The Urban Functional Contact Evolution of Temporal and Spatial Pattern Analysis in Northeast Region
研究了2001-2011年东北城市功能联系的时空演变，发现信息、交通和资金流增长，空间格局从分散趋于集中，形成一廊四核四组团的结构。
Urban functional contact is a mechanism that urban system interact with the region. Researching the urban functional contact which has both theoretical and practical importance,can help to reshape the regional Spatial Patterns,promot the consolidation of near urban field and coordinate the development. Select related indexes of the northeast cities in 2001-2011,such as total of posts and telecommunications,transportation of passenger and cargo,fixed assets investment,actual amount of foreign capital,etc. Establish the index system of urban functional contact. Combining with spatial autocorrelation and correlation test of urban functional contact and GDP,from spatial and temporal perspective,analyze and discuss the evolution pattern and spatial correlation of the urban functional contact. The results show: 2001-2011,the fiow of information,traffic and fund is increasing,the composition structure and the spatial pattern also show complex change,each different grade cities and element flow display significant spatial differentitation characteristics.2001-2011,the urban functional contact in northeast region has experienced slow growth period,transition period and the period of rapid and sustained growth,and the Spatial distribution go through variation tendency,inferior concentration-random distribution-slow concentration. The spatial pattern of urban functional contact of the northeast cities is formedonecorridor,four cores,four groups,whichiscomplexruleandsignificantfeatures.
