In Northern Edge Of The Valley City Area Planning Study

River valley city in China North Shaanxi area develops remarkable status and function at the region economic society day after day, its city space unceasing extroverted expansion, the city fringe area has already become amore active area in the urban development, the river valley city fringe area development has been even more affecting the city overall function and the spatial shape. The North Shaanxi area river valley city faces the lack of urban construction land and so on with the city ecology the multiple development barriers, the fringe area space exists massively the space that can be used, how better plan this region, make it effectively bring into city function system, this has the practical significance to the river valley city's sustainable development. The domestic and foreign present studies concentrate much to the fringe area research in the big city, to special region, special city fringe area(For example: North Shaanxi area river valley city fringe area) are less. Meanwhile the study lack of the practice significance research case. Based on this situation, this thesis takes the North Shaanxi area river valley city fringe area plan research as a title, studied from the North Shaanxi area river valley city space development, profits from the domestic and foreign fringe areas plan the theory and the case research results, through Yenan Dongguan Yan River south shore this typical fringe area research, Attempts to construct a suitable plan method to the North Shaanxi river valley city fringe area.This article has first analyzed the North Shaanxi area river valley city space development rule. Next, through forms the analysis, the spatial characteristic analysis, the development problem analysis and the evolution analysis to the river valley city fringe area, summarized adapted the North Shaanxi area river valley city fringe area development pattern. Based on this, the article has discussed the fringe area plan idea, the core question and the plan technology route. Finally take the Yenan Dongguan Yan River south shore region as the example, has conducted the research to the fringe area plan.The this article main conclusion includes:1. The North Shaanxi area river valley city space development has the general rule of the river valley city space development; its core question lies in that because the city subordination loess plateau ecology frail area, the city space expands the difficulty compares other region's river valley city to be bigger.2. The North Shaanxi area city fringe area development pattern judgment should based on the fringe area spatial position analysis, according to the fringe area development localization analysis reasonable design fringe area development pattern.3. The North Shaanxi area fringe area plan, should highlight the ecology plan idea and the dynamic plan idea, pays great attention to the fringe area space dynamic control and dynamic guiding, enables the fringe area effectively to promote the city function consummation and the shape integrity, the increase river valley urban development efficiency. 4. Through to the Yenan Dongguan area plan research, summarizes to the plan of fringe area that approaches the city central area to be supposed to pay great attention to the region compound ecology function molding, simultaneously should strengthens the relationship through the transportation line reasonable layout, display each trench space, the Sichuan space and the mountainous region space.
