摘要
拉萨和日喀则分别是西藏第一和第二大的城市,在西藏经济发展中具有重要地位。利用经济联系强度和区域影响断裂点两个分析工具对近年来拉萨、日喀则的经济数据进行分析可知,拉萨-日喀则两市之间的经济联系强度以平均每年20%左右的速率增加,而两市之间的断裂点出现在距拉萨191.27km～217.75km附近。因此,加快西藏自治区的城市化建设,应注重保持和加强拉萨-日喀则两市的经济联系强度,以及重点扶持断裂点附近县市经济发展。
In the Tibet Autonomous Region,Lhasa and Shigatse are the two core cities in the region＇ s development,and they play a leading role for the development of other counties and cities. From the perspective of research on urban agglomeration and urban geography,the two cities have a relationship of interactive contact and common development. Within the context of rapid urbanization in China,the interactive development between Lhasa and Shigatse has become an inevitable research focus for the socio-economic construction of Tibet.The intensity of economic contact is used to measure the degree of regional economic ties. On the one hand,it can reflect the city＇ s economic center ability to radiate out to the surrounding areas. On the other hand,it can also reflect the level of acceptance of the surrounding areas to the city ＇ s economic center ability to radiate out to them. According to the results of economic calculation,the intensity of economic contact between Lhasa and Shigatse from 2007 to 2011 steadily increased with an annual rate of about 20%. The continuous increase of the intensity of economic contact also meant that the influence of Lhasa and Shigatse on the surrounding cities is expanding.Moreover,comparative data show that due to restrictions on the population and level of economic development,there is still a big gap in Lhasa and Shigatse if compared with other urbanized areas in China. However,regarding the increasing speed of the intensity of contact with other core cities,Lhasa and Shigatse have achieved remarkable a-chievements.During the 1930＇ s,William J. Reilly proposed the Law of Retail Gravitation which was used by P. D. Converse in the field of urban management to differentiate the scope of influence of neighboring cities. In 1949,he put forward the concept of ＂Breaking Point＂ together with a relevant computational formula. The Breaking Point is normally determined by the scale of two cities and the distance between them. According to the calculation results from the relevant data and
