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.展开更多

This paper describes current situation of the emerging urban green space system and analyzes different characteristics between current green spaces and the old city or existing urban green space. Considering green space system planning in the downtown area of Gu'an County, advantages of the "network + patch" layout for green space systems in emerging towns are summarized to explore a green space structure suited to these towns.展开更多

The population increase is mainly caused by rural to urban migration causing traffic congestion, unemployment, emerging of unplanned settlements, inadequate infrastructure, and social and housing services. In order to overcome these challenges there is an urgent need to establish and determine suitable locations of satellite towns to the outskirts of the central business district (CBD) to strengthen economic and social activities using reliable techniques. Selecting suitable locations of satellite towns has been determined by using distance from the CBD and population growth indicators. The limitations of using these indicators include unsuitable locations, which ultimately failed to attract economic growth in such areas. In this study, we introduce a new approach of selecting suitable location of satellite towns in fast growing cities. This approach uses Saaty Model and Geographic Information Systems techniques, whereby a pair wise comparison matrix, consistency index and consistency ratio are employed to determine suitable locations of satellite towns in Ubungo and Kinondoni Municipalities. Also, seven criteria were used to produce suitability maps for water, power line, road, communication line, elevation, slope and land use. The results obtained from this study show that about 5.31% of the area was classified as highly suitable, 29.82% as moderately suitable, 24.27% as marginally suitable and 40.6% permanently unsuitable. Locations of satellite towns determined using Saaty model was found to be on highly suitable areas whereas locations of satellite towns proposed by the Dar es Salaam master plan were located on marginally suitable areas. The study concludes that Saaty Model, if integrated with GIS, can be effectively used to determine suitable locations for satellite towns in urban areas.展开更多

The development of small towns is an important way to Chinese urbanisation. Land use plays a very important role in the development of small towns. However there are many problems in the development of small towns, esp. in land use. The paper first discusses the land problems in the development of small towns. Such as much cultivated land lies idle, under utilization and waste of land, increasing illegal use of land, unstable contractual relationship for land use. The relationship between the development of small towns and land use is also studied. Then the guidelines for the land system innovations of small towns are put forward. Namely the sustainability of social and economic development, the balance between land reservation and land utilization, the provision of service to village, agriculture and farmer, the management of land resource and land assets, the parsimonious and legal use of land. The basic framework of land system innovations of small towns is put forward finally. It include the land replacement policy for small towns and the permanent tenancy of farmland, the overall plan for land uses and other plans in harmony, the establishment of a flexible system of land supplies, using land with payments, the transfer of agricultural land and refining the land law related to the construction of small towns.展开更多

Based on the connotation and idea of cultural reproduction, in terms of application of basic theories of cultural ecology and restoration ecology, it had established tourism development of solid ancient towns, which had been analyzed specifically from the perspectives of representation of ancient towns'scene, cultural realization and cultural promotion. By taking Zouwa Ancient Town in the west of the main urban area of Chongqing City for example, it had discussed tourism development practice of ancient towns, emphasized making Zouma scene reappear from the aspects of pattern protection, restoration and treatment of ecological environment, ancient towns' protection and cultural facilities' construction, experiencing and publicizing Zouma culture. It also highlighted taking historical and cultural heritages as the theme of tourist products, and proposed development mode of solid ancient towns, realizing reproduction of cultural heritage.展开更多

Thus, this paper analyzed some actual cases in Guangxi which are successful in designing the overall image of small towns, including Cendou Xincun, Xing'an County and Yangshuo Dongling, found that all constructions show rich elements of traditional houses, characteristics of local houses and distinctive cultures of folk houses, and concluded that tradition was the source to construct the features of small towns, innovation was the basis to develop small towns and culture was the core to sublimate the features of small towns. It was considered that traditional architectures could only be integrated with modern architectures by fully excavating cultural characteristics of regional architectures, combining with regional tourism industry and motivating local people to participate in reconstruction, to enhance local styles and national features, and create a beautiful, comfortable and harmonious living environment, so the overall regional styles and features of small towns can be represented and proceeded, comprehensive competitiveness and strong vitality can be given to those towns.展开更多

文摘Since the 21st century, the construction of small towns in Guangxi Zhuang Autonomous Region has been accelerated obviously and has already taken shape, but there are still some problems such as old towns not being well protected, new towns constructed in unified style, regional culture not being excavated and town features without characteristics. Thus, this paper analyzed some actual cases in Guangxi which are successful in designing the overall image of small towns, including Cendou Xincun, Xing'an County and Yangshuo Dongling, found that all constructions show rich elements of traditional houses, characteristics of local houses and distinctive cultures of folk houses, and concluded that tradition was the source to construct the features of small towns, innovation was the basis to develop small towns and culture was the core to sublimate the features of small towns. It was considered that traditional architectures could only be integrated with modern architectures by fully excavating cultural characteristics of regional architectures, combining with regional tourism industry and motivating local people to participate in reconstruction, to enhance local styles and national features, and create a beautiful, comfortable and harmonious living environment, so the overall regional styles and features of small towns can be represented and proceeded, comprehensive competitiveness and strong vitality can be given to those towns.
