区域一体化研究综述：尺度、联系与边界

区域一体化是当今世界最具活力的经济现象之一,它是一个多维度的空间现象,也是一个多学科参与的科学问题。地理学独特的尺度、联系和边界视角对于理解区域一体化是如何改变世界经济格局及其对国家和区域发展的影响有重要意义。文章梳理了区域一体化理论和发展,以尺度、联系和边界的分析视角重新审视了快速发展的区域一体化进程,阐述了区域一体化的网络化特征和多维联系,重新定义了区域一体化中的多重边界,并从“全球―地方”联系的角度对区域一体化进程下有关区域和地方发展的研究进行了综述。区域一体化的实践表现出越来越多的网络特征,形成了以国家权力和关系为导向,涵盖多维度邻近的立体网络空间;区域一体化的边界效应重塑了全球经济格局,同时传统的领土边界依然重要;区域一体化的制度安排深刻影响了一国边境地区的发展和经济地理格局。最后,针对区域一体化,从尺度建构、内部联系、边界效应和多元分析框架等角度指出了亟待学界解决的一些问题,并展望了未来的研究趋势。

中国主体功能区划的科学基础

Major function oriented zoning (MFOZ hereafter) is the guideline for optimizing the spatial pattern of regional development in China, which entails both theoretical and methodological innovation in the academic field of economic geography. This study analyzes the basic features of territorial function and puts forward a spatial equilibrium model for regional development for the first time. It argues that there exists a trend of regional convergence in the average value which indicates the comprehensive development status of any region. Based on this finding, the study illustrates that the formation of functional zone should be conducive to the narrowing of regional gap and that free flow of resources between regions is the prerequisite to spatial equilibrium. It also investigates the impact of territorial functional evolution on the process of spatial equilibrium and suggests that the maximization of benefits derived from zoning proposal is interrelative with the method of regional division and the degree of understanding towards the temporal changes of territorial function. Furthermore, this study goes on to examine the scientific foundation of several issues concerning the reconciliation between contradictory functions of development and protection, the selection of indicators and the spatial and temporal features of MFOZ. It is then probes into the rationality of achieving dual goals of efficiency and equality simultaneously through three-dimensional flow and spatial equilibrium. The paper ends with discussions on the position, implementation and coordination of MFOZ from the perspective of institutional arrangements of spatial governance including law, planning and government policy.     

Decadal Climatic Anomalies in the Northern Adriatic Sea Inferred from a New Oceanographic Data Set

Abstract. In 1997, Artegiani et al. depicted for the first time the seasonal climatology of the Adriatic Sea; they used the ATOS data set, formed by 5540 oceanographic stations sampled over this continental basin from 1911 to 1980. Lately, two Italian institutes working on the Adriatic Sea for long time, IBM and IRPEM, merged their recent data sets for the northernmost part of the basin. This yielded 3600 new oceanographic stations, concentrated in an area where 809 ATOS stations were located. The new data were quality checked, and then a seasonal climatology was drawn up as a first analysis step. The new climatology differed significantly from the ATOS results; this could be explained, at least partially, by the climatic changes that have occurred on this area. For example, air temperature increased significantly over northern Italy starting from 1988. Variations of the observed air temperature and Po River runoff qualitatively agree with sea surface temperature and salinity variations. A preliminary computation of heat fluxes based on ECMWF reanalysis confirms an increased heat flux to the Northern Adriatic Sea starting from 1988.     

一种区域自适应的遥感影像分水岭分割算法

提出了一种区域自适应的标记分水岭分割方法。该方法利用高斯低通滤波和概率统计相结合的方法,对梯度影像进行区域自适应阈值分割,提取分割标记,然后采用Meyer算法进行标记分水岭分割。实验结果表明,该算法能够有效解决遥感影像不同区域的分割问题,达到比较理想的水平。     

中国城市人力资本水平与人口集聚对创新产出的影响

基于中国2007—2012年287个地级及以上城市的创新投入要素和专利申请量的面板数据（未含港澳台地区数据）,采用面板固定效应模型和面板分位数回归模型,揭示人力资本水平提升对区域创新产出的影响机制及其区域异质性,以及人口空间集聚对人才创新驱动作用的调节机制。结果表明：① 平均而言,人力资本水平越高的城市,创新产出水平越高,但人口集聚程度与创新产出水平并不存在显著的关联;② 人力资本水平提升对创新的驱动作用存在区域差异,在创新等级越低的城市中其作用效果越强;③ 人口空间集聚强化了人力资本水平对创新的驱动作用,城市规模扩大促进了知识的溢出;④ 人口空间集聚调节作用的显现需要达到一定的创新基础门槛,城市创新等级越高,调节作用越强。因此,各地方政府应当结合当地发展的实际情况,制定适宜的人才培育和人才引进策略,合理引导人才流动。     

Projected Climate Change in the Northwestern Arid Regions of China: An Ensemble of Regional Climate Model Simulations

The projected temperature and precipitationchange under different emissions scenarios using Coupled Model Intercomparison Project Phase 5 models over the northwestern arid regions of China(NWAC) were analyzed using the ensemble of three high-resolution dynamical downscaling simulations: the simulation of the Regional Climate Model version 4.0(Reg CM4) forced by the Beijing Climate Center Climate System Model version 1.1(BCC_CSM1.1); the Hadley Centre Global Environmental Model version 3 regional climate model(Had GEM3-RA) forced by the Atmosphere-Ocean coupled Had GEM version 2(Had GEM2-AO); and the Weather Research and Forecasting(WRF) model forced by the Norwegian community Earth System Model(Nor ESM1-M). Model validation indicated that the multimodel simulations reproduce the spatial and temporal distribution of temperature and precipitation well. The temperature is projected to increase over NWAC under both the 4.5 and 8.5 Representative Concentration Pathways scenarios(RCP4.5 and RCP8.5, respectively) in the middle of the 21 st century, but the warming trend is larger under the RCP8.5 scenario. Precipitation shows a significant increasing trend in spring and winter under both RCP4.5 and RCP8.5; but in summer, precipitation is projected to decrease in the Tarim Basin and Junggar Basin. The regional averaged temperature and precipitation show increasing trends in the future over NWAC; meanwhile, the large variability of the winter mean temperature and precipitation may induce more extreme cold events and intense snowfall events in these regions in the future.     

Debates about the pre-Variscan tectonics of Poland

Summary The tectonic nature of the deformed Early Palaeozoic belt along the southwestern border of the East European Craton (EEC) has long been debated. The essence of these debates is reviewed and the recently published map of the Variscan tectonics in Poland is discussed from methodological and regional points of view. The terrane origin of the Pomeranian and ysogóry regions is questioned; they are inferred to be parts of the passive margin of the EEC (miogeocline), deformed into a marginal fold-and-thrust belt. The Maopolska Block and especially the Upper Silesian Block could be Caledonian (proximal?) terranes.     

基于ESDA的区域经济空间差异分析——以江苏省为例

基于ESDA全局和局部空间自相关分析,利用江苏省1978～2002年县域人均GDP数据,对江苏省县域总体和局部空间差异的变化趋势、特征与成因进行了初步探索。结果首先表明,随着我国改革开放进程的逐步深化,江苏省县域经济空间差异在总体上呈现缩小趋势。其次,江苏省县域局部空间差异不断缩小,特别是苏南和苏北县域,表现出与周边地区同步发展态势。再者,苏南地区对全省的极化效应明显大于其扩散效应。大致自1992年以来,苏南和苏北地区内部分别形成了与周边地区显著相似的区域。最后,江苏省县域总体和局部空间差异的缩小并不是全省区域经济协调发展的标志,而是南北空间分异的表现。在循环累积因果机制作用下,南北差异有可能进一步扩大。
