Study on the Spatial Coordination Pattern of the Urban and Rural Areas——Take the Northern Shaanxi Loess Plateau as the Example

摘要

It is the one of the most important issues to coordinate the spatial development of urban and rural areas in the process of rapid urbanization. This paper takes the fiver valley in Northern Shaanxi Loess Plateau as case study,analyzes the unique environmental characteristics of the dense gullies in river valley and discusses the ecological driving force produced by fiver valley to human settlements. Furthermore, the author proposes the spatial development pattern adapting the valley terrain according to the research findings of its aggregation effect, watershed effect, transmission effect and confluence effect. The spatial pattern advocates that parts of residential area of cities develop away from the main dver valley towards small basin surrounding it. The pattern can block agriculture land taken by urban expansion, and form the Yao dong residential areas of cities and towns. It has bright prospects for the further development of the 'gene'—original harmonious feature of human settlements. The value of the pattern is that it can promote the effective combination of urban area, rural area and natural environment and form the new spatial complex that is beneficial to narrow the differences between urban area and rural areas. It shows the way of urbanization based on spatial coordination should have the local characteristics under the different situation of natural environment, social and economical conditions.
