Research on New Urban Area Planning Based on TOD Mode:A Study on Binhu New District of Hefei City

As an urban development mode,the TOD (Transit-oriented Development) mode,targeted at energy-saving and based on the public transportation system,has positive significance for solving problems like disordered urban sprawl and traffic congestion in Chinese cities.This article takes Binhu New District of Hefei as an example to illustrate the practice of the TOD mode in the urban design of large and medium-sized cities.The paper analyzes the relationship between the new district,central urban area,and public transportation development,and puts forward that the TOD mode is suitable for Bihu New District.It states that the TOD mode can be realized through methods such as the building of a "double-rapid" comprehensive public transportation network,the setting up of decentralized-compact urban clusters and TOD communities,the mixevd land-use,as well as the scenery design with complete walking space.The paper also proposes that certain flexible methods can be adopted in order to promote the TOD mode,including making full use of bus transit when rail transit is lacked,setting up TOD communities surrounding the transport hubs,etc.

Analyzing land use characteristics of rural settlements on the urban fringe of Liangjiang New Area, Chongqing, China

The objective of this paper is to analyze land use characteristics of rural settlements in urban fringe so as to provide references for optimizing the regional distribution of rural settlements, consolidating rural settlements, and coordinating urban-rural integrated development. 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.

Research on the Harmonious Development of New Rural Communities under the Perspective of Balancing Urban and Rural Areas

On the basis of offering a definition of New Rural Communities (NRCs), the paper analyzes the values of New Rural Communities and argues that the construction of NRCs is able to contribute to the enhancement of the comprehensive agricultural production capability as well as the development of social productivity. Meanwhile the incomes of the rural residents can be boosted, which denotes the realization of a harmonious society where the achievements of China's reform and development are shared by each citizen. Moreover, the construction of NRCs facilitates the economization of land use and thus improves the overall living standard of the residents, while helping to cut the administrative cost and promote democracy at the primary level. This paper also points out various problems arising during the construction of NRCS in China: blindly following suit in accordance with the modes of the urban communities; lack of funds, which leads to the absence of the supporting mechanisms of NRCs; vague positioning and the ensuing shortage of impetus for continued development. Finally, the paper raises the corresponding measures and suggestions: first, based on reality, make overall planning and scientific arrangement; second, the government should play the dominant role while respecting the principal position of the rural residents and introducing the market mechanism; third, increase science and technology input and attach equal importance to economic and social benefits; fourth, broaden fund-raising channels while completing the supervision mechanism.

城乡均衡发展大格局下我国公路服务区大网建设研究

当前我国高速公路服务区功能与畅通全国城乡产销大循环要求存在五大矛盾:一是服务区封闭,过路消费需求与沿线乡镇农特产品供给脱节;二是旅客上下中转受限,营运公司客流补充成本高昂,始发终到旅客集散时间成本猛增;三是小批量物流快件不能直接沿线集散,私营公司抢占赢利路线而弃舍高速沿线乡镇小批量件;四是旅客需求日益多样化,服务种类相对国外而言极其单薄;五是城市停车难,关键要靠市郊和城乡路网。建设开放型服务区且注重城乡均衡布点成网,是日韩和法德推动消费惠及城乡的重要成功经验,服务区集应急救援、旅客集散和换乘中转、物流仓储和快件集散交换、本地农特产售卖以及旅游观景休闲等商旅文于一体已成未来发展大势。在我国公路沿线建设数以万计的综合服务区和各类中小微网点,利用网点换乘中转实现全国客货邮“镇-镇”直达,可以更充分地发挥现有高等级公路的网络共享优势,更有效地实现客运增流、快递增质增量、城乡产销提质增速等国内双向大循环功能,将全国人民的日常经济社会活动汇集成为城乡一体共享生产、交换和消费大市场,助推实施乡村振兴,促进城乡融合发展。
