An Evidential Analysis on the Rural Urbanization Development in Chongqing

The rural urbanization process in Chongqing is much slower than that in other metropolitans and most of the provinces in eastern China, which can't adapt to its important function as the economic and cultural center in southwestern China.It is urgent for Chongqing to accelerate the rural urbanization for improving its whole urbanization level and speeding up its economy development to catch up with other metropolitans and some advanced provinces.Compared with the urbanization in other metropolitans and some provinces, the authors demonstrated the rural urbanization situation and its characteristics in Chongqing in details, analyzed the reasons for the poor urbanization and its influences on the social-economic development especially that in the rural area.Inferior position of Chongqing's small towns in the market competition with those from other provinces is one of the results of its poor urbanization development.At last, the authors suggested a few practical countermeasures to improve the rural urbanization in order to get a rapid and sustainable rural development and to increase the whole economic effects of the metropolitan.     

Development of Towns in Chongqing and Its Problems

To further accelerate the development of towns is a necessary route to realize urbanization in China. Based on current situations in Chongqing, this paper studies the related development theories and practice. It also analyzes the difficulties and opportunities faced currently. It can be used as reference for the development and construction of towns in our country.     

Study on Pattern of Urbanization Development in Chongqing

As a municipality directly under central government, Chongqing has a dual economic structure. We can't break away from its history and realistic condition while studying its urbanization development model. In this paper, taking the theory of urbanization development as the foundation, fully using the experience in urbanization of developed area for reference in combination with the reality in Chongqing, the urbanization development model for Chongqing is put forward as "metropolitan area + dot-axle type town strap", that is, taking metropolis area as the center and Yangtze river and Line 319 (Yuhai Railway) as the development axle and the towns along the axle as the node, the development is carried out like a string of beads to form a network type urban system with metropolitan area as center and cities such as Wanzhou, Fuling and Qianjiang etc along Yangtze River as the regional center.     

Analysis on Economic Cost for Urban Development--A Case Study on Chongqing Municipality

基于回归分析的重庆市长寿区城镇化进程中的耕地保护问题研究

“十一五”期间,重庆市长寿区城镇化快速发展,同时耕地资源大幅减退,经济发展矛盾日益突出。为了保护长寿区耕地资源,保证粮食安全,缓减城镇化发展面临的资源压力,通过建立回归模型,定量分析长寿区城镇化与耕地资源变化的关系,以求促进经济社会可持续发展。结果表明,城镇化的快速发展是耕地资源减少的直接动因,城镇化程度越高的地区,耕地面积减少越大,从而提出优化空间布局,加强农用地转用管理,开展土地整治,创新土地管理制度等措施解决耕地问题。

Problems in the Development of Small Cities and Towns in West China and Countermeasures: A Case Study of Luzhou City,Sichuan Province

New urbanization targets at coordinated urban-rural development, and construction of ecological and livable environment, it is the foundation for breaking urban-rural dual structure of China and promoting the agricultural modernization. Small cities and towns as carriers of new urbanization have already become important paths of realizing new urbanization and solving problems concerning 300 million peasants in China. Considering the requirements of new urbanization, this paper took Luzhou City in Sichuan Province for example to explore development path suitable for small cities and towns in west China and gave pertinent suggestions.     

Economic Loss Assessment of Ecological Damage of Land Resources in the Process of Urbanization:A Case Study of Wanzhou District, Chongqing City

With the improvement of urbanization's level, the destroys of land resources become severer and severer, and the expense is huge. According to their features, land resources can be classified as environmental loss, available ecological loss and land restoration costs. By studying the principle and technique of evaluating these three losses, we put forward quantification pattern of ecological loss of land resources. The research of Wanzhou district, Chongqing city indicates that the number of total ecological loss of land resources during the urbanization from 1995 to 2001 is about 344.70 millions yuan, it is 4.70% of GDP in 2001. In the mass, Wanzhou district is not in a sustainable development because the ecological loss of land resources during the urbanization continually increased.     

基于SWOT分析的河南省城镇化发展策略研究

研究旨在分析河南省现阶段城镇化的发展水平,了解其优势及问题所在,在此基础上得出未来城镇化发展的相关策略,以推动其持续健康发展。以河南省城镇化进入历史转型期为切入点,运用SWOT分析方法,明确了当前的城镇化建设在历史文化、区位交通及国家政策等方面拥有显著优势,并揭示了城镇化进程中存在的诸多问题：城乡发展不均衡、基础设施建设及产业发展滞后、“城市病”频发及人口素质和资源环境的制约等。以此为依据,提出未来河南省的城镇化建设应集中力量做好四件事：以“新三化”协调发展助推新型城镇化建设;加快城乡一体化建设,全力缩小城乡差距;加大生态环境保护力度,追求可持续发展的新型城镇化;注重农村人口素质提升,助力城镇化转型升级。     

On Development of Small Towns and Estimate of Urban Land - use - A Case Study in Dazu County, Chongqing

The urbanization level and demand of urban land-use in future are forecast on the basis of natural condition, social and economic environment and the present condition of development in Dazu County. In the future, the supply-demand contradiction in urban land will be more intensive with acceleration of urbanization. Therefore, on one hand, urban land in major towns should be increased properly with centralization and land rearrangement of rural settlements;on the other hand, utilization ratio of land should be improved with enhancement of intensive use of urban land. In Dazu County, the demand of urban land should be satisfied primarily in towns with strong economy and urban land use should be increased properly in towns with general economic level but with potential economic development in the future. As for other towns, the urban land-use increase should be controlled.     

基于能值生态足迹的陕川渝三地可持续性发展对比分析

能值生态足迹法（EEF）是一种基于生态足迹的对区域生态系统的可持续发展状况予以评估的能值分析方法。以陕川渝三省（市）为研究对象,利用人均能值生态承载力和人均能值生态足迹以及万元GDP对2007年三地生态经济系统可持续状况进行了分析,并就陕川渝区域之间合作的优先性从可持续发展的角度予以客观评价。结果表明：2007年陕川渝三地的能值生态赤字分别为3.604hm2、1.467hm2、1.268hm2,万元GDP生态足迹分别为3.162hm2、2.31hm2、1.632hm2;三地均处于不可持续发展状况,且陕西的情况最为严重,资源利用效率最低;陕川渝三地的发展各自面临一定的资源短缺问题,依靠进口或者过度开发来为维持社会经济的高速发展,势必会引发一系列的生态问题,在新的时期原有的以环境为代价发展经济的传统发展模式遇到了挑战,只有因地适宜地对这种模式进行优化调整,才会使陕川渝各地的发展持续化,从而推动西部发展。     

Update Planning and Design Concepts of Taiping Old Downtown Areas in Shuangliu

China has witnessed unprecedented rapid and massive urbanization in recent years, and the urbanization has infl uenced almost all corners of the country, which is a natural process and necessary result of the social and economic development. Development and expansion of cities has been the keynote of the contemporary era. Meanwhile, existence and future development of traditional urban areas that have gone through the long-term natural development have been faced with serious crisis. This paper focused on the relative constancy and changeability of major elements in the natural evolution of traditional cities and towns, so as to explore an organic development mechanism, and make a daring attempt in update planning of old downtown areas of Taiping Town in Shuangliu County. On this basis, the paper aims at exploring a new development concept for common cities and towns that balances inheritance and innovation.

兰州市城市化与土地集约利用耦合协调性及关联分析

为了深入探究城市化与土地集约利用的动态关系和互馈机制，促进城市可持续发展。本研究运用耦合协调度模型和灰色关联模型对2006—2015年兰州市城市化与土地集约利用的耦合协调以及关联性进行了分析。结果表明，兰州市城市化和土地集约利用综合指数均呈上升趋势，且总体上土地集约利用水平超前于城市化水平；耦合协调状态由中度失调逐渐转为优质协调，逐步趋于协调发展；城市化与土地集约利用2个系统之间互相关联，土地集约利用中的产出效益对城市化的影响最为明显，而社会城市化和生态城市化是影响土地集约利用的主要因素。在未来发展中，应发挥土地集约利用对城市化的反推作用，促进城市化进程，进一步提高协调性，从而推动城市可持续发展。     

城乡结合部农村建设用地集约利用评价及空间格局分析——以重庆市九龙坡区为例

为了缓解和解决城乡结合部地区城乡发展用地矛盾突出,以及农村建设用地集约利用水平较低的问题。以重庆市九龙坡区10个乡镇为研究对象,选取具有城乡结合部代表性人均居民点面积、耕居比、农村居民点人口密度、人均粮食单产、城镇化率等13个评价指标,建立城乡结合部地区农村建设用地集约节约利用评价指标体系,采用特尔斐法、层次分析法和多因素综合评价法分析对城乡结合部地区农村建设用地集约节约利用水平进行评价。根据其集约利用程度将10个乡镇分为3个等级,并以ARCGIS 9.3软件为技术平台,分析了研究区内农村建设用地集约利用水平的空间格局和聚集规律。结果表明,研究区域内农村建设用地集约利用的变化趋向在东北—西南向上为最为明显,而与之相反的西北—东南向的变化趋向较为平缓,并阐述了当前城乡结合部地区农村建设用地集约利用低效的原因,提出了提高城乡结合部地区农村建设用地集约利用水平的措施和建议。     

区域城市化阶段划分与粮食播种面积变化

为了明确三峡库区（重庆段）各区（县）城市化阶段与粮食播种面积变化驱动力分区,并明确对应城市化阶段与粮食播种面积变化驱动力分区之间的关系,笔者运用了统计分析法、层次分析法、模糊综合评价法进行研究。研究结果表明：（1）研究区城市化率增长速度快,根据城市化率确定了不同时期各区（县）所处的城市化阶段;（2）粮食播种面积总体上呈现下降趋势与“适度增加—急剧减少—小幅增加—小幅减少”的状态,并且区（县）差异明显;（3）粮食播种面积驱动力空间分区可分为最优型经济福利—生态安全驱动区、最优型经济福利—粮食安全驱动区、生存型经济福利—粮食安全驱动区;（4）确定了研究区城市化阶段与粮食播种面积变化驱动力分区的对应关系。此项研究有利于缓和粮食安全保障与经济发展的矛盾,也可为研究区制定差异化的粮食安全保障措施提供参考。
