中文摘要：
村镇空间是一个城乡社会、经济关系交融的复合系统,具有空间关联性与层次性。本文以大冶市为例,应用空间相互作用理论,基于改进重力模型构建大冶市空间网络,识别村镇相互作用的关系,根据关系强弱划分强势村、一般村与弱势村。结果表明：大冶市村镇相互作用力呈现出由四周向中心集聚的态势,且强势村多分布于城镇周边与交通沿线,弱势村多分布于地形复杂和交通可达性较低区。基于改进重力模型构建的村镇空间网络,能够较好地反映村镇发展的关联特征与强弱联系,从而为村镇区域农村居民点规划布局提供科学的决策依据。
英文摘要：
The space of villages and towns is a compound system of urban and rural social and economic relations,which has the spatial correlation and hierarchy. This paper takes Daye county as an example,applying spatial interaction theory,and builds the spatial network of Daye based on the improved gravity model,in order to identify interaction relations of villages and towns,and to divide those villages involved in the research into strong villages,general villages and weak villages according to the relationship. Results show that the interaction has a tendency of agglomeration from the around to the middle,and strong villages are distributed in the neighborhood of towns and along the traffic,while weak villages are located in the area with complex terrain and low traffic accessibility. The spatial network based on improved gravity model can well reflect the correlation characteristics and the contact of the development of villages and towns,which provides scientific decision basis for rural residential areas’ planning and layout.
