CHARACTERISTICS OF ZONAL ANOMALY OF ANNUAL PRECIPITATION IN THE NORTHEASTERN CHINA     

YANMin-hua DENGWei CHENPan-qin LIANGLi-qiao 《中国地理科学(英文版)》2004,14(4):320-325

The characteristics of zonal anomaly and change rule of temporal distribution of annual precipitation in the northeastern China are revealed in this paper with EOF (Empirical Orthogonal Function) and REOF (Rotated Empirical Orthogonal Function) methods and results are drawn in the standard relief maps with GIS technology for practical application. Data used in the study were obtained from 208 meteorological stations over the northeastern China from 1961 to 2001. EOF results show that the first 3 loading vectors could give entire spatial anomaly structure of annual precipitation. In the Northeast Plain including the Songneng Plain and the Liaohe Plain, there is a regional compatibility (whether wet or dry) of annual precipitation change and this precipitation pattern has occurred since the late 1980s to the present. There also exist annual precipitation patterns of wet (or dry) in south and dry (or wet) in north and wet (or dry) in east and dry (or wet) in west. REOF results display 8 principal precipitation anomaly areas by the first 8 rotated loading vectors: the west plain, the Liaodong hills, the Sanjiang Plain, the Liaoxi hills,the Changbai Mountains, the Hulun Buir Plateau, the southwest plateau and the Liaodong Peninsula.  相似文献

运用钱纳里工业阶段论与钱纳里和塞尔昆的多国模型对城市化状态与产业结构的验证表明,渝东北总体还处于初级产品生产阶段,只能定位于组团式城市群之间的次增长极。结合城乡统筹必要性与国际经验,发现培育产业集群是渝东北次增长极破解产业空虚与实现城乡统筹的最优路径。  相似文献   

Decomposition analysis on direct material input and dematerialization of mining cities in Northeast China     

Fangdao Qiu  Lianjun Tong  Huimin Zhang  Na Zhang 《中国地理科学(英文版)》2009,19(2):104-112

Material dematerialization is a basic approach to reduce the pressure on the resources and environment and to realize the sustainable development. The material flow analysis and decomposition method are used to calculate the direct material input (DMI) of 14 typical mining cities in Northeast China in 1995-2004 and to analyze the demateri-alization and its driving factors in the different types of mining cities oriented by coal, petroleum, metallurgy and multi-resources. The results are as follows: 1) from 1995 to 2006, the increase rates of the DMI and the material input intensity of mining cities declined following the order of multi-resources, metallurgy, coal, and petroleum cities, and the material utilizing efficiency did following the order of petroleum, coal, metallurgy, and multi-resources cities; 2) during the research period, all the kinds of mining cities were in the situation of weak sustainable development in most years; 3) the pressure on resources and environment in the multi-resources cities was the most serious; 4) the petro-leum cities showed the strong trend of sustainable development; and 5) in recent years, the driving function of eco-nomic development for material consuming has continuously strengthened and the controlling function of material utilizing efficiency for it has weakened. The key approaches to promote the development of circular economy of min-ing cities in Northeast China are put forward in the following aspects: 1) to strengthen the research and development of the technique of resources' cycling utilization, 2) to improve the utilizing efficiency of resources, and 3) to carry out the auditing system of resources utilization.  相似文献   

Comprehensive evaluation on urban sustainable development of Harbin City in Northeast China   总被引：1，自引：1，他引：0  

Chunmiao Cai  Jincheng Shang 《中国地理科学(英文版)》2009,19(2):144-150

It is an effective way in realizing urban coordinated and sustainable development to establish a series of indicators and to evaluate urban environmental and socioeconomic development. According to the characteristics of Harbin City in Northeast China, an indicator system including five subsystems and 37 indicators was established for comprehensive evaluation on urban sustainable development. The development indexes of all urban subsystems and complex system were calculated quantitatively using the comprehensively integrated methods composed of Principle Component Analysis, Analytic Hierarchy Process and weighed index method, and then the comprehensive level of urban sustainable development and the degree of urban interior coordination were analyzed. The results indicated that 1) the overall urban development presented an uptrend, however, the interior development was not well balanced from 1996 to 2006; 2) the development in each subsystem presented a strong fluctuation; and 3) the development in resources subsystem showed a downtrend. Based on those results, the suggestions of urban sustainable development were put forward at the end.  相似文献

东北三省城乡收入差距空间格局及其分异机制研究   总被引：2，自引：4，他引：2  

付占辉  梅林  刘艳军  郑茹敏 《地理科学》2019,39(9):1473-1483

借助多元逐步线性回归、GWR等模型方法,探讨1990年以来东北三省城乡收入差距空间格局、类型特征及其分异机制,最后提出城乡统筹可持续发展建议。结果表明： 1990年以来,东北三省城乡居民收入水平大幅提高,但大部分地区城镇居民可支配收入水平仍低于全国平均水平;城乡收入差距整体有所拉大,呈现出“中间高、两端低”的空间特征。 城乡收入差距空间分布格局受经济发展水平、工业拉动效应、服务业带动力和交通通达程度影响,其中经济发展水平对城乡收入差距由早期的正向拉大作用为主,逐步演变为负向抑制效应。 据此提出对策建议：深化改革开放,加快国有企业改革步伐,优化区域产业结构,提高服务业发展水平和比重,激发市场活力,破解制约区域经济发展的各种障碍;加快实施乡村振兴战略,促进乡村资源开发,开辟致富增收新路径。  相似文献
