Abstract
The loess plateau region in northern Shaanxi province in China is characterized by loess hilly and gully, fragile ecological environment, scarcity of land resources. The delimitation of space growth boundary is critical to the intensive use of land resources and the compact development of space. How to delimit the compact space growth boundary becomes the focus of attention and research. The urban space growth boundary is one of the earliest urban land management policy tools adopted by the United States under the new urbanism in the West. The concept was presented in 1976 by Salem, Oregon, USA [1]. Its goal is to curb the social, economic and environmental problems brought about by the spread of the city. Urban space growth boundary is not to curb the development of the city, but through the space boundary to limit the development of the city in a clear geographical space. Thus, city's disorder expansion is blocked while meeting the needs of urban development [2]. Once the urban space growth boundary has been put forward, it has become one of the hotspots of urban planning. Many scholars at home and abroad are committed to many aspects of practice and research, such as the concept of its connotation and impact analysis, the formation of mechanism analysis, delineation methods and related management strategies, application in planning [3-7]. In the traditional urban space growth boundary delimitation method, mainly in static analysis, dynamic simulation of two types of methods, the specific technical means, including ecological suitability evaluation, binding CA model, BP neural network, SLEUTH model [8-10]. In the planning practice, planners often use the urban ecological suitability evaluation, and then take the empirical value to delimit the urban space growth boundary. And also some scholars have made a reference to the overall planning of urban construction land to determine the scope, that is, plus 25% of the floating rate on the scale of the construction land in master plan [11]. In general, different demarcation methods have their own strengths. But the association with the goal of urban space growth boundary is weak, which is the intensive use of land. In addition, there is a lack of adaptability research between two elements, regional natural terrain conditions and urban surrounding ecological environment factors, the urban space growth boundary and its urban space development trend adaptability, the urban space growth boundary and urban space development endogenous needs [12]. In this paper, the method of delimiting the boundary space of urban space has made a response to this problem, which is of great significance to the compact growth of urban space.
