城市人工地貌过程对城市化的响应——以大连市为例

城市人工地貌是城市中由人类活动作用形成的各种高低起伏的人工建筑体的组合形态,随着城市化进程的不断推进,城市人工地貌的发育表现出了一定的规律。本文以大连市为例,建立了城市人工地貌发育过程对城市化的响应模型,同时,研究了城市人工地貌发育与城市化进程变化的耦合系数,在此基础上分析了城市人工地貌过程对城市化进程变化的响应,最后得出了大连城市人工地貌在城市化作用下的发育规律。

Response of Urban Man-made Landscape to urbanization:the case of Dalian

Urban Man-made Landscapes are vario us rising and falling artificial landmark associations that are formed by human ac tivities. With constant promotion of urbanization process, the development of Urban Man-made Landscapes demonstrate certain law. This study, taking Dalian as an example,` has set up the responding model to the urbanization development course of Urban Man-made Landscapes. Meanwhile, this thesis studied the coupling coefficient of Urban Man-made Landscape development and urbanization process changes. Based upon the above analysis it also analysed the response of Urban Man-made Landscapes to the changes of the urbanization process.Finally, the deve lopment laws of Urban Man-made Landscapes of Dalian under urbanization function are summaried.The main conclusions of the study are as follows: (1) The responding equatio n of Urban Man-made Landscapes of Dalian city under urbanization function accor ds with actual conditions of Dalian, meanwhile , the responding equation is basi cally identical with urban growth curve,which proves that this responding model is accurate and reliate.(2) The development of Urban Man-made Landscapes of Dalian demonstrates the obvious stages with stages of the urbanization process, which proves the inherent regularity of the two changes.(3) The changes of respon ding coefficient and coupling coefficient of Urban Man-made Landscapes of Dalian are consistent,namely, the greater the responding coefficient, the greater cou pling coefficient is.The consistency of the two has confirmed the accuracy of this responding model further.(4) With constant promotion of the urbanization process, the development of Urban Man-made Landscapes of Dalian experiences a three-mode expansion with level space in domination-level expansion with vertical growth in coordination-vertical space growth of city in domination.
