在明代,由于水患频发和长江主泓变动等原因,湖广武昌府城沿江江岸屡屡崩陷,当地政府遂启动江岸修筑工程。考诸史志,明代武昌府城的江岸修筑主要约有四次,分别是正统七年(1442)、成化三年(1467)、万历十七年(1589)和万历三十四年(1606)。最终修成的江岸,自武昌府城南门望山门外(今武昌解放路南端解放桥附近)起,向西折至江边,又沿江边中经黄鹤矶向下游延伸至坛角地区(今武昌和平大道武汉工人文化宫以西),长约5公里。这条堤岸确定了武昌城沿江江岸的基线,将武昌城的城市空间扩展到江边,并延续至今。  相似文献

水资源短缺一直制约着京津唐地区经济和社会的发展。20世纪70年代,因缺水引发的经济、社会问题逐渐凸显,促使中央和地方政府开始考虑实施跨流域调水工程。引滦工程作为北方最大的跨流域调水工程,其决策经历了曲折的过程。1958年,北京和唐山曾分别提出引滦河水的设想,唐山还实施了引滦入还和引还入陡工程。1972年,海河流域大旱促使中央做出加快实施引滦工程的决定,但由于地质情况复杂等原因,引滦工程设计方案被反复修改。1981年,天津提出了单独引滦济津路线并得到了中央的支持。引滦工程对缓解京津唐用水紧张发挥了重要作用,天津是引滦工程受益最大的地区。  相似文献

Recent Paleolithic work along the middle Enisei River of central Siberia has revealed a long history of occupation that almost certainly begins in the Middle Pleistocene. Although the evidence for the Lower Paleolithic is somewhat tentative, there is good reason to believe that hunter-gatherers had periodically occupied the middle Enisei before the last interglacial. The steppe environment of the region during the Upper Pleistocene was relatively bountiful; more than 200 Upper Paleolithic sites, both before and after the Last Glacial Maximum, have been located. The region appears to have been abandoned during the Last Glacial Maximum. Most of Soviet and Russian archaeological work has been guided by a cultural–historical orientation, but recently there has been increased interest in developing adaptationist and ecological research strategies. The middle Enisei and the wider central Siberian region are key to understanding early adaptations to the north and the dimensions of Paleolithic population movements.  相似文献

An error dating from 1885 in mapping the upper Strickland River, Papua New Guinea, was reinforced and extended by government officer Charles Karius in 1929 when reporting results from a lengthy exploratory patrol. Detailed maps produced by the US Army and the Royal Australian Survey Corps in, respectively, 1942 and 1966 perpetuated these errors. It was not until 1979, with release of a series of 1:100,000 topographic maps, that long-standing errors were finally put to rest. Throughout these years, the contributions of well-informed people tended to be ignored in favour of the opinions of those whose status implied authority.  相似文献

义和团运动时期的北方战事,给包括租界在内的上海及江南民众日常经济生活带来巨大恐慌。身处纷乱的惊惧不安和经济萧条的切实威胁,社会各界普遍企望北方战事早日平息,不致蔓延到南方,这种社会心理氛围,是"东南互保"得以产生和推行的重要原因。  相似文献

2013年淮安市博物馆发掘淮安王庄村汉墓群,共清理汉墓97座。墓葬形制多样,排列有序,共同位于一大型土墩之下,与淮安地区传统族葬墓有明显的区别。墓葬随葬器物丰富多样,器物组合时代特征明确。从出土器物和墓葬形制及排列情况分析,墓葬时代在西汉早期至东汉时期,墓葬之间在年代上有明显的承继关系,是一处大型汉代土墩墓。该墓地的发掘为研究淮安乃至苏北地区汉代墓葬特别是汉代土墩墓类型提供了极其重要的新材料。  相似文献

In recent decades in Europe, municipalities have promoted many poorly qualified and widespread industrial parks. These policies have caused various problems such as oversupply of industrial land, obsolescence and high vacancy rates. The future of these sites is uncertain and has become a key issue in planning. Nowadays, policies are focused on upgrading these sites and on implementing regional coordinated practices. This paper describes a methodological approach to identifying a subregional network of industrial parks in the Ave valley, Portugal. The network is based on the parks’ attractiveness and has the purpose of supporting planning policies in terms of upgrading and providing new sites. The approach was based on a multi-criteria analysis whereby the parks were ranked according to their attractiveness considering their coverage in terms of infrastructures, services and accessibility. Results show that the majority of the existing and planned parks, even if upgraded, will not be very attractive and will be limited to a municipal scale due to structural problems related to their location and poor coverage. Moreover, the paper also discusses the challenges in implementing this planning approach at a subregional level. Despite the specificities of the case study, this methodology could be adopted in similar studies.  相似文献

Since 2009, Innu members of the community of Ekuanitshit have faced a major hydroelectric project on the Romaine River, an integral part of the Nitassinan, their ancestral territory. In this paper, we study the project's impacts on the material and ideational relationship the Innu have with the river. We explore the idea that the project transforms the traditional relationship to territory into a more pragmatic one, marked by economic and political interests. Our analysis reveals that the Innu's territorialities, though partly transformed by increased contact—and sometimes conflict—with hegemonic non‐indigenous society, remain anchored in a strong cultural heritage and a deep identification with territory. We argue that these seemingly differentiated conceptualizations, of traditions on the one hand and development on the other, are not incompatible. These conceptualizations comprise dynamic cultural, social, and political territorialities which are thus internal and external, ancestral and contemporary.  相似文献

光绪十三年(1887年)黄河在郑州决口,是铜瓦厢改道后最大的一次黄河水灾。对于此次水灾期间的赈灾事务,学界以往甚少注意。实际上,此时以江南绅商为主体的民间力量自发组织动员的义赈活动,不仅承担了此次赈务中的很大一部分工作,而且是整个晚清义赈机制发展到一个新阶段的标志,其实践逻辑甚至还可以帮助我们推进此前关于地方史研究取向中国家与社会的关系的反思。  相似文献
