A CASE STUDY ON CONCENTRATION AND DECENTRALIZATION：BEHAVIOR AND DYNAMIC MECHANISM OF SPATIAL EVOLUTION IN METROPOLITAN AREA，NANJING，CHINA   总被引：1，自引：1，他引：0

In rapid socio-economic development,the process of concentration and dispersal of various elements tends to be more dramatic,tremendously influencing the shaping and transformation of the space in metropolitan area.Survey of spatial concentration and decentralization has thus become a basic method in examining metropolitan spatial evolution.In this research,three elements were selected as the essential indicators of the process:demographic density distribu-tion,employment density distribution and business office location.Performance of these elements in Nanjing City was exam-ined historically.As Nanjing City could be regarded as a representative of metropolitan areas in China,its situation large-ly suggestes the general characteristics in similar areas of China.Hence based on the investigation of Nanjing City,four general implications were highlighted.First ,metropolitan areas in China are in a violent process and shift of spatial concentra-tion and decentralization.Second,from now to at least the near future,concentration will continue to be the central fea-ture.Third,the landscape of metropolitan areas basically exhibits a dual structure character.The gap in environmental and ecological qualities among different districts will continue for a long time.Fourth,Central Business District (CBD) is playing an important role in helping to convert the traditionally single-centered city structure into a polycentric one.  相似文献

河南省《贯彻国务院关于加强土地调控有关问题通知的意见》解读之三：建立新的土地利益分配机制     

《河南国土资源》2006,(11):9-9

我省《贯彻国务院关于加强土地调控有关问题通知的意见》明确指出,土地管理工作今后要强化征地补偿制度,保障被征地农民的长远生计;要规范土地出让收支管理,落实建设用地税费调整政策;要执行工业用地出让最低价标准,实行招标拍卖挂牌出让。这些政策措施的核心,就是从体制和机制  相似文献   

完善机制保障农民合法权益     

嘉兴市人民政府 《浙江国土资源》2003,(6):10-11

近几年来。嘉兴市在推进城市化进程中，土地征用的面积较大。从1993年至今。嘉兴市区城市规划内累计征地6．5万余亩。涉及失地农民4．86万人。如何妥善处理好土地征用与土地承包之间的关系，保护被征地农民的利益。解决好被征地农民的社会保障问题。是摆在各级政府面前的一道课题。市区从1993年起。开始探索“土地换保障”的征地新机制。使失去土地的农民得到了长期的基本生活保障。城市化得到稳步推进，达到了经济发展和社会稳定的双重目标。  相似文献   

土地信访工作的实践与对策     

胡萃利 《浙江国土资源》2003,(5):36-38

信访工作历来是我党和政府发扬民主、体察民情、接受群众监督的重要渠道，是联系群众的“桥梁”和“纽带”。党的三代领导都十分重视信访工作。党中央也曾反复强调，新时期“信访工作只能加强不能削弱”。土地信访是党的群众路线和群众工作的重要组成部分，也是国土资源管理工作的重要组成部分。国土资源管理的各项政策法规能不能得到有效地贯彻执行，很大程度上要取决于人民群众是否真心拥护和支持。土  相似文献   

城市房屋拆迁中土地使用权补偿价值的探讨

城市建设中,原有国有土地和城市规划区内经征用可以转化为国有土地的集体土地是房地产投资开发的重点。旧区改建和新区开发都必须从土地所有者和土地使用者那里获取土地进行开发建设,无论是对生地、毛地、还是熟地进行投资建设,原存在于国有土地上的房屋均必须在拆迁期限内限期拆除,由拆迁人对被拆迁人  相似文献   

征地补偿分配应当体现土地承包经营权的权益     

尤文郁 《黑龙江国土资源》2006,(11):34-35

在贯彻落实国务院《关于深化改革严格土地管理的决定》完善征地补偿办法中，一些地方提出在适当提高补偿标准的同时，有必要调整集体和被征地农户在征地补偿分配中所占比重，把补偿的“大头”分配给被征地农户，以体现土地承包经营权的权益。笔者结合黑龙江省实际，就这一问题谈几点认识与建议。  相似文献

Incorporation　of　Perception-based　Information　in　Robot　Learning　Using　Fuzzy　Reinforcement　Learning　Agents     

ZHOUChangjiu MENGQingchun GUOZhongwen QUWeifen YINBo 《青岛海洋大学学报(英文版)》2002,1(1):93-100

Robot learning in unstructured environments has been proved to be an extremely challenging problem, mainly because of many uncertainties always present in the real world. Human beings, on the other hand, seem to cope very well with uncertain and unpredictable environments, often relying on perception-based information. Furthermore, humans beings can also utilize perceptions to guide their learning on those parts of the perception-action space that are actually relevant to the task. Therefore, we conduct a research aimed at improving robot learning through the incorporation of both perceptionbased and measurement-based information. For this reason, a fuzzy reinforcement learning (FRL) agent is proposed in this paper. Based on a neural-fuzzy architecture, different kinds of information can be incorporated into the FRL agent to initialise its action network, critic network and evaluation feedback module so as to accelerate its learning. By making use of the global optimisation capability of GAs (genetic algorithms), a GA-based FRL (GAFRL) agent is presented to solve the local minima problem in traditional actor-critic reinforcement learning. On the other hand, with the prediction capability of the critic network, GAs can perform a more effective global search. Different GAFRL agents are constructed and verified by using the simulation model of a physical biped robot. The simulation analysis shows that the biped learning rate for dynamic balance can be improved by incorporating perception-based information on biped balancing and walking evaluation. The biped robot can find its application in ocean exploration, detection or sea rescue activity, as well as military maritimeac tivity.  相似文献
