体系，又有其特殊性，日常交通结构分析的方法无法简单系统、直观地反映出整个旅游交通网络结构体系的空间特征。因此 ...

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 ...

Research on The Choice of Rail Transit's Route Scheme of The Third Line in X City [PDF]
, 2016 轨道交通在国内发展非常迅速，很多城市在积极规划或扩建中。同时在持续快速城镇化的冲击时，我国很多城市在市级中心以外建立起了多个城市副中心，轨道交通线网串联起这些中心，承载着引导城市空间形态由高强度“单中心”向功能相互渗透的“多中心”空间结构转变。但面临在一个城市已经修建了既有骨架地铁线路穿越市级中心后，需要再次修建地铁线路时，其线路走向是采用中心到副中心方案还是副中心连接副中心方案的问题。 本人针对上述问题，以X市轨道交通第三条地铁线为研究对象，针对第三条地铁线两个备选方案的特点 ...

Industrial Upgrade Effects of Product Space Dynamic Evolution——in Case of China [PDF]
, 2016 保持一国经济持续发展，提高国民收入水平，是经济学界所关注的重要课题。现有的比较优势理论认为，发展中国家可以通过充分发挥其比较优势，实现专业化生产，依靠产业分工和专业化经济，推动要素禀赋的内生转换，从而实现国家生产技术结构的升级和调整，内生地达到产业结构升级、高级化、合理化，推动经济的持续增长。但是“中等收入陷阱”现象对该理论的合理性和科学性提出了挑战，为什么光靠比较优势实现的专业化生产，无法实现内生的产业结构升级和持续的经济发展？显而易见，在解释和回答这个现实经济问题方面 ...
