长江三角洲新型城镇化发展问题与态势的判断   总被引：4，自引：2，他引：2  

陈雯  闫东升  孙伟 《地理研究》2015,34(3)

长江三角洲地区是中国经济最发达、人口最密集、城镇化进程较快的地区。当下,面对全球化深入发展、国家及区域经济社会转型等背景及资源环境瓶颈压力趋大等因素交互影响,长三角城镇化发展特征和格局出现了新的变化。城镇化发展关系经济社会发展各个方面,更是与人口、资源、经济要素的流动及变化息息相关。因此对长三角城镇化发展态势的研究,从人口流动、用地变化、经济增长等要素演化及其互动协调关系入手,进而对城镇化与工业化进程、土地与人口城镇化的步调、城市外来人口的市民化走势、城乡关系中的乡村衰退与复兴趋势、城镇化发展的粗放与集约等关系问题进行了深入分析和探讨,并提出相应的发展路径与制度建议以及今后新型城镇化需要进一步研究的主要科学问题。  相似文献   

尺度推绎研究中的几点基本问题   总被引：49，自引：3，他引：49  

赵文武  傅伯杰  陈利顶 《地球科学进展》2002,17(6):905-911

尺度推绎作为将一个尺度上的信息推绎到另一个尺度上的过程,具有尺度依赖性、模型非线性和研究的复杂性等特征,其理论基础主要有等级理论、分形理论等,其研究的关键问题表现为尺度选择与信息提取问题、尺度域与特征尺度问题、模型问题等方面。针对相邻尺度推绎和跨尺度推绎两种情况,还介绍了不同情况下尺度推绎研究的基本思路。尺度推绎作为现代地学、生态学等学科研究的重要问题之一,其发展需要多学科的交流和理论与技术的创新。  相似文献

An application of problem and product ontologies for the revision of beach nourishments     

D. Van de Vlag  B. Vasseur  A. Stein  R. Jeansoulin 《International journal of geographical information science》2013,27(10):1057-1072

An ontological approach in GIS serves as a framework for the conceptualization of processes in the real world. In this paper, we examine an application in coastal change in the Netherlands, whereby beaches are subject to artificial nourishment to offset the effect of severe erosion. The use of ontologies helps to define two scenarios: S_I determined by the regulations from the Ministry for Public Works; S_II grounded on the abilities from an existing spatial dataset. A comparison between S_I and S_II shows that 72.8% of the objects suitable and unsuitable for nourishment are correctly classified. A higher overlap is found in areas where actual beach nourishments were carried out. Inaccuracies in attributes influence the determination of the objects. A sensitivity analysis applied to altitude illustrates a significant increase of objects suitable for nourishment for both scenarios, when altitude is decreased within the lower limit of the root mean square error for the 95% confidence interval. Moreover, the sensitivity of altitude shows that artificial boundaries for beach nourishment objects are not reasonable and consequently should be treated as vague objects.  相似文献

联合国气候变化框架公约适应委员会职能谈判焦点解析   总被引：1，自引：0，他引：1  

马欣  李玉娥  仲平  王文涛  刘硕 《气候变化研究进展》2012,8(2):144-149

在《联合国气候变化框架公约》(简称《公约》)下建立适应委员会是当前气候变化国际谈判中发展中国家和发达国家争论的焦点之一。通过对《公约》下现有机构的职能分析和已开展的适应行动的回顾,提出适应委员会需赋予适应规划、政策制定、资金需求评估、项目实施、协调区域中心等关键职能。针对谈判中的焦点问题,发展中国家应坚持以下三点：将适应委员会建立在《公约》之下,提高适应委员会的作用;发展中国家在适应委员会中占多数席位;适应委员会与资金和技术机制直接联系,落实开展具体适应活动的资金和技术支持。  相似文献   

The Basin Water Resources Management System and Its Innovation in China     

Fengrui Li  Xun Pomponio  Qijun Liu 《寒旱区科学》2008,(1):0105-0114

Water provides the origin of human survival and prosperity,and the basic resource for the maintenance of terrestrial eco-systems,their biodiversity,productivity and ecological services.With China’s recent,rapid growth both in population and economic development,the water shortage has become one of the most constraints on its ecological restoration and socio-economic development,especially in the arid inland regions of northwest China.At first glance,this water shortage in China appears to be a resource crisis.But second,an in-depth analysis reveals that the water shortage crisis arises mainly resulting from the poor water management system and operating mechanism that cannot facilitate fair allocation and efficient utilization of water resources both regionally and nationally and thus is viewed as a crisis of water manage-ment.The solution of China’s water shortage and low-efficient utilization problem will,in particular,require a fundamen-tal and substantial reform or innovation of the existing water management system and operating mechanism.In this paper,we address explicitly the problems existed in the current water management system,explore the basic theory of water re-sources management and provide some insights into the way how to establish a river basin based integrated water re-sources management system in China.  相似文献
