自贡以盛产井盐闻名退迩,被誉为"千年盐都"。至今,在自贡民间还流传着"自流井盐井多如麻筛"的说法。正是凭借这数以万计的盐井,才使地下丰富的盐卤、天然气资源被不断地开发出来,促进了盐业生产的发展,带动了百业的兴旺和都市的繁荣。作为创造自贡辉煌历史的遗迹,一些古盐井仍然保存了下来。其中、最负盛名的是燊海井、东源井和吉成井。 相似文献

“盐都自流井,盛名传久远”。自贡盐业,历史悠久。从东汉章帝时期(76-88年)起,我们祖先就在这里开始了盐业生产,迄今已有近两千年的历史。自贡地区的盐业在晋代初具规模,唐宋闻名全川。明、清日趋兴盛,迄清咸同年间,独执川盐业之牛耳,一跃为井盐生产中心,盐产量占全川一半以上,除满足四川需要外,还远销滇、黔、湘、鄂等省,从而赢得“盐都”的称谓,饮誉中外。 相似文献

日军对自贡井盐基地的轰炸与中国的防御徐勇日军对中国西南井矿盐生产基地的大规模空中攻击,即通称的“盐遮断”轰炸行动,是日军统帅部所推出的具有战略意义的专项轰炸,其企图是摧毁中国内地的产盐基地并切断盐的运输通道。它构成了日军侵华作战史上的特殊一页,然而学... 相似文献

事件春节前的那场雨雪冰冻天气,瘫痪了半个中国,很多省市受灾严重,不少工厂企业限电停工、居民家庭限时供电,四川自贡和受到此次雪灾影响的很多地区一样,面临严重的电力紧缺。而与此同时,第十四届自贡国际恐龙灯会正在以前所未有的规模闪亮着。据相关媒体报道,本届灯会以"奥运圣火点亮百年灯城"为主题,一直开放到奥运火炬经过自贡,历时达150天,是此前灯会开放时间的5倍。 相似文献

综观半个多世纪以来的中国盐文化研究,其主阵地在四川、陕西、山西一带,关于井盐、池盐的研究也已趋于成熟。在中国盐业学会及中国盐文化研究中心的鼓励和倡导下,近年来山东、浙江、广州、云南等地相关盐文化的研究也在蓬勃开展。 相似文献

The present boundaries of Moscow's suburban zone are tested by delineating a so-called zone of active influence of Moscow city based on demographic structure and the significance of commuting to work in the city. The most favorable age-sex structure, with a high percentage of population in the working age groups and a relatively high percentage of children, is found in a zone within 50 to 60 kilometers from the city limits. This zone generates a daily flow of more than 500,000 commuters to places of employment in Moscow, 90 percent of whom spend less than 110 to 120 minutes traveling each way. These commuters represent about 2 percent of the total working-age population in the suburban zone. On the basis of the demographic structure and commuting linkages, Moscow's zone of active influence is therefore defined as the zone within which 90 percent of the commuters reside, or within 52 kilometers of the city limits. This conforms roughly to the present definition of the suburban zone. 相似文献

近年来,居民时空间行为的社会分异已成为学者们广泛关注的话题。然而,已有关于居民时空间行为的社会分异研究中,缺少对于居民活动情境的社会分异的研究。因此,本研究基于时间地理学中对人类活动的情境嵌入性与情境的不同维度的相关理论,以北京清河街道为例,分析不同住房来源居民在日常情境、地理情境和社会情境下的时空间行为的社会分异,尝试从多个情境维度拓展对时空间行为社会分异的理解。研究发现,市场性住房居民“朝九晚五”的活动特征明显,活动同伴选择外向性突出;单位性住房居民职住相对接近,在社区空间内分配时间最长且活动目的多样;安置性住房居民活动较为分散,地理情境与社会情境都呈现出“家庭内向性”特征;保障性住房居民非工作活动的“滞后性”明显,对社区空间的时间分配总体较低。除住房来源因素与个人社会经济因素外,建成环境因素对于居民对社区空间的使用有显著影响。 相似文献

网络搜索引擎是旅游者获取旅游信息的最重要入口,百度指数通过反映关键词被搜索的次数表征旅游者的网络关注度。文章以三清山为例,首先利用协整理论及格兰杰因果检验分析了PC端和移动端百度指数与实际游客量之间的关系,进一步建立日游客量ARMA模型和分别加入PC 端和移动端百度指数的VAR模型,对游客量预测结果及预测能力进行比较分析,以期通过不同客户端、不同搜索关键词来填补游客量预测过程中旅游网络数据提取的单一性,得到更好的预测效果。发现移动端比PC端百度指数模型具有更好的预测效果,移动端比PC端百度指数对实际游客量的变动具有更好的解释能力。 相似文献

Differences in industrial development of the Soviet union republics are found to persist, and the basic factors are analyzed. The presence of a skilled labor force is an important factor in insuring a high level of industrial output per capita and a high rate of return on capital. However, the distribution of labor-intensive industries does not always conform to the availability of labor resources. Such industries have reached a high level in the Baltic republics, where the reproduction rate is low and additional labor must be brought in from the outside, and they have not been fostered in Central Asia, where the rate of natural increase is high. The emphasis on resource-based industries that is characteristic of some republics (oil and gas in Azerbaydzhan and Turkmenia, nonferrous metals in Kazakhstan, etc.) is usually associated with a high level of fixed assets (capital intensity) and a low rate of return as well as low levels of industrial output per capita. 相似文献

Fifty-one waster sherds of Terra Sigillata (~20-0 b.c. ) from Arezzo, Italy and Lyons, France have been chemically analysed for twenty-eight elements by neutron activation and seven by X-ray fluorescence. Most of the elemental abundances were measured with high precision and cross-comparisons of the two techniques of measurement (and sample preparation) give added insight as to their relative precision, the calibration differences and the extent to which volatile materials such as carbonate or water influence the results. The sherds from Arezzo formed a homogeneous and distinctive chemical group while all but two of those from Lyons were classified into three such groups. Two of the Lyons groups (MML A and MML B) were from Montée de La Muette and one was from Loyasse. Four additional sherds from houses excavated in Strasbourg and one from Lyons, all of which bore the signature of the famous Anetine pottery-making firm of Ateius, were also analyzed by the same techniques. These signed sherds all had the same composition pattern and it closely matched one of those from Montée de La Muette (MML A) in Lyons. It is therefore suggested that these five sherds bearing the Ateius signature were made in the general vicinity of Lyons and were part of the output of an as yet unknown Gallic branch of the firm of Ateius. 相似文献

伴随全球化和城市化的快速推进,城市街巷空间的原生态环境和文化生活气息开始退变,城市记忆逐渐缺失,趋同化和均质化的城市危机显现。为此,选取南京夫子庙街区作为典型个案,采用认知地图、口述访谈和GIS空间统计方法,实证研究城市街巷空间居民的集体记忆,发现居民对夫子庙街巷空间的集体记忆呈现"光环区"→"亚光环区"→"缓冲区"→"盲点区"依次递减的特征和规律,"平民化"的城市设计理念缺失成为重要诱因。街巷空间作为城市公共空间的重要组成部分,具有特定的历史内涵与场所精神,其担负的集体记忆保护功能,应该引起学界和社会各界的广泛关注。 相似文献
