Stages on Journeys: Some Remarks about Human Geography andPsychotherapeutic Practice

This paper attempts to open up discussion about interconnectionsbetween psychotherapeutic practice and human geography. I offer brief “here and now” observations to introduce the importance of personal experience and interpersonal relationships. I then construct an autobiographical narrative to elaborate the themes of separation and connection. This frames my preliminary explorations of tensions and convergences between ideas flowing from psychotherapeutic practice and human geography. I conclude by stressing limits to knowledge.

应对气候变化与保护生物多样性协同：全球实践与启示

气候变化与生物多样性丧失是当前全球面临的两大热点和难点环境问题,二者协同推进的必要性和重要性也在全球范围内形成广泛共识。文中在总结我国“双碳”目标下应对气候变化与保护生物多样性协同的现状与挑战的基础上,对近年来各国应对气候变化和保护生物多样性协同方面的政策实践进行了系统梳理与总结,各主要国家近年来在战略规划、生态空间、绿色金融、科技创新等方面进行了大量实践探索以推动二者协同,在这些实践推动下,全球已逐渐将“碳中和”和“生物多样性”融入生态环境治理新格局、将基于自然的解决方案（NbS）作为二者协同领域最有效的新路径、将绿色金融和科技创新作为推动二者协同发展的新动力。鉴于此,我国在二者协同推进中亟需将生物多样性保护纳入双碳“1+N”政策体系,注重将基于自然的解决方案融入城镇化、乡村振兴等重大国家发展战略,鼓励引导绿色金融、数字科技支持二者协同的重点领域,提高公众认知和社会参与,以推进二者协同并助力我国成为全球生态治理的重要参与者、贡献者和引领者。     

几何不等式问题的推广及应用

本文对几何不等式问题做些推广，并提出了广义几何不等式，通过构造随机变量，利用随机变量数学期望的概率性质，给出几何不等式及广义几何不等式的概率证明，最后给出几何不等式的一个直接应用，所得的结果是文献（１－４）的补充和拓广。     

Place and Health: Towards a Reformed Medical Geography*

An engagement with public health concerns and aspects of social theory such as the structure/agency debate is crucial to medical geography. The imperatives underlying this engagement center on place, a geographical concept which is prominent in both social theory and recent health philosophy. Without detracting from its distinguished heritage, this reformed medical geography will analyze issues such as the consequences of illness and health service provision for both personal well-being and the collective experience of place by communities.

基于方法-目的链的沙漠型旅游区体验特征分析：以库木塔格沙漠旅游区为例

旅游体验是丰富的、多层次的,游客获得的体验随旅游类型差异而不同,现有研究缺乏对沙漠旅游体验的深入探讨。为探索沙漠旅游体验的复杂性和层次性特征,以库木塔格沙漠旅游区为例,运用方法-目的链（means-end chain,MEC）理论及软式阶梯访谈法,辅以网络文本分析,构建属性-结果-价值关联矩阵,绘制沙漠旅游区体验的层级价值图。研究识别出6条方法-目的链,最重要的是MEC1（自然风光-开拓视野/新奇体验-满足感/美好回忆）,充分体现了沙漠旅游区因其浩瀚无垠的独特景观,让游客开阔眼界、满足好奇心,使其留下美好回忆、获得满足感。研究结果不仅从方法论视角丰富旅游体验研究,而且能为沙漠旅游的健康持续发展提供启示。     

浅谈长三角地区典型地市防震减灾工作成效、困难与解决对策

海宁硖石地震台位于浙江海宁市硖石街道西山公园人防山洞内,该台在建设过程中,不但面临岩石体质量差的问题,洞室地面下挖至2 m以上深度,岩石依旧呈现多气孔且破碎的状态;还面临洞室湿度高的问题（>95% Rh）。最终在不可能采用岩石墩建台的情况下,通过浇筑大面积混凝土仪器墩,并对洞室环境进行改造,降低洞室湿度,做到保温、恒湿,改善观测环境。至今,该台已有十多年的运行时间,从目前情况看,台站观测数据平稳连续,固体潮清晰,达到了台站改造的预期效果。本文通过总结海宁硖石地震台在改造过程中取得的经验,为在一些不具备建造岩石墩的人防、民用山洞内,建设地形变观测台提供借鉴。
