Analysis of the attraction field of urban human settlements:A case study of Dalian
社区人居环境吸引力研究——以大连市为例

The attraction of human settlements is becoming an important theoretical issue in the study of urban human settlements.In this paper,we first proposed the concepts of human settlements' attraction and human settlements' gravity field.Then,we constructed an index system for the environmental satisfaction of human settlements community and calculated the gravity field strength of 184 communities in Dalian using the gravitational potential energy model.Finally,we developed an isogram and spatial distribution map of gravity field strength of urban human settlements in Dalian with Vertical Mapper provided in MapInfo.The main conclusions of this study are drawn as follows.(1) Gravity field theory proves to be an effective method in evaluating human settlements.(2) The supply and demand of the human settlements community graphically has two centers and one coastal zone.(3) The gravitational potential energy of the human settlements community differentiates greatly in space.(4) The supply and demand of the community human settlement is proportional to gravitational potential energy,but inversely proportional to the distance between the community and the center of gravitational potential energy.The space development of the city and its coastal habitat is the main factor driving the distribution of environment gravitational potential energy in Dalian.
