华北平原农村居民点演变及社会经济影响因素分析 总被引:8,自引:0,他引:8
基于遥感图像分类解译数据,利用位序-规模模型、洛伦兹曲线、景观指数,定量识别了2000-2015年华北平原农村居民点空间分布、规模与形态演变特征,分析了社会经济因素的驱动机制。结果表明:华北平原农村居民点南-北方向呈显著的空间分异与集聚特征,密度分布呈现南密北疏的态势,与面积规模分布存在局域负相关;农村居民点景观指数显示出密度增大、形状更加规则、斑块面积差异增大、斑块间邻近距离不断缩短的变化特征;总人口数量和乡村户数等对农村居民点用地扩张具有促进作用,乡村常住人口、乡村从业人员数量等的作用为负。 相似文献

唐人小说中,许多题材涉及到文士的隐居修业。我们以此为切入基点,来探讨文士的隐读模式,其反映出来的文化心理主要包括文士对婚姻与性爱的向往与追求、“以色当婚”的风习、好奇的时代风尚及文人“仕”、“隐”的矛盾性心态。此外,唐代“坟寺”风俗等寺院文化对文士的隐读也有一定的影响。 相似文献

There are many anecdotes and legends amongst Tibetans concerning encounters between human beings, bears and marmots. One of them tells of the merciful old monkey who married an ogress and she gave birth to three brothers. The elder one was a bear with a white chest. He lived on a mountain summit and looked strong and brave. The youngest was a yellow marmot with four short legs that enabled him to move easily in and out of an underground hole. The second one was human being, and treated as the family treasure because he was smart and ingenious. Naturally, he became the family master. 相似文献

在逐步确立自己文化学体系期间,陈序经曾倾心于社会问题的研究,积极参与包括民和华侨问题在内的西南社会的研究工作以及乡村建设运动的讨论。在西南社会研究中,他应用文化学方法,开展对民的调查研究,拟从中发掘出新的资料,印证西方文化学说,寻找文化发生、发展的一般法则;并宣传进步文化观,主张不同民族应共同发展。有关华侨研究本身是对文化主体的关注,其现实目的是为了保护华侨权益、激发华侨创造新文化的活力。在乡村建设运动的论战中,他以文化进步说、文化时境论、文化不可分论、文化动力论与文化中心论,反对复古趋向、以农立国说,主张立足都市,西化乡村。现实关怀则促使陈序经将其中零散的文化理论进一步明晰化、系统化。陈序经文化学与其社会问题研究之间存在着相辅相成、互相交融的关系。 相似文献

企业孵化器及其空间分析——以西安创业服务中心为例 总被引:5,自引:0,他引:5
企业孵化器在我国又称创业服务中心。在转化科技成果、孵化高新技术企业、培育企业家,以及推动区域经济的发展方面有巨大的贡献。本文分析企业孵化器特征及其与高新区的关系基础上分析了其空间区位选择、空间关系以及景观、经济、体制思想文化和生态等空间功能。在研究国外企业孵化器发展的基础上提出了独立型、半独立型以及包含型等三种外部空间结构,文章以西安创业服务中心为例进行研究,结论是:孵化器的成功在于宏观空间区位定位的准确,更在于微观区域创新环境的培育。同时从地理学的角度研究了企业孵化器,为其实现可持续发展、加速技术的商业化、产业化、国际化并推动区域经济的发展,提供建议。 相似文献

A series of pottery samples excavated from the Xigongqiao site in Tengzhou city of Shandong province was determined using inductively coupled plasma atomic emission spectrometry. Together with excavation data and archaeological analysis, the potential for provenance and technology of unearthed ancient pottery was studied by using multivariate statistical analysis and X-ray powder diffraction pattern (XRD) analysis. In order to characterize and classify these earthenware samples, the major and minor/trace element concentrations were studied with both cluster analysis and principal component analysis. The results showed that there were three different groups in cluster analysis dendrogram in good correlation with their colors. This indicated that the potteries were made from clays of different composition. These results were in agreement with the results of principal component analysis. XRD analysis further assessed the validity of multivariate statistical analysis. 相似文献

In this commentary we reflect on the potential and power of geographical analysis, as a set of methods, theoretical approaches, and perspectives, to increase our understanding of how space and place matter for all. We emphasize key aspects of the field, including accessibility, urban change, and spatial interaction and behavior, providing a high-level research agenda that indicates a variety of gaps and routes for future research that will not only lead to more equitable and aware solutions to local and global challenges, but also innovative and novel research methods, concepts, and data. We close with a set of representation and inclusion challenges to our discipline, researchers, and publication outlets. 相似文献
