The methods of spatial statistical analysis, buffer analysis, Ripley's K function, kernel density analysis based on GIS(Geographic Information System) were used to analyze the characteristics of scale, spatial differentiation and spatial patterns of the rural settlements in Liangjiang New Area in Chongqing Municipality of China. The fractal dimension formula was also developed to reflect fractal feature of the rural settlements. The results show that, the scale of rural settlements in Liangjang New Area takes on distinct characteristics of spatial differentiation along with changes in elevation, gradient, location, geohazards distribution, and the like. The fractal characteristic of rural settlements has obvious regional variations subject to the 6 factors of location in the Liangjiang New Area. Overall, the worse the terrain conditions are, the larger the fractal dimension values become. The better the locationconditions, the larger the fractal dimension values are. The spatial pattern in the township scale presents three kinds of distribution as being aggregated, uniform and random. In contract, the spatial pattern in the plaque scale displays a banding distribution from a general view with several aggregation zones centering on each town center. From the results, we can see that the characteristics of rural settlements in urban fringe are more complicated. For such kind of rural settlements in special regions, in the rural land consolidation more attention should be paid to improve the rural living environments and public services, as well as to promote the harmonious relationship between the urban and rural areas.展开更多

It inctudes several complicated elements, such as population, space, and management organization. On the basis of local population attributes in the city fringe area combined with people＇s movement characteristics in time and space, this article reclassifies basic public service facilities and discusses the relationship between facility layout and housing, employment, and commuter transportation. Through a questionnaire survey in Qiaobei District of the urban fringe area in Nanjing and on the basis of comparative analysis, we discuss the impact factor on the choice of housing, urban services, and the tolerance of commuting time. Our findings indicate mutual promoting and restricting connections among living, employment, and services. Workers＇ living situation determines their daily behavior, such as dining, shopping, and entertainment. Furthermore, different income levels have a great influence on residents＇ choices with regard to places to live and develop their careers.展开更多

Urbanization has become the indicator of economic and secial deveopment in China. Rapid growth of oromy in China pushed the process of urbanization. Since 1978, China's urban non-agricultural population has grown from under 113.4 million in 1977 to 176.09 million in 1993. The number of cities increased from 188 to 617 in 1994. With urban economic activities making up an increasing share of GDP, preductivity of urban economy will heavily influence economic growth. In eastern coastal area, because economy of larger scale and agglomeration has been made more productive, the forces contributing to urban growth bome stronger.The number of cities has increased from 78 to 247 since 1980. Urban population was over 90 million. The urbanization level reached 31.5 peed. Four megalopolises have been emerged, they are : the Shanghai -Nanjing-Hangzhou region, the Pearl River Delta region, the Beijing-Tianjin- Tangshan region and the Shenyang-Dalian region. According to statistics, the area of these four regions occupies about 2.6 perat of China's total territory, but their GDP has exceeded 35 percent of the country's total. However, the rapid urbanization also resulted in a series of problems on deveopment and environment.展开更多

Closely related to urban-rural public welfare and regional ecological security, sustainable food supply, which is featured by various types, local production, and short-chain transportation, is an effective way to address the negative impact of commercial agriculture. This paper clarifies the important role of agricultural and forest land in urban fringe areas through analyzing the functional connotation and spatial bases of sustainable food supply, and proposes a planning strategy for systematic land protection and efficient spatial management in accordance with the current situation of food supply and compound demands in urban areas. Specifically, it consists of: identifying the land and the support space with potential for diversified food production;establishing an agriculture and forestry support network system and integrating it into regional landscape ecological network;guiding the low impact utilization of production units by following the natural process and resource characteristics;enhancing land protection efficiency based on supporting links.展开更多
