基于GIS的辽宁省城镇化空间演变特征分析

Analysis of urbanization spatial evolution characters based on GIS in Liaoning province

城镇化空间演变特征的分析是研究区域城镇化发展的关键.在梳理相关研究成果和研究方法的基础上,采用多维度综合评估、GIS技术空间分析的方法,选取人口、产业、用地、教育、居民服务5个指标,探讨辽宁省城镇化空间演变特点,以及5个指标间的协调关系.通过对辽宁省的实证研究发现,人口、产业、教育、用地、居民服务的城镇化指标值在空间演变方面既有相同点又存在差异性.高值区主要分布在沈阳、大连及其周边城市,而辽西北地区各项指标值一直处在较低的水平,城镇化地区发展不均衡,两极分化严重;随着城镇化速度加快,各要素在发展变化过程中的冲突与矛盾增多,指标间表现不协调.

T he analysis of urbanization spatial evolution characters is the key to study the development of regional urbanization .On the basis of combing relevant research results and their methods ,Using the methods of multi-dimensional comprehensive evaluation and GIS spatial analysis and selecting five indicators about the population ,industry ,land ,education and resident services ,it is explored that the features of urbanization spatial evolution in Liaoning province ,and the coordination of relationship between five indicators .Through the empirical research in Liaoning province ,we find that there are both similarities and differences for the five indexes in the aspect of spatial evolution .High value are-as are mainly distributed in Shenyang ,Dalian and its surrounding cities .However ,the northwestern Liaoning of the various indexes value have been in a lower level ,the regional development of urbani-zation is unbalanced ,Polarization is serious ;With the accelerating pace of urbanizaton ,the elements of conflict and contradiction in the process of development and change is increasing ,and there are lack of coordination between the indicators .
