EFFECTS OF CLIMATIC VARIATIONS ON WATER WITHDRAWALS IN METROPOLITAN TORONTO

In this pilot study of water withdrawals in Metropolitan Toronto, a quantitative assessment of the impact of weather and climate variations on t 980-3 water use is presented. Variations in daily water use were positively correlated with temperature, potential evapotranspiration, and climatic water deficit, and negatively correlated with summer precipitation. This kind of information will be useful to policy makers, who will have to plan for a future climate that may be different from today's if the 'greenhouse effect' does indeed create a warmer, drier environment in the Great Lakes region.
On décrit une étude-pilote sur les retraits d'eau dans le grand Toronto. Elle vise à quantifier l'effet des variations météorologiques et climatiques sur l'utilisation d'eau en 1980-3. l'utilisation d'eau est directement proportionnelle à la température, à l'évapotranspiration éventuelle et au déficit en eau du climat, mais inversement proportionnelle aux précipitations d'été. Ce genre d'information sera utile aux autorités compétentes qui devront établir des plans en fonction d'un climat qui sera peut-être différent de celui d'aujourd'hui, si l'éffet de serre' engendre effectivement un milieu plus chaud et plus sec dans la région des Grands Lacs.     

THE PHYSICAL FACTOR IN THE SYSTEM OF CONDITIONS DETERMINING THE LOCATION OF INDUSTRIAL PRODUCTION IN THE USSR

The generally accepted view that material-intensive industries tend to gravitate toward raw-material sources is analyzed in the case of the USSR. Primary processing is found to gravitate toward raw-material sources mainly in underdeveloped parts of the country. In the developed zone (European USSR, Urals, Transcaucasia), a significant spatial gap has developed between primary processing activities and raw-material sources as the original local resources become depleted and the industry must draw increasingly on long-haul raw materials. Several industrial groups are distinguished in terms of the pull of resource sites. In view of the current trend toward greater concentration of production (for cost-benefit reasons) and the growing volumes of production per establishment, primary processing establishments are usually dependent on more than one resource site, and this also tends to increase the length of haul. At the same time, the distribution of fuels, energy and water resources is assuming greater significance and tends to pull such industries as iron and steel, nonferrous metals, pulp and paper as well as petroleum refining toward the eastern areas of the USSR. The controversy over the location of a new integrated iron and steel plant based on ore from the Kursk Magnetic Anomaly is recalled.     

基于因子分析的长春市犯罪分区研究

选取了2008年长春市主城区各警区(共74个)内的8种常见犯罪,并对其进行了基于主成分的因子分析。基于日常活动理论(routine activities theory)的理论框架,通过分析不同主因子得分的空间分异状况,并结合各地段人口集聚、社会经济、土地利用等方面的特征,探究各主因子的内涵、关联和空间格局的成因。结果表明长春市2008年8种常见犯罪可以归为3个主因子上。其中主因子1在伤害、诈骗和偶发性暴力犯罪上载荷最大,可以归结为经济活动主导(或就业主导型)型因子;主因子2载荷最大的犯罪包括抢劫、抢夺和扒窃,可以归结为商贸、餐饮、文娱活动主导型因子;主因子3载荷最大的犯罪包括入室盗窃和机动车盗窃,可以归结为居住活动主导型因子。     

基于因子分析的民族文化旅游产品真实性评价体系研究

目前国内外关于民族文化旅游产品真实性的研究非常薄弱。民族文化评价指标体系是由建筑及遗迹、服饰、饮食、工具及工艺品、语言及口承文化、节庆和习俗等6个方面共28个指标构成的系统。采用专家打分法采集相关数据,运用SPSS法对数据进行因子分析,计算因子载荷矩阵,从而构建了民族文化旅游产品真实性评价模型。运用模型,可以识别民族文化旅游产品真实性的主要影响因素及其影响程度,有效解决民族文化保护与开发之间的矛盾。     

基于验证性因素分析的旅游地地方依恋结构解析——以广州白云山为例

本文以广州白云山作为研究对象,在前期采用"游客使用图片"(VEP)方法的基础上,构建了旅游地的地方依恋结构模型。基于1947份问卷数据,运用结构方程模型的验证性因素分析方法对旅游地地方依恋的结构进行检验,分析结果显示了旅游地的地方依恋结构与数据拟合良好,修正后的旅游地的地方依恋结构更加清晰、信度与效度更加理想,同时验证了地方依恋的二阶因子结构,即旅游地地方依恋的结构由环境景观维度、休闲维度、人际社交维度和设施服务维度4个维度及16个具体特质指标构成。     

SOME THEORETICAL PROBLEMS IN GEOMORPHOLOGY

The author takes issue with a number of theoretical issues discussed in a recent book by Yu. G. Simonov, fellow Moscow University geomorphologist. A definition of the central problem in geomorphology as encompassing the interaction between endogenic and exogenic forces is said to leave out the role played by the landforms themselves in exerting an impact on those outside agents and, through them, on surface relief itself. Spiridonov favors a systems approach to geomorphology, but questions the suitability of the term “morphosystem” proposed by Simonov as a substitute for morphosculpture, signifying the impact of exogenic processes on landforms. Surface relief should be investigated as an open system, although some simplified situations, such as an enclosed drainage system, might be studied in terms of closed systems, making possible the use of mathematical techniques. The importance of the application of formal logic in geomorphic classification is stressed, and the use of synthetic parameters is favored for purposes of landform classification.     

产业要素配置结构对生产率的影响研究——以杨凌示范区为例

本文基于要素生产率变动的视角,以杨凌示范区为例,在分析产业要素配置结构对生产率的作用路径基础上,通过估算资本存量,分析产业要素配置结构的构成,并利用偏离-份额法研究产业要素配置结构对生产率的影响作用。研究结果表明,杨凌示范区存在产业要素错配,第二产业成为杨凌示范区经济增长的核心部门,而第一产业的要素投入与发展农业现代化的目标不协调;劳动生产率的增长主要来自产业内部的增长效应,而非配置效应,其经济增长主要依赖要素投入带来的产业规模扩张;资本生产率的增长主要来源于产业内部的作用,在杨凌示范区发展初期,产业要素配置结构对资本要素生产率起到了阻碍作用,但这一情况正在逐渐改善。     

岭南文化对广东外省人群体影响之探讨

本文从文化地理学的角度,以文化问卷调查为基础,采用定量与定性分析相结合的方法,探讨了岭南文化对广东外省人群体的影响特征。笔者发现:岭南文化影响广东外省人群体的总体特征呈中间型,南方群体、男性群体比北方群体、女性群体易于接受岭南文化。并得出几点结论:在文化扩散的早期阶段,等势文化之间的影响排斥性较明显,表层文化相对于深层文化接受大于排斥,文化距离对深层文化的扩散起决定影响,经济条件对表层文化的传播起关键作用。     

论中国城墙的起源

中国的城墙起源于原始社会后期,即龙山文化时代。它是由壕沟演变而来的防御工程,并逐渐代替壕沟而成为城市防御的主要手段。
经过夏、商两代的发展,西周时代已普遍筑城,城和国已成为同义词。而且筑城技术也发展到一个新的高度,与今天的筑城方法十分相似。
城和市都兴起很早,二者之间也没有关系。由于西周时代城内设市,就出现了中国早期的城市。"城市"一词起源于战国,即设市之城邑谓之城市。     

PECULIARITIES IN THE FORMATION OF POPULATED PLACES ON THE SEABOARD OF THE USSR

A number of investigators have noted a movement of Soviet population toward the seacoasts, contrasting with the nation's traditional inland development. The pull of the coast has been linked to the increasing foreign trade of the USSR and to greater involvement in ocean affairs in general. The author analyzes the recent growth of maritime urban places in terms of the nation's major maritime regions: Azov-Black Sea, Baltic, Caspian, Pacific and Arctic, compares the rates of urban population growth and discusses some of the factors that account for differences in regional development.
