INFRASTRUCTURE CONSTRUCTION IN THE LONGHAI-LANXIN ECONOMIC BELT OF CHINA ALONG NEW ASIAN-EUROPEAN CONTINENTAL BRIDGE

Infrastructure construction is the precondition for promoting regionaleconomy and intemational cooperation. In this sense, the Newlyopened AsianEuropean Continental Land Bridge (NOAECLB) will provide a great opportunityfor all the ropons along its sides to speed up their econondc growth. This paperfocuses on evaluatin the Changing pattem of economic growth in the repions alongNOAECLB within China's boundary in general and discusses the problems, majortasks and relative polides for infastructllre construction in this area in particLilar.

WATER ENVIRONMENT AND SUSTAINABLE DEVELOPMENT ALONG THE BELT OF XINJIANG SECTION OF THE NEW EURASIAN CONTINENTAL BRIDGE

The opening of the new Eusasian Continental Bridge not only brings about great opportunities for development of Xinjjang, but the plays a major role in reducing the gap between the western and eastern parts of China. In general, Xinjiang section of the new Eusasian Continental Bridge goes ahead along the oasis belt of northern slope of the Tianshan Mountains with advanced economy and concentrated populattion. The main factor to determine the fate of oasis is water. There are relativdy more rivers in Xinjiang section Of the Eurasia Continental Bridge. But as far as the region is concerned, if we take Ururmqi as the boundary, river runoff of the western section accounts for 90%,the eastern section just occupies 10%, so surface runoff is highly concentrated in the west. In this paper, river water envirotnment and ground water environment are evaluated emphatical . On the whole,the status of water environment of seven rivers being evaluated is gradually improved and ground water quality of main cities along the bridge is good. In the future, carrying out sustainable development strategy and doing well in compositive prevention and cure should be long-term guidelines so as to ensure the normal running of the new Eurasia Continental Bridge and economic development along the continental bridge.

THE EFFECT OF THE NEW EURASIAN CONTINENTAL BRIDGE ON THE EASTERN COASTAL AREAS OF CHINA

Lianyungang——Head on the New Eurasia Continental Bridge

Since the new Eurasia ContinentalBridge was formally opened in 1992,the East Bridge Tower-- Lianyungang-- has been attracting more and more attentionin the circles of transport and trade worldwide.In 1995, Lianyungang successfully organizedwhole line transport by rail for internationaltransit containers, and freight volume on theContinental Bridge is growing at an acceleratedspeed. At present, Lianyungang hasundertaken the task of transport for the totaltransit containers along the new EurasiaContinental Bridge. The countries and regionsthat make use of the Continental Bridge toconduct transport include the USA, SouthKorea, Japan, Kazakhstan and Hongkong.Between 1992 and 1995, a total of 8。

Eurasia Continental Bridge——An Important Link of the Coordinated Development between China's Eastern,Central and Western Regions

The new Eurasia Continental Bridgeruns from East China to Central andWest China, crossing 11 provincesand regions, namely Jiangsu, Shandong,Hubei, Anhui, Shaanxi, Gansu, Shanxi,Sichuan, Qinghai, Xinjiang and Ningxia.The total area is 3.6 million sq km and thepopulation is about 300 million, accountingfor a third and a quarter of the whole countryrespectively. The area is very rich in naturalresources, so it is called an "Economic goldbelt" and "Gold corridor". Aerial remote-control survey indicates that along thecontinental bridge from Lianyungang to theAla Mountains within China’s boundary,

THE POSITION AND ROLES OF PORTS AND RAILWAYS IN THE EURASIA LAND BRIDGE TRANSPORTATION IN NORTHEAST CHINA

This paper systematically analyzes and proves the favorable factors of utilizing the ports and the railways in Northeast China for the Asia-Europe land bridge transportation. It will be more beneficial to Dalian Port and HaDa (Harbin-Dalian) and Binzhou (Harbin-Manzhouli) railways in Northeast China to the Siberia railway in Russia than 1) to other ports and the corresponding railways in China, 2) to the Nakhodka Port in Russia and the corresponding railways and 3) to the Chongjin Port in North Korea and the corresponding railways. This paper also puts forward the reform measures to adopt the ports and the railways in the northeast region in China for the land bridge transportation and the problems in transportation policies and management systems.

Explicating the mechanisms of land cover change in the New Eurasian Continental Bridge Economic Corridor region in the 21st century

Land cover change has presented clear spatial differences in the New Eurasian Continental Bridge Economic Corridor(NECBEC)region in the 21 st century.A spatiotemporal dynamic probability model and a driving force analysis model of land cover change were developed to analyze explicitly the dynamics and driving forces of land cover change in the NECBEC region.The results show that the areas of grassland,cropland and built-up land increased by 114.57 million ha,8.41 million ha and 3.96 million ha,and the areas of woodland,other land,and water bodies and wetlands decreased by 74.09 million ha,6.26 million ha,and 46.59 million ha in the NECBEC region between 2001 and 2017,respectively.Woodland and other land were mainly transformed to grassland,and grassland was mainly transformed to woodland and cropland.Built-up land had the largest annual rate of increase and 50%of this originated from cropland.Moreover,since the Belt and Road Initiative(BRI)commenced in 2013,there has been a greater change in the dynamics of land cover change,and the gaps in the socio-economic development level have gradually decreased.The index of socio-economic development was the highest in western Europe,and the lowest in northern Central Asia.The impacts of socio-economic development on cropland and built-up land were greater than those for other land cover types.In general,in the context of rapid socio-economic development,the rate of land cover change in the NECBEC has clearly shown an accelerating trend since 2001,especially after the launch of the BRI in 2013.

Environmental hazards in Xinjiang Line of New Eurasian Continental Bridge

Xinjiang Line of New Eurasian Continental Bridge is the important lifeline project inwestern China. Various disasters, such as flood, strong wind, sandstorm, and roadbed disasters,have been seriously affecting the railway transportation. The field investigation and analysis on thedata collected since 1959 show that: serious floods often occurred when the rain intensity reached25 mm/h or 30 mm/d; the critical wind speed for turning over a train is between 35 m/s and 67 m/s,and such cases happened in draught places of mountain opening and trunk valley; the angle be-tween wind direction and railway is closely related to the thickness of accumulative sand along thelines; roadbed disasters taking the form of side-slope sliding, roadbed sinking and silt turning uptook place in spring when the temperature rapidly rose to 10-15℃ from zero and precipitationcame forth or when the thickness of snow cover on shade slope reached above 20 cm in winter;the disasters taking place in the 1990s were far stronger than those of the 1980s and the order ofhazard intensity along the Xinjiang Line is Urumqi＞Shihezi＞Kuitun＞Liuyuan＞Shanhan＞Hami.

艾比湖地区风沙危害趋势及对欧亚大陆桥的影响

艾比湖是新疆最大的尾闾盐湖,地质历史时期和人类活动时期处于不断干缩状态,所形成的干涸湖盆物质在阿拉山口大风驱动下对区域构成风沙危害。从物质来源和驱动风力两个方面分析了风沙危害的可能性;并在剖析扬尘爆发频率和风力条件变化趋势的基础上,得出近40年风沙危害加剧的主要由于沙尘策源地扩大的结论。重点分析了欧亚大陆桥艾湖段风沙危害现状及趋势,认为由于区域风力条件的稳定性,只有在与艾比湖地区生态环境恢复重建的基础上,进行全线的生物防护措施,改善下界面状况,才能取得可持续的防沙效益。

新亚欧大陆桥新疆段是我国西部重要生命线工程 ,横跨四大不同地貌单元 ,孕育了由暴雨山洪形成的水害、大风、沙害等为主要类型的环境地质灾害。重大水害事件形成于 2 5mm/h或≥ 30mm/d雨强过程中 ,集中出现在 7月份 ;大风刮翻列车的临界风速为 35m/s～ 6 7m/s之间 ,发生在山体豁口及呈“箱”型谷地的风口区 ;风沙流含沙量随高度遵循指数函数关系分布 ,在风向与线路夹角 >45°时 ,线路积沙厚度迅速增加。对各工务段辖属区段易损性分析表明 ,区段灾害活动强度依次为 :乌鲁木齐 >石河子 >奎屯 >柳园 >鄯善 >哈密。未来水害频次和强度将日趋增大 ,沙害范围及影响程度将日益加重。

充分利用大陆桥优化沿海能源供应

新亚欧大陆桥富聚了我国大部分能源资源，它不仅是全国能源生产的主要基地，也是我国洁净能试验生产带，还是国外能源的开发输送带；沿海是我国能源消费的集中地区，其经济发展与能源供给不足的矛盾日益突出。为此，本文提出了利用陆桥优化沿海能源结构的对策和建议：陆桥带与沿海地区充分利用各自所长，优势互补；建议国家及早开发利用中亚油气和西部油气东输问题的研究；及时进行江南尤其沿海地区地下油气管网的铺设研究；沿海地区用能要海陆兼顾，多能互补优化能源结构。
