Study on Spatial Structure and Response of Towns and Villages System——with Dongzhai Town in Ningwu County of Shanxi Province as a Study Case

Taking Dongzhai Town in Ningwu County of Shanxi Province as example, this essay explores the spatial structure of towns and villages system from the following perspectives: scale structure, function structure, structural characteristics of village land-use, and spatial distribution characteristics of Dongzhai villages. There are 5 grades of villages according to their scales, that is, villages have a population over 1 000, between 500 and 1 000, between 100 and 500, less than 100, less than 50. The function structure of Dongzhai Town is divided into 3 grades, Grade 1 (core village), is village with such functions as tourist service, transportation and distribution function. Grade 2 (characteristic village), is agricultural settlement with functions such as industrial function, transportation service, tourist service, and forestry function. Grade 3 (general village), is agricultural settlements with prominent agricultural functions (dry farming). This essay also predicts the change and responses of this town based on the population forecast models. It is predicted that the population of Jiancheng District will reach 4 750 in 2010, 6 400 in 2015, 8 700 in 2020. Returning farmland to forests in Fenhe River valley can ensure the conservation of water resources and the development of tourist service. The proportion of forest land, especially bushes land, and proportion of grassland, especially artificial grass will increase dramatically. The number of slope land will be down a bit. The Lands for settlement and transportation will increase with the development of ecological migration and tourist service. Specialized land such as water area and places of interest will skyrocket. Village patterns and spatial distribution under the system of towns and villages will be improved as well.

The Research on Protection of Historical and Cultural Towns and Villages in China

After the discussion of the protection process and significance for historical and cultural towns and villages and the introduction of survey and theoretical researches on them,five modes had been divided for the protection of historical and cultural towns and villages in China,which were original appearance protection,renovated utilization protection,removal protection,antique imitation development and real estate development.It had pointed out problems existing in historical and cultural villages' protection,which were that policies and regulations were incomplete and protective measures were laggard;leaders decided blindly and neglected experts' opinions;immediate interest had been highlighted and sustainable development been overlooked,capitals were lacked and management was disordered,and the publicity was insufficient and the masses had no high protection consciousness.On this basis,it had discussed the protection of historical and cultural towns and villages in the future,emphasized the completion of regulatory system and management mechanism,enhance capital investment and publicity education,and deeply explore material cultural heritages and non-material cultural heritages in historical and cultural villages,finally further studying the theories and cases.

Environmental Improvement Problems of Village in Town and Countermeasures

The improvement of urbanization level in China and long-term development of economy in vast rural areas commonly impel rapid development of urbanization in China by " stronghold type" of small town and " radiation type" of big town. Urbanization road with Chinese characteristics impels urbanization and industrialization development,which needs relying on the development of small town. Due to the impact of town,space environment of " village in town" changes,and rural memory weakens. The state of " non city and non township" deeply affects rural development. Meanwhile,due to limited by urban-rural dualism,top-down planning of " village in town" is obviously unworkable. In this paper,analysis and interpretation on the problems of " village in town" are conducted,the cause is found,and effective channel of solving problem is obtained.
