20世纪六七十年代进行的三线建设,虽已过去几十年了,但对它的评价依然存在颇多争议。对三线建设作出分析评价,确非易事,很大程度上归因于其特殊性。有鉴于此,有必要提出三线建设二重性这一命题,即它既是旨在应对战争危险的特殊政治行为,又是谋求改善生产力布局的一般经济行为。由于战争没有绝对确实性,只有相对确实性,因此政府的经济行为并不总是取决于经济学原则,还要考虑社会政治的要求。与此同时,评价三线建设得失时,还要面对其经济分析的特殊因素和难以避免的模糊性。总之,三线建设得失相比,得是长期起作用的因素,是国家战略利益所系;失是得的必要代价,从根本上说是外部敌对势力强加给中国人的,也是暂时的,终归会得到补偿。  相似文献

1941年太平洋战争爆发前后,日本在国际上更加孤立。在物资贫乏、战争迁延日久、军需储存消耗殆尽、兵源枯竭及劳动力缺乏的情形下,日军对华北的依赖性日益加大。在华北,丰富的资源和广大的人力散布在农村,而农村又掌握在中国抗日革命的势力手里,华北日军只控制着寥若晨星的点和线。华北日伪通过"村政建设"向敌后抗日军民展开农村争夺战。"村政建设"主要源于中国历史上统治者控制乡村的统治术,也仿效了日本和伪满洲国的"街村制",体现了日伪利用中国旧有制度,实行法西斯统治的狡诈性。其目的在于根绝共产党及八路军抗日活动的民众基础。随着日军无条件投降,华北日伪的"村政建设"彻底破产。  相似文献

This paper reviews new developments in the study of modern Chinese history since 1979, especially key questions in modern Chinese history, together with innovations in content, structure and research methods. These new developments reflect the broadening of academic exchanges with foreign countries, the initiation of reforms, the influence of the modernization process, and far-reaching innovations in the discipline of modern Chinese history studies since the reform and opening-up of China.  相似文献

The turbulent climate of the Great Plains made windbreaks necessary for the protection of settlers and their livestock and crops. At first individual farmers tried to plant their own shelterbelts but with little success. The US Forest Service, with the establishment of the Bessey tree nursery, in 1902, and the field planting of the Nebraska National Forest, developed the expertise to carry out farm forestry on the plains. In 1934 the Forest Service undertook the Prairie States Forestry Project, an eight‐year program to plant shelterbelts from Canada to Texas, in response to the Dust Bowl and the Great Depression. These shelterbelts were a technological solution to environmental and social problems. As they grew, successful shelterbelts developed forest characteristics and served as habitat for birds and wildlife. As systems that were both technical and ecological, shelterbelts embodied a confluence of culture and nature in the technology that farmers and foresters used to engineer a more suitable environment for American society on the Plains.  相似文献

Harvest experiments of wild crop relatives are essential for our understanding of the biology of wild plants embodied in the economy of ancient forager communities. Most of the previous experimental harvest reports spanned a single season and therefore are unable to address questions concerning long-term yield potential. Herein we report on six consecutive harvest seasons taking place at four sites in Israel that harbour wild pea populations: three typical Pisum fulvum sites and one typical Pisum elatius site. Three out of the four sites showed no indication of a decline in grain yield as a result of repeated harvest and the removal of a considerable portion of mature seeds. Site-specific factors seem to have a strong influence on the grain yield as no seasonal yield similarity was observed between adjacent and ecologically similar sites harbouring the same wild pea taxon. The erratic year-to-year wild pea yield we observed calls for a reassessment of the presumed role of grain legume species in Near Eastern hunter–gatherers' diet. Combined with published data on cultivation of wild pea, our results are inconsistent with models suggesting protracted domestication of Near Eastern grain legumes or with the preliminary attempts to apply Niche Construction Theory to the study of plant domestication in the Near East.  相似文献

From the late 1600s to the early 1800s, Irish migrants journeyed to Newfoundland to take advantage of opportunities in the lucrative Newfoundland cod fishery. Focusing on the eighteenth and nineteenth centuries, this essay explores constructions of Irish-Newfoundland womanhood as articulated by local British officials, the Catholic Church, and male-centred family history narratives. These discourses located women at the margins of early settlement experiences or rendered them invisible altogether. Yet Irish-Newfoundland women were able to negotiate their own subjectivities within this discursive terrain, finding spaces for identity construction in the disjuncture between rhetoric and lived experiences. Some resided more immediately under the hegemonic gaze and struggled to break free from dominant narratives. But most became essential workers in household fishing production outside the capital of St John's, and their vital contribution as shore crews gave them considerable power and authority both in their households and in the broader community. Performing demanding physical work on stages and flakes (elevated wooden structures) or in gardens and fields, carrying out various economic activities in their own right, they were hardly the unproductive, unruly bodies of British official discourse or the passive flowers of civilisation narrated from Catholic pulpits. And far from being absent from the migration story, they were central players in community formation and the economic life of the island. In this historical context, proximity to/distance from hegemonic knowledge production created variations in identity construction within a group often represented in the literature as homogeneous and powerless.  相似文献

Fragments of Roman sewn‐plank boats have been found, during rescue excavations, in the Canale Anfora, an artificial channel used by Roman ships to enter the Roman city of Aquileia. Remains were found in both 1988 and 2005 at the same site. Elements of what were probably two boats are analysed and compared to other finds of Roman sewn boats found along the coast of the Veneto and Friuli Venezia Giulia regions. They are evidence of the use of this technique, instead of the more widespread mortise‐and‐tenon system, in the quite limited area of the Northern Adriatic. These boats were used both for inland and for maritime navigation.  相似文献

The shallow subsurface in historic cities often contains extensive archaeological remains, also known as cultural deposits. Preservation conditions for naturally degradable archaeological remains are strongly dependent on the presence or absence of groundwater. One of the main goals at such heritage sites is to establish a stable hydrological environment. Green infrastructural solutions such as Sustainable Urban Drainage Systems (SUDS) can support preservation of cultural deposits. Several cases show that implementation of SUDS can be cost effective at preservation of cultural deposits. These include Motte of Montferland, City mound of Vlaardingen, Weiwerd in Delfzijl, and the Leidse Rijn area. In all cases, the amount of underground infrastructure is minimised to prevent damaging cultural layers. SUDS have been implemented to preserve cultural heritage. The first monitoring results and evaluation of the processes give valuable lessons learned, transnational knowledge exchange is an important element to bring the experiences across boundaries.  相似文献
