摘要
空间引力模型是相互作用理论的重要组成部分,主要用于空间影响范围的划分.在全面评述现有研究成果的基础上,提出了基于地图代数障碍距离变换的空间引力模型研究的新思想.该方法利用空间引力模型判断各个城镇的吸引力,并应用基于地图代数障碍距离变换的度量方式求解距离参数,从而界定区域的城镇空间影响范围,并将结果与Voronoi图方法相比较.理论和实践证明,该方法可以更好地刻画城镇的空间吸引特征.最后,对将来的研究方向进行了展望.
Spatial Gravity Model is an important component of interaction theory,it was mainly used in delimitation of influenced spatial regions. This paper raises the new ideas of Spatial Gravity Model based on Obstacle Distance Transform of Map Algebra on the basis of a comprehensive review of existing research results. This method determines the attractiveness of various cities and towns using spatial gravity model, and it solves the distance parameters by applicating metric methods based on obstacle distance transform of map algebra to definite the urban spatial influenced regions. The results is compared with Voronoi diagram method as well. Theory and practice has proved that this method can portray the characteristics of urban spatial attraction better. Finally, the outlook of the future research directions is put forward.
