后危机时代海南省城镇化发展的空间分异研究
The Spatial Difference study of Hainan’S urbanization development in The post-crisis era


- , 2017,
Abstract: 在后危机时代,明确海南省城镇化发展现状和趋势,对海南省因地制宜的选择城镇化和经济发展战略具有重要意义. 基于熵值法,从人口、社会、经济和地域景观等4个维度构建城镇化水平综合评价指标体系,对海南省2011—2013年18个市县的城镇化水平进行综合评价,并借助ARCGIS软件和空间自相关分析、抽样标准差的方法,对后危机时代海南省城镇化发展的空间分异进行探索,结果表明:(1)海南城镇化综合水平在逐年小幅度提升,但区域差异较大,形成明显“两极格局”和东、中、西线城市的城镇化水平递减格局;(2)空间自相关分析表明,海南省城镇化水平在空间分布上并没有表现出集聚的特征,不存在城镇化发展的核心带动区,且局部区域存在显著负相关关系;(3)城镇化类型区域差异明显,严重滞后、滞后、超前、严重超前型城市并存,积极型城镇化城市不多,且城镇化“双中心”城市城镇化均超前较严重,而积极型城市的城镇化和经济发展在省内均处于低水平.
:In the post-crisis era, clear status and trends of urbanization development in Hainan Province have great significance for the choice of local conditions of urbanization and economic development strategy. Therefore, using entropy method, four dimensions of urbanization comprehensive evaluation index system is built from the demographic, social, economic, geographical landscape, to evaluate the 18 counties of Hainan 2011-2013 urbanization level. In order to explore the spatial variation of urbanization development in Hainan Province in post-crisis era, the ARCGIS software and spatial auto-correlation analysis, the sample standard deviation of the method are used. The results show that (1) The comprehensive level of urbanization in Hainan province in recent years in the small amplitude increases year by year, but the regional difference is great, form "the bipolar structure", and the eastern city of urbanization level is high; (2) The spatial auto-correlation analysis shows that the regional urbanization level of Hainan province does not appear in the spatial distribution of the characteristics of similar value agglomeration, and there is a negative correlation relationship; (3) The regional differences in the types of urbanization are obvious, where coexistence of serious lag, lag, lead, lead, lead-based cities, and the "dual-core" cities of urbanization is leading ahead of economic development level, and cities which are positive type develop at a low level at urbanization and economic development

Abstract: 依据经济功能的分异将长株潭(长沙、株洲、湘潭)“3+5”城市群经济系统分解为生产子系统、流通子系统、分配子系统和消费子系统. 通过构建灰色系统熵、系统耦合度、耦合协调度以及序参量,对该城市群经济系统演化的时空分异特征及合理性进行刻画. 研究结果表明:(1)消费市场的发育与拓展主导推进长株潭“3+5”城市群经济系统持续有序演进;(2)交通网络的快速完善,推进了核心区乃至城市群整体的流通系统合理性发育,对于物流、人流突出的外围城市而言,则超出了其经济总系统的整体水平,产生负荷;(3)长株潭“3+5”城市群消费能力不足,但发展潜力较大.
: Based on the differences of economic function, the economic system of the Chang Zhu Tan “3+5” urban agglomeration is divided into the production subsystem, the circulation subsystem, the distribution subsystem and the consumption subsystem. On the basis of the related system entropy, coupling degree, coupling coordinative degree and order parameter, the spatio-temporal differentiations of the urban agglomeration’s economic system is depicted and the rationality of the system’s evolution is analyzed. The conclusions of the study are as follows. Firstly, the development and extension of the consumer market has played a dominant role in promoting the synergic development of the economic system of the Chang Zhu Tan “3+5” urban agglomeration. Secondly, the rapid improvement of transportation nets has strengthened the whole region’s negotiability. For the core cities, the circulation subsystem tends to rationalize, but for the peripheral cities, the development has increased their burden. Thirdly, the consumption of the urban agglomeration is a little weak, but its development potential is strong

地理研究 , 2011, DOI: 10.11821/yj2011050013
Abstract: 遵循国外对绿地价值的评价方向,借鉴国内外研究中的数据包络分析方法,对尚少涉足的城市绿地效率评价进行研究。构建城市公园绿地投入与环境效益产出的指标体系,评价2001~2008年广州城市公园绿地的生态效率。其中,公园绿地的环境效益产出主要用了绿地的固碳释氧、净化空气、调节气候和城市滞尘四大功能的生态价值估测方法,以此量化城市公园绿地环境效益的产出。结果显示(1)广州城市公园绿地的环境效益产出主要受土地和劳动影响,资本起辅助作用;(2)由于资本的投入冗余较高,广州城市公园绿地的生态效率现状偏低;(3)广州城市公园绿地生态效率经历了由2001~2004年的平稳优效期向2005~2008年的波动非优期的过渡;(4)规模效率对环境效益产出的贡献大于纯技术效率,园林绿化固定资产投资是影响纯技术效率的主要原因,公园绿地面积和职工人数是影响规模效率的主要原因。

Abstract: 满足乡村人口的心理需求是当下新农村建设的重要目标,从新市民群体中学生的“乡村依恋”切入提供了该研究的新视角。通过设计量表,运用Amos、Spss技术,对学生的乡村依恋特征、乡村认知特性进行探讨,并构建乡村特性与乡村依恋的结构方程模型,以寻求乡村依恋水平提高的举措,得出以下几点认识:(1)长期乡村生活成长的经历与体验赋予了乡村特殊的内涵与意义,乡村已成为新市民生命中不可分割的一部分,对乡村的情感认同成为学生乡村依恋的主要来源。(2)乡村特性与乡村依恋形成社会特性/物理特性—乡村依赖—乡村认同—乡村依恋的逻辑影响链,提高学生对乡村物理环境与社会环境的认同度有利于乡村依恋水平的提升,因此,在新农村建设中,应注重贯彻8字策略:“维护”乡村优越的物理环境,“完善”各项基础服务设施建设,“传承”优良的社会文化与风尚,对乡村生活安全、生产安全、生态安全进行制度化“管理”。(3)乡村社会特性对于新市民乡村依恋的构建具有更显著的影响,传承文化、安全管理、构建交往平台是新农村建设的最重要内容,新农村建设不应顾此失彼,与之背道而驰。
: In the background of current new rural construction facing with the contradictory of reality and the needs,It is essential to clear the present situation of rural and the demand of the rural population,the study of New citizens′ rural attachment provides a new perspective. By design scale, using Spss, Amos software,to explore the features of students′ rural attachment,the cognitive of rural characteristics,and then construct structural equation model about rural attachment and rural characteristics,in order to seek Measures of improve the level of rural attachment,The following conclusions are reached (1)The long-term experience of rural life and growth has gived special connotation and significance to rural village, rural have become an integral part of students' life, and the emotional identity also has become the major source of students' rural attachment. (2)Rural characteristics and rural attachment forms the logic chain of social characteristics / physical characteristics - country dependence - rural identity - rural attachment, Indicate,raising students' degree of identification of physical and social environment is conducive to enhancing the level of rural attachment, so,New rural construction should focus on the implementation of 8 words Strategies: "maintenance" superior physical environment in rural area, "consummate" the construction of service infrastructure, "inheritance" social culture, the implement of standardization management to rural life safety, production safety and ecological security. (3)The social characteristics of country has more significant influence to the construct of rural attachment, cultural heritage, safety management, communicate the platform of interpersonal communication are the most important content of new rural construction, The new rural construction should not care for this and lose that, draw further apart

华南师范大学学报(自然科学版) , 2014,
Abstract: 通过分析广州市2003-2012年产业结构与城市经济职能变动情况,并实证分析广州市生产性服务业发展与经济增长关系,发现(1)目前,第二产业对地区经济发展的拉动不强,第三产业对GDP的拉动作用长期稳定在较高水平,但劳动力就业结构适应慢于产业结构调整的速度,存在资源配置不合理的状况。(2)原来作为广州城市经济基础部门的工业和建筑业的地位下降,变为城市内部需要服务的产业,而服务业基本经济活动占有相当比重,而且有增长的趋势,已经发展成为基础性经济部门。(3)在工业化后期阶段,未来经济持续快速发展的动力将更加依赖于服务业的发展。但不同发展阶段对服务的需求不同,导致服务业结构随着经济社会发展不断演变,服务业内部从消费性服务业主导转向生产性服务业主导。

Abstract: 对小菜蛾Plutellaxylostella(L.)敏感品系、抗溴氰菊酯品系、抗杀虫双品系和抗杀螟丹品系的成虫脑突触体蛋白质磷酸化进行了研究比较。结果表明:蛋白质磷酸化在各个品系中的表现是不一样的。cAMP和钙加钙调蛋白对不同品系小菜蛾脑蛋白质磷酸化都有不同程度的刺激作用;3种杀虫剂均对各品系小菜蛾的磷酸化反应有影响,杀虫双、杀螟丹表现为抑制,溴氰菊酯表现为加强。这种影响在敏感品系中表现得比抗性品系中要强烈。

Abstract: 采用1984—2013年统计数据,运用协整分析和格兰杰因果检验对广州市房地产投资与经济增长关系进行分析,结果表明(1)房地产开发投资与GDP增长之间存在长期的均衡关系.房地产开发投资对GDP增长长期产生显著的正向促进作用;但在短期内,房地产开发投资对GDP的增长产生弱的反向影响.(2)格兰杰因果检验显示,在滞后2期时房地产开发投资对GDP存在单向的显著可信的Granger因果关系,反之则不成立.(3)脉冲响应分析显示,房地产开发投资对GDP产生持久的正向影响,且影响程度逐渐增强.

Abstract: 选取广州地铁3个代表性站点,基于实地调研与空间分析方法对比其商业集聚的共性与差异,并通过对商家的问卷调查分析其影响因素.研究发现地铁站周边商业网点以快速消费型为集聚主体,网点的空间分布不均,呈明显的圈层状结构,不同站点商业网点的集聚强度和共功能结构有所差别,可分为散布型、孤点型和聚合型等3种形态.商业属性、商家集聚效益和地铁的诱导是地铁站商业集聚呈现出共性的影响因素,依附商圈的发展差异、道路体系差异与地铁效应的差异是地铁商业集聚呈现差异的主要因素.
