始自行为革命,行为地理学逐渐走向多元化的发展方向,不断扩展自身的理论框架和实践外延,反思并重新认识自身的意义,成为了人文地理学的重要组成部分.伴随着社会经济转型的深入,世界越来越向着多样化、个体性、动态化发展,人们的空间行为决策、选择的差异与个性越来越明显,空间与行为的交互越来越强,为行为地理学带来了新的发展机遇.论文通过梳理行为地理学的学科基础,提出行为地理学的学科定位与内涵外延,并指出行为地理学已经呈现出面向动态人地关系、面向个体生活质量及面向社会可持续发展3个前沿发展方向.在此基础上,论文对行为地理学面临的方法论、研究方法与跨学科的挑战进行讨论,并展望行为地理学的未来发展,以期为中国行为地理学的理论创新与实践探索提供启示.

最近在玛湖凹陷斜坡区上三叠统白碱滩组砂体内钻遇工业油流,但其沉积成因还未见报道.以玛西斜坡区为研究范围,在岩心沉积特征观察、镜下岩矿成分分析及粒度分析等基础上,结合测、钻井资料等,对白碱滩组沉积相类型进行鉴定,并阐明沉积演化规律.结果表明:白碱滩组内包含辫状河三角洲和湖泊两个相类型,并可进一步细分出辫状河三角洲前缘、前辫状河三角洲及浅湖共计3个亚相类型,以及水下分流河道、河口砂坝、远砂坝、浅湖砂坝等7个微相类型;纵向上,自白一段到白三段,表现为自浅湖亚相到辫状河三角洲前缘亚相的连续过程,演化规律十分清楚.
浪控三角洲砂体是海陆交互带沉积有利的油气储层和勘探目标,目前业界对其微相划分、沉积机理和沉积模式研究较少.以巴基斯坦N区块为例,依据岩心、测井、地震及分析测试资料,开展受波浪改造作用的海相三角洲沉积相带划分、展布及沉积模式研究.结果表明:综合大量沉积相标志分析,研究区白垩系处于砂质高能海岸带,三角洲入海口受到强烈的波浪、沿岸流和风暴浪的改造、破坏和再分配作用,形成浪控三角洲沉积,表现为沿平原亚相向海洋延伸的环岸砂坝发育带.其格架相与建设性三角洲明显不同,水下分流河道和河口砂坝不发育,在河口两侧形成滩砂复合

Wireless power transfer (WPT) technology is a popular choice for biomedical implant devices. The demands of higher efficiency and smaller implantation size are hard to compromise in previous studies. In the present work, an implantable magnetic coupling r
This paper proposes a novel flexible antenna design operating at very high frequency (VHF) band for on-body applications such as human body communication (HBC). The antenna consists of back-to-back E-shaped fractal and complimentary structures designed ov

Hyperthermal environments can harm workers\' health and safety. However, it is difficult to include effective protection into standards because heat-related impacts vary significantly accord-ing to individual workers and multiple factors. Studies sugges

The body channel based wireless power transfer (BC-WPT) method utilizes the human body as the medium to transfer power for bioelectronics, which can achieve a lower transmission loss due to its higher conductivity. However, except for the channel length,
