黑河流域居民生活质量研究 总被引:1,自引:0,他引:1
以《Calvert-Henderson生活质量指标》一书为理论指导构建了生活质量评价指标体系,通过开展生活质量问卷调查及查找相关统计资料,运用主成分分析法确定指标的权重,研究了我国西北地区第二大内陆河流域-黑河流域城乡居民2004年的生活质量。具体的评价结果是:黑河流域城镇居民生活质量明显高于农村;黑河流域城市居民生活质量表现出中游高于上游和下游;黑河流域农村居民生活质量以乡镇为单位计算差异显著;黑河流域农村居民生活质量中游略好于上游、下游;影响黑河流域城乡居民生活质量的主要因素是收入、教育和住房。 相似文献

1998年10月~11月,郑州市文物考古研究所与巩义市文物保护管理所对巩义市白河瓷窑遗址进行了调查,现将调查情况介绍如下。 一、瓷窑遗址的分布与现状 白河村又名白冶河,可能因烧白瓷而得名,白冶河位于西泗河上游,沿河下行十五华里到洛河人黄河处,交通便利。白河水源于村南水地河的石泉。瓷窑遗址分布于沿河两岸,绵延十余里。(图一) 据历次调查情况看,白河上游的瓷窑遗址时代较早,在白河村南的柑子泥沟、赵家 一带,发现有南北朝时期的青瓷,因早年平整土地,现在沟已被填平,这次调查未见有此时期的遗物。隋代,瓷窑作… 相似文献

Temporary consolidation is widely used to protect delicate artefacts or other fragile relics in art conservation. Although cyclododecane is extensively accepted, the safety‐related issues have become an increasing concern and its short working time is always annoying. Inspired by its low melting point, polar structure, well‐established safety profile, easy local availability and low cost, we propose menthol as a new temporary consolidant on the new excavation site of Qin Shihuang's Terracotta Army. In this paper, we offer a preliminarily exploration of the kinetics of menthol sublimation on two different matrices, its residue after volatilization, its penetrability and distribution in simulated terracotta samples, as well as other important properties in the laboratory. The results obtained from these tests reveal that the sublimation of menthol can be a zero‐ or a first‐order process, depending on the porosity of the matrices, and its best operational temperature resides in the range of 60–80°C. Finally, two field cases at the archaeological site of Qin Shihuang's Terracotta Army are presented to show that menthol is a very effective temporary consolidant. 相似文献

基于Amos的环境地方性与游客地方感之间的关系机理分析——以西安大明宫国家考古遗址公园为例 总被引:1,自引:0,他引:1
本文以西安大明宫国家考古遗址公园为例,基于空间形态要素、公园景观要素、服务配套要素、地方性、地方感5个潜在变量,构建地方性与地方感之间的因果关系结构方程模型.通过预设观测变量因子设计量表,发放200份调查问卷,回收181份有效问卷,再运用SPSS建立有效分析数据库,并基于Amos7.0平台进行结构方程模型的验证性分析,从而探讨大明宫国家考古遗址公园空间环境营造的地方性特征与游客地方感之间的关系路径及运行机理. 相似文献

上海市民大型超市购物行为特征研究 总被引:9,自引:0,他引:9
以上海居民消费行为的问卷调查为基础,探讨零售业态变革下上海居民大型超市购物行为的总体特征以及时空间特征。上海居民选择大型超市购物的比率及频率较高,在大型超市购物的耗时相对较长,并且有集中于夜间的特点,购物出行方式上以步行和自行车为主,陪伴者以家人居多。通过不同类型商品购物行为空间的分析得出,大型超市对居民购物出行空间的影响显著。受大型超市空间分布和周边其他零售业设施发育程度的共同影响,居民购物活跃度的空间差异也较为显著。 相似文献

We describe a preliminary survey of a relatively unknown part of the eastern Himalayas: northwestern Sichuan. This survey revealed that three phases of occupation are represented across the landscape. Large settlements with dense remains characterize the landscape during the Neolithic (3400–2000 cal b.c.). Following a hiatus in occupation, stone-cist graves characterize the region during the Bronze Age (1450–800 cal b.c.). The lack of settlement remains from this period indicates that mobile pastoralism increased in importance. Finally, between a.d. 500 and 1500, dense scatters of ceramics over a wide altitudinal range correspond to a fragmentation in Tibetan history, when local warlords established themselves in the region. While some changes in occupation and subsistence practices are linked to climate change, others relate to changes in political power. We argue that further survey work is needed to expand our understanding of past land use and the development of pastoralist practices. 相似文献

This paper examines the case of the court-ordered excavations at Ayodhya to understand the process by which archaeological evidence as expert opinion was reconfigured into judicial evidence in a civil lawsuit. Being an exceptional site of enquiry where two institutions of the Indian state — the High Court of Allahabad and the Archaeological Survey of India — come together, the Ayodhya case allows us to complicate the uses and abuses of archaeology. An examination of the orders and documents related to the excavations and the judgment made by the Allahabad High Court shows the production of archaeological knowledge at Ayodhya as highly mediated. The paper argues that this process is determined by the notions shared by both the institutions about archaeology-as-science and about scientific/archaeological expertise, regulated at each stage through judicial interventions and informed by the role that the Archaeological Survey of India and the archaeology profession has played in the production of a nationalist past in India. The employment of archaeology as legal evidence in the Ayodhya case is contingent upon the masking of these mediating roles. 相似文献
