After the Yutian M_S7.3 earthquake,the authors instantly collected 1Hz high frequency data of the 4 reference stations within 350 km around the epicenter,and calculated the GNSS data with the TRACK module. The results showed that:( 1) The co-seismic displacement of Yutian station,about 54 km from the epicenter,is the most obvious,particularly in the EW component,with a change of about 52.5 ± 11mm,which is more than three times the mean-square error of calculating precision.( 2) In the Yutian reference station,the biggest variation in the EW component appeared within 1 minute after the earthquake.( 3) The change in the NS component is not great.

在中国制度背景下,乡村旅游的发展与政策变迁紧密相关。论文采用多变量交互作用的清晰集定性比较分析(csQCA)方法,基于多源流理论探索乡村旅游政策变迁的动力机制,分析由组织/领导变更、乡村规划政策变更、本地文化政策变更、东道主居民参与以及旅游市场舆情组成的乡村旅游政策变迁影响的构型。研究发现:(1)单项因素影响中,组织/领导的变更对文旅局层面的旅游政策出台产生了更大的影响力,东道主居民参与在市级政策

围绕油气资源的权力博弈仍然是当今世界最主要的能源权力争夺,但不同时代的能源权力的属性有所不同,能源安全与能源战略内涵也有所不同。论文在系统梳理能源地缘政治基础上,提出了能源权力的概念,并从地缘政治格局、能源安全观、能源网络和全球能源治理4个方面进行了具体阐述。研究认为:(1)以能源分布、产销空间变化及其规律性总结是传统能源地缘政治研究的核心,油气资源地理分布的不平衡性是能源权力产生的最直接因素。(
