陕北地区城市化驱动力研究

随着陕北地区能源资源的大规模开发与利用,陕北地区城市化战略取得了一定成绩,城市化水平大幅提高。本文基于对于城市化驱动力理论与实例的分析与总结,首先指出了陕北地区城市化发展中的问题,指出城镇化发展速度快,中心城镇辐射带动作用小,城镇密度小,城市基础设施滞后、生态环境退化等问题;其次提出了陕北地区城市化的驱动力主要分为动力机制与约束力机制两个方面。动力机制有经济发展、城乡人口迁移、产业结构调整、产业带动、大型项目建设、基础设施建设等;约束力主要表现在制度约束、生态环境约束及水资源约束等三方面。     

THE DECLINE OF CALIFORNIA'S NORTH COAST REDWOOD REGION

The Redwood Timber Region of Northern California has experienced a gradual decline in its natural resource base combined with intensified struggles over preservation and conservation. This region is used as a case study for examining the historic pattern of resource decline, the ambiguous roles of environmentalist pressure, the failure of public regulation, and a range of regional responses to economic decline. In this case, more intense forest management techniques (herbicides, fertilizer, thinning), more public investment in timber regeneration programs, and the emergence of an underground economy in marijuana growing are core elements of the response to resource decline. Theoretical, political, and environmental problems with these approaches are examined.     

TRAVELOGUE ON THE UNINHABITED LAND OF NORTH TIBET

<正>Setting foot on the eternally snow-covered Qinghai-Tibet national road and heading to the"roof of the world",my gaze was unavoidably fixed on the vast but harsh conditions in the north-west of the Tibetan plateau.This is the"Changtang uninhabited land"to which people so often refer. It has been about 20 years since I last encountered the"uninhabited land"of North Tibet.Surprisingly,however,today I find this mysterious land has undergone an earthshaking change.     

历史时期新疆北部城镇的形成与发展

历史时期新疆北部是草原游牧民族与汉族相互活动的区域,其城镇的形成与发展具有一定的草原文化景观特色。本文分析了新疆北部地区城镇的历史演变过程,提出其城镇萌芽于汉代前后,完善于清代后期,城镇的中心有一个从吉木萨尔-伊犁-乌鲁木齐的演变过程,并论述了新疆北部城镇形成与发展的特征和城镇发展的影响因素,得出研究历史城镇的发展对今天城镇建设与规划有一定的借鉴作用。     

LOCATIONAL FACTORS OF MACHINE MANUFACTURING IN THE SOVIET NORTH

Arguments are marshaled against the location of machine manufacturing in the North. The location of suppliers and the location of the market are viewed as negligible factors because machinery plants generally are supplied from a large number of sources and serve a highly dispersed market. The crucial element is said to be the issue of labor resources, particularly skilled labor, and the associated infrastructure that would be needed in the North. It is also pointed out that machine manufacturing is traditionally most cost-effective in large urban centers and in older industrial areas where it benefits from the so-called agglomerative effect of locational factors. It is recommended that metal-fabricating activities in the North be restricted to essential equipment repairs and overhauls and occasional manufacture of nonstandard equipment, with greater use of centralized supplies of spare parts.

关于建设我国北方集装箱枢纽港问题的思考

集装箱运输是世界交通运输发展的趋势,在这一进程中,集装箱枢纽港与支线港的形成与分化日益明显,它是集装箱运输规模效益发展的必然结果。随着我国集装箱运量的增加,合量布局我国集装箱枢纽港和支线港的问题日益突出,目前,香港和上海作为我国南方和中部集装箱枢纽港的地位已确立,而北方形成了大连、青岛、天津三足鼎立格局,合理布局北方集装箱枢纽港是我国北方各省区社会经济发展的客观要求。文章深入分析了北方主要集装箱港口的现状和潜力,并提出了我国北方集装箱枢纽港未来的发展战略。     

星辰大海环北中国追逐星空之旅

人们仰望星空感怀、揣测或想象,但极少追随星光而行走.星空有着让人痴迷的魅力,纵然是沧海桑田,星辰之美也未有丝毫瑕疵,神秘亘古,光华万千.能与星空结缘,无论谁的人生注定从此无感.只是,我们从星空汲取了如此多感动,又愿意为此付出多少代价?     

星辰大海环北中国追逐星空之旅(续)

追星·续Ⅰ 把车辙留在云之彼端的帕米尔高原 我们一行过喀什而不入,直接朝西边的帕米尔高原前进.这个一直让我魂萦梦绕的云之彼端,远远望去,高原群峰已耸立在天边.帕米尔高原,地处中亚东南部、中国的西端,横跨塔吉克斯坦、中国和阿富汗,是亚洲多个主要山脉的汇集处,古丝绸之路在此经过.中国古代称其为“不周山”,支撑着天地.“昔共工与祝融争为帝,怒而触不周之山,天柱折,地维绝.天倾西北,故日月星辰移焉;地不满东南,故水潦尘埃归焉”,而后女蜗娘娘采七色石补天.     

PROVENANCE OF PUMICES IN THE NORTH COAST OF CYPRUS

With the aim of establishing the provenance of pumices along the North Coast of Cyprus, from Morphou to Kormakiti, chemical analysis, refractive indices determinations and mineralogical examination have been performed. On the basis of the experimental data the pumices can be distinguished into two groups. For the first one a provenance from Santorini can be established, for the second Yali, Kos and Milos can be taken into consideration as source localities.
