摘要
城市人工地貌是城市中由人类活动作用形成的各种高差起伏的人工建筑体的组合形态 ;本文以大连市为例 ,探讨了城市人工地貌的演变过程及机制 ,大连市城市人工地貌演变过程分为单核心扩散—绕大连湾的马蹄形延展—环形带状更新扩散期—多核心扩散、带状延展期 ;自然地质条件是演变的基础 ,城市规划是主导因素 。
Urban man-made landscape is a combined conformation of various kinds of artificial buildings by collective human activities.It has a variety of configuration and evident adumbration as well as the characteristics of discontinuity and irreversibility. The development of the urban man-made landscape of Dalian,different from the general development law of the urban man-made landscape,witnesses the fallowing process of the spread of the single core extent in the shape of a hoof--the annular banding spread--radiation of multicores, the spread of belt . Its development mechanism is based on geological condition. Urban planning acts as its leading factor,while socio-economic development as its motive force. Probing into urban man-made landscape essential feature and development mechanism on time and space distribution can offer efficient decision basis for the development of urban construction and the protection of the fragile urban eco-environment.Whether the development of the urban man-made landscape is rational has important influence on urban construction and urban environment. The orderly and rational development will bring prosperity to the city; otherwise it will not only bring confusion to the development of the city, but also cause urban feature stereotyped,which will reduce the economic value of the city and cause a series of urban environmental problems.So we put forward some views on the development of the city in light with urban man-made landscape to policy makers for their reference:1)geological survey and mapping work,should be fully carried out so as to offer scientific basis for rational urban planning;2)urban construction and development plan should have certain leading in order to guarantee the historical continuity in the development of urban man-made landscape;3)the development of urban man-made landscape should give prominence to the nature and function of the city by highlighting its distinct individual character;and 4)the development of urban man-made landscape should take people's benefits first, and urban construction should pay even more attention to environmental protection.Substantial development of urban man-made landscape will cause expansion of space dimension size to a certain extent,inducing a series of urban eco-environmental problems. So, the harmonious sense of pursueing'harmony of man with nature' just should be a supreme goal of the urban construction.
