我国经济行业分类对编制旅游卫星账户(TSA)的影响研究 总被引:5,自引:0,他引:5
旅游卫星账户(TSA)的特点是,以遵守SNA93的基本概念与核算原则为前提,采用与主体账户完全相同的生产范围和产品分类,从需求和供给两方面全面准确计量旅游活动对整体经济的影响。因此,国家经济行业分类制约着编制TSA的详细程度,从而影响TSA计量结果的准确性。本研究通过对我国TSA实践过程中出现的问题及原因进行分析,对我国原有的和新版的经济行业分类体系进行比较,提出上述观点,旨在于促进我国经济活动分类的不断细化,为构建TSA奠定良好基础。 相似文献

The late Mousterian of Acheulian tradition (MTA) site of Pech-de-l'Azé 1 shows a very particular stratigraphic sequence characterized by numerous elements not usually found in Mousterian contexts such as avifauna exploitation and the use of hundreds of mineral pigments. Recent zooarchaeological and skeletochronological analyses provide new insights into the evolution of subsistence behaviors and settlement patterns of the Neanderthals that inhabited the shelter. Due to changes in hunting season, Neanderthals adapted their hunting strategies, exploiting various red deer populations which presented very different behavior. The evolution in the seasonal occupation of the shelter may have been the results of major modifications of its (series of roof collapsed) which induced a shrank in inhabitable space., which forced the Mousterians to adjust the way they used the cavity to its characteristics in order to optimize its exploitation. The conclusions underline the excellent adaptability of the Neanderthals to their physical environment. 相似文献

The subsistence strategies of the Lapita populations (3100–2800 BP), the first colonisers of the pristine environments of the islands of Eastern Melanesia and Western Polynesia, have been a matter of ongoing debate for decades. Opinions have ranged between the two extremes of Lapita colonisers being either characterised as highly mobile foragers to fully horticultural communities. To further address the question, this paper presents stable carbon and nitrogen isotopic data obtained from analyses of human and animal collagen samples from the site of Teouma (Efate, Vanuatu) dated to between c. 3000–2500 BP. The isotopic signatures obtained from 28 samples (23 human and 5 animal), interpreted in combination with isotopic information from several coastal and insular environments, suggest a diet primarily made up of terrestrially derived animal protein with lesser contributions from vegetable produce and inshore marine species. Comparisons linking the isotopic data gleaned from the Teouma individuals and Lapita subsistence patterns reconstructed through archaeozoological and archaeobotanical remains support the hypothesis of a mixed economy, that included terrestrial foraging, inshore marine exploitation and a low level of food production for at least some of the earliest Lapita colonists in Vanuatu. 相似文献

在河口三角洲地区,河流是与人类活动关系最为密切的自然元素。本研究选取位于珠江三角洲核心区的广州市五眼桥涌地区为典型案例,通过实地调查、标图和深度访谈,结合相关的统计资料和历史文献,解析了快速城市化背景下珠江三角洲河涌环境的演化过程及动力机制,并分析了人-河关系的演进。研究发现案例地的河涌环境在地貌形态和水环境方面都发生了剧烈变化;城市河涌环境演化的主要动力来自于社会生产层面和个人生活层面的人类活动变迁。案例地人与河涌关系的演进经历了亲密和谐、对立隔离、重塑改善三个阶段。 相似文献

黑水国汉代墓葬出土的农具、动物骨骼、农作物遗存和人骨为人们了解河西走廊张掖地区汉晋时期生业经济和农业发展等问题提供了重要证据。通过动物骨骼、农作物遗存鉴定结果和人骨碳氮同位素检测结果,可以揭示汉晋时期黑水国人群的食物结构和生业模式特点。墓葬出土的农作物有粟、黍、稻,随葬动物有鸡、猪、绵羊、黄牛、狗、马,人骨骨胶原碳稳定同位素主要呈现C3和C4混合信号,部分呈现C3信号和C4信号,氮稳定同位素值相较牛羊等家养食草动物较高。综合研究说明汉晋时期河西走廊形成麦类、粟黍和豆类的混合农业模式,所以黑水国汉代先民摄取的粮食作物来源呈多样化。同时,河西走廊畜牧业发达,使当时人群摄取了大量的肉食资源,导致蛋白质摄入量较高。 相似文献

This article studies the relationship between local society and social change in rural north China from the late Qing dynasty to the People’s Republic of China period through the activity of “Zhuo huanggui” (literally, “Catching the Yellow Ghost”). “Catching the Yellow Ghost” is a ritual activity in Guyi village, Wu’an county, Hebei province. According to villagers there, “Catching the Yellow Ghost” has been celebrated since the late Qing dynasty. However, due to political pressures in the 1950s, it was not until the 1980s that “Catching the Yellow Ghost” began to be revitalized. Since that time, “Catching the Yellow Ghost” has gained rapid popularity and fame in north China. Through the lens of the “Catching the Yellow Ghost” ritual, this article explores social transformation in China from the late 19th to the early 21st century. By analyzing the continuity and discontinuity of “Catching the Yellow Ghost,” this article offers a new understanding of the relationship between local society and social change in rural north China. 相似文献

近年来,内蒙古巴林左旗辽上京城址开展了系统的植物考古工作,为了解辽金为代表的少数民族政权统治时期的生业和消费模式提供了重要的线索。在城址金元时期遗存中,发现了极其丰富的植物遗存,包括十一种农作物,五十余种非农作物遗存。尤其是在城址中“一号街”为代表的古代生活区,植物遗存的发现尤为突出。这些农作物组合结构显示出以粟、黍为主的多品种旱作农业种植体系;非农作物遗存中则包含了大量可能的家畜饲草种子,为畜牧发展的程度和规模提供了重要线索;西瓜、亚麻等外来作物出现在了上京城的一般性民居,而大麻、葡萄属种子的特殊保存背景也为了解其利用方式提供了证据。通过与周边辽金时期已发表植物考古研究的比较,可以发现遗址等级、族群等因素对本地生业模式、农业种植结构选择上的影响。 相似文献

漓江沙洲的形成,是自然环境和人类活动交互影响的结果。明清以降,外来人口不断进入漓江上游地区从事农业垦殖活动。垦殖活动在改造了上游山区自然环境的同时,其产生的泥沙在雨水作用下进入漓江,促进了桂林段漓江沙洲的发育,并改变了桂林段漓江河床的面貌。岸上居民也开始由岸上洲,这是漓江流域人地关系的重要变化。 相似文献
