自“文化空间”一词开始出现在人类学领域之后,学界纷纷借用这一概念来探讨传统的或民间的文化表达方式。文化空间也是非物质文化遗产的一种重要形式,在人们理解文化的理论和实践中占据了重要地位。基于文化空间的重要性,我们选择哈尼梯田作为研究对象,探讨哈尼梯田的文化空间构成、活态性特征、社会性表述。通过探讨,我们发现哈尼梯田文化空间是在哈尼人利用自然环境构建农耕场所中形成的,是哈尼人生存实践的产物。这一特征也使哈尼梯田文化空间脱离了作为生产场所的局限而成为活态性文化,与哈尼人生活紧密联系在一起。同时,梯田文化空间作为社会性表述将哈尼人凝聚在一起,让哈尼人可以在其中找到自己的身份和地位,成为被群体认可和接纳的社会成员,使每一个成员都能够借此感受到民族凝聚的力量。这正是哈尼梯田文化空间所体现的意义和价值。

1985年8月23日发生在新疆维吾尔自治区乌恰县境内的M_(w)6.9地震,是有地震仪器记录以来,帕米尔-南天山会聚带内发生的最强地震事件之一,也是碰撞造山带前陆地区少数形成显著地表破裂的强震事件之一.在前人研究工作基础上,我们通过对震后Worldview卫星影像、无人机影像、野外调查获得的天然断层露头和人工探槽断层剖面的综合分析,对乌恰地震地表破裂的几何形态、变形样式、下伏断层结构进行了约束.研究表明,地表破裂东段呈弧形展布,其走向、运动性质和下伏断层倾角变化显著;相比较而言,西段虽因后期地表过程改造而非常不连续,其运动性质、走向和下伏断层倾角却更为稳定.由于地表破裂东、西两段分别位于明尧勒背斜南翼向形枢纽的南、北两侧,我们推测这种变形特征的显著差异,可能与向形枢纽两侧先存构造(先存的明尧勒背斜褶皱变形过程中形成的弯滑断层)的发育情况不同有关.

基于流动性理论,采用案例分析、归纳推理等方法,对资本作用下大都市区旅游空间结构的演化过程和形成机制进行研究。在构建理论分析框架的基础上,以南京都市区为案例地进行实证研究。结果表明:①大都市区旅游资本具有显著的流动性,其在不同时期分别呈现出“进城—出城—下乡—跨界”的流动特征,资本流动促进了流入地域内的旅游发展。目前,大都市周边的乡土-生态、跨界地区已经成为旅游资本流动最活跃的区域。②资本流动促进了重点旅游项目建设,推动了大都市区旅游空间结构演化,导致都市旅游地在不同时期分别形成了“核心-边缘”“多节点-链式”“链式+乡村斑块”“链式+旅游飞地”等空间结构模式,并呈现出“中心化—多中心化—离心化—边缘化”的总体演变趋势。③“流动”是资本突破都市区空间限制,不断向上发展的重要手段,旅游资本在“流动—固化—再流动—再固化”的发展路径上循环往复,通过与其他生产要素相互融合,共同促进了都市旅游地的空间结构演变和游憩功能完善。通过上述研究,验证了该理论框架的科学性和可行性,同时,总结了当前都市旅游空间结构演变的新特征、新趋势,论证了资本流动对都市旅游发展的作用机制,深化了对都市旅游空间结构演化的理论认识。最后,文章还讨论了资本流动作用下,大都市区旅游空间结构演变面临的风险与挑战,并对都市旅游的未来发展与管理提供了对策建议。

比例连带责任是由司法实践发展形成的一种新型责任形式,同时也是一种价值冲突的利益衡量过程。“半叠加分别侵权行为理论”和“比例原则理论”是比例连带责任的法理基础,二者可为比例连带责任的效果正当化提供解释力。随着司法实践中比例连带责任的扩张适用,可通过法律解释方法将其纳入《民法典》第一千一百七十一条之“连带责任”体系中作为一种子类型,解决比例连带责任之请求权基础的问题。“责任比例”的确定应根据原因力、过错程度、行为性质等因素综合认定,在对外关系上,各行为人承担的是中间责任;而内部最终责任比例应在外部责任基础上再次重新确定,各责任人之间可以相互追偿,实现侵权法填补损害与公平正义的价值目标。
