行政建置变更对海南岛区域文化历史发展的影响研究   总被引:2,自引:1,他引:1  
朱竑  司徒尚纪 《地理科学》2006,26(4):490-496
一个区域文化的发展除了受历史时期科技发展水平、移民、国家开拓方略等因素的影响外,也因为行政建置的不同而产生很大的不同。不少地方因为长期隶属于同一个行政区,在文化上就表现出非常明显的趋同性。而历史期海南岛区域文化的发展进度则与反映中央王朝重视程度的行政建置的级别、深入岛内实质管理的辖区大小等要素紧密相关。行政建置变更某种程度上已经成为海南岛历史文化发展进程中重要的导向标。在探讨了历史期海南岛行政建置变更对海南岛文化发展带来的影响,以期对海南岛区域文化的生成和发展寻求上层建筑方面的依据。  相似文献

By means of setting up experimental spots of the influences of four representative crop_planting types—maize,potato,soybean and maize_soybean intercrop on rainfall erosion,and measuring continuously three years in the northeast mountain region of Yunnan province,the C value of crop_planting factor was analysed and calculated.The results showed1.the conserving effect of crops on the soil of slopeland increases with the growth of crops,i.e.the higher the covering rate of ground is,the lower the C value is.2.in four crop_planting types,the maximum conserving effect on the soil of slopeland is maize_soybean intercrop,its C value is 0.1990,the C values of other crops are respectivelymaize 0.3517,soybean 0.3551,potato 0.3721.  相似文献

"The value of the world's ecosystem services and natural capital" by R.Costanza et al.in 1997 is generally regarded as a monument to the research of valuing ecosystem services.However,the classification of ecosystem services,the method of various services summation,and the purpose for static global value had many criticisms.Based on a summary of these criticisms and suggestions,further study direction—on the sustainability of ecosystem services—is presented.The two basis indicators in ecology—productivity and biodiversity,respectively characterize the ability of producing and self-organizing—not only represent the internal function of ecosystem,but also can be proportioned to its external function of supporting and providing for human life.Theoretically,the two indicators combined could physically assess the sustainability of ecosystem services based on the traditional procedure of Costanza's.The case study of Hohhot City in 1995-2005 shows that the new model reflects the changes of ecosystem services at spatial and temporal scale,and the functionally adjusted assessment shows the sustainability of Hohhot City became gradually stronger during the study decade.But due to the enormous value per unit of water ecosystem,the minimal loss of water area leads to the final result being opposite to the processing analysis,which gives a clue to the further experimental testing research.  相似文献

Air pollution is a serious problem brought by the rapid urbanization and economic development in China, imposing great challenges and threats to population health and the sustainability of the society. Based on the real-time air quality monitoring data obtained for each Chinese city from 2013 to 2014, the spatiotemporal characteristics of air pollution are analyzed using various exploratory spatial data analysis tools. With spatial econometric models, this paper further quantifies the influences of socioeconomic factors on air quality at both the national and regional scales. The results are as follows:(1) From 2013 to 2014, the percentage of days compliance of urban air quality increased but air pollution deteriorated and the worsening situation in regions with poor air quality became more obvious.(2) Changes of air quality show a clear temporal coupling with regional socioeconomic activities, basically "relatively poor at daytime and relatively good at night".(3) Urban air pollution shows a spatial pattern of "heavy in the east and light in the west, and heavy in the north and light in the south".(4) The overall extent and distribution of regional urban air pollution have clearly different characteristics. The formation and evolution of regional air pollution can be basically induced as "the pollution of key cities is aggravated—pollution of those cities spreads— regional overall pollution is aggravated—the key cities lead in pollution governance—regional pollution joint prevention and control is implemented—regional overall pollution is reduced".(5) At the national level, energy consumption, industrialization and technological progress are the major factors in the worsening of urban air quality, economic development is a significant driver for the improvement of that quality.(6) Influenced by resources, environment and the development stage, the socioeconomic factors had strongly variable impacts on air quality, in both direction and intensity in different regions. Based on the conclusion, the regional differentiation and development idea of the relationship between economic development and environmental changes in China are discussed.  相似文献

The implementation of the Belt and Road Initiative and the increasing frequency of the China-Europe Railway Express(CER Express) have brought new improvement to the production system of enterprises along the Belt and Road regions. On the basis of summarizing the evolution of production system of enterprises, this paper takes TCL Poland Plant as an example to conduct an in-depth study on the characteristics of the plant's current production system and its differences from the original production system, and analyzes the impact of the CER Express on its current production system. Some conclusions can be drawn as follows.(1) CER Express had a great impact on the production system of TCL Poland Plant, which is mainly manifested in the following aspects. First, the transport of raw materials by CER Express improves the time efficiency and shortens the whole supply chain. Second, CER Express acts as a "moving inventory", which realizes the flexibility of raw material inventory and "zero inventory" effect based on the punctual transport. Third, the time and inventory effects brought by CER Express speed up the response to European market. The comprehensive benefits brought by CER Express lead to a more punctual and lean production system, meet the diversified needs of consumers on account of product quality and diversification, and improve ability to expand European market.(2) On the basis of abandoning the original "Rigid Mass Production" system, we argue that TCL Poland Plant formed a unique production system—"Global Fluid Just-in-Time" which absorbed the essence of Toyota Production System based on the punctual transnational transportation of CER Express.(3) The differences between the current and the original production systems of TCL Poland Plant are mainly focused on the following aspects: the difference of transport and storage mode of raw materials, and the changes of production line, production mode and quality inspection organization, etc.  相似文献
