北京山区沟域经济发展的空间结构 总被引:1,自引:0,他引:1
Valley economy is a new mode in mountainous area development that is defined by various characters of valley development, and is a distinguishing economical geographic pattern for mountainous area development. The special spatial coupling relations in the distribution of different mountainous elements in valleys are new subjects for the mountain development studies, and such studies are meaningful both for researches and practices. Based on the long term researches on mountainous area development and following a brief exploration into the connotations and the spatial organizing process of valley economy, the authors analyzed the present situations of the development of valley economy in Beijing’s mountainous areas, studied the characteristics and the impacts of the spatial structural changes of the valley economy in Beijing’s mountainous areas, and finally proposed a rational arrangement of the spatial structure of the valley economy in Beijing’s mountainous areas. It is considered in this study that valley economy plays an important role in the development and functional transformation in Beijing’s mountainous areas in the new epoch. Firstly, valley economy is not outlined by the administrative boundaries, and it connects most of the villages in the mountainous areas roughly along the major transportation lines. Therefore, valley economy can exert positive influence on the development in the mountainous areas, at least in the aspects such as the rearrangement of industrial structure in the mountainous areas and the coordinated development of rural and urban areas. In addition, it is found that the valley economy in Beijing’s mountainous areas is evolved in a spatial organizing stage of secondary concentration, which is characterized by resource-saving, ecological protection and industrial optimization. Therefore, the development of valley economy will be helpful to the coordination between ecological protection and economic development in the mountainous areas, and will promote the integrated development of the mountainous areas. The developing mode of the valley economy in Beijing’s mountainous areas will provide the basis for the decision-making in the transformation of the functional roles of Beijing’s mountainous areas, and on the other hand, will present experiences for the studies in the mountainous areas outside of Beijing. 相似文献

北京作为全国的政治、经济、文化中心,具有强大的综合创新优势,必须在实现经济体系高效性与生态系统稳定性上做出表率,建设首都生态经济区是北京山区科学发展的必然趋势。首都生态经济区地域范围为北京的七山区县,其建设要以"两山、五河、七组团"为空间结构,以"一区、三基地、一平台"为框架性目标。作为探索北京山区环境、经济与社会协调发展的路径,建设首都生态经济区是优化山区生态环境建设的现实需要,符合山区发展转型的客观要求,具有重要的科学意义、实践基础和理论依据,应遵循打破行政界限、生态主导发展等原则,力争用10-15年的时间,建设生态产业经济带(走廊)、拓展生态经济区地域空间范围、打造中国北部生态经济增长极,以建设成北京绿色崛起先导区和全国生态经济示范区。 相似文献

生态城市建设背景下湛江红树林的保护与利用 总被引:3,自引:1,他引:2
以中国最大的红树林生长基地———湛江市为例,经过实地调研和多方论证,分析了当前湛江红树林的生存现状和存在的问题。究其原因在于:对红树林在区域生态安全格局中的战略意义认识不足、当地社会经济发展带来的巨大冲击,以及红树林资源开发的滞后等。针对这些问题,首先从海陆一体化、海岸带等方面,明确了红树林湿地在维护区域生态安全格局中的战略地位。在此基础上,厘清了红树林湿地在湛江生态城市建设中的意义和作用,提出了今后湛江红树林湿地的总体建设方向:(1)以红树林湿地为核心,重构湛江市的区域生态安全格局;(2)加强湛江市红树林生态系统的重构;(3)开展沿海红树林的生态恢复;(4)推进生态旅游产业的开发。 相似文献

中国东部沿海城市旅游发展的时空演变 总被引:1,自引:0,他引:1
城市旅游时空演变是旅游地理学研究的热点领域。以中国东部沿海城市为研究区,分析城市旅游发展的时空演变格局。首先分析沿海城市旅游发展强度的时空演变,进而采用DEA数据包络分析法计算沿海城市旅游发展效率的时空演变。研究表明:① 在旅游发展强度方面,东部沿海城市之间的旅游发展强度差异较大,长三角、珠三角以及环渤海的辽东半岛和山东半岛地区的旅游发展强度较强,海峡西岸经济区和环北部湾地区的旅游发展强度较弱。② 10年间在旅游发展综合效率方面基本维持不变,而旅游发展纯技术效率显著增强,旅游发展的规模效率则显著减弱。说明沿海城市的旅游发展已经逐渐由规模效率向技术效率转变。③ 综合旅游发展强度和旅游发展效率两个方面看,将东部沿海城市旅游发展类型分为“高—有效型”、“低—有效型”、“高—无效型”和“低—无效型”四种类型。其中“高—有效型”城市旅游发展较为成熟,“低—有效型”和“高—无效型”城市旅游发展一般,“低—无效”城市旅游发展相对较差。整体来看,珠三角和海峡西岸地区旅游发展强度和旅游发展效率均出现一定程度下滑,长三角、环渤海和北部湾地区的旅游发展强度和旅游发展效率均呈现不同程度增加。 相似文献

海岛是一个特殊的地域单元,拥有其特有的发展模式和路径,近年来随着海洋国土地位的提升,国内外学者对于海岛的研究也随之增多。本文以我国海岛县域经济体为研究对象,从分析我国海岛县域经济体产业结构入手,采用产业变动系数法和偏离份额分析方法对海岛县域经济的演进以及竞争力进行了研究,研究发现:海岛县产业结构演进是左旋和右旋的结合演进模式,海岛县产业结构相对单一,产业结构演进的跳跃性特征明显。根据海岛经济发展水平分析,将12个海岛县的经济发展分为竞争增强结构优化型、竞争增强结构衰退型、竞争减弱结构优化型、竞争减弱结构衰退型、结构相对稳定型5种类型。 相似文献

社会生态补偿标准测算方法(英文) 总被引:2,自引:0,他引:2
Ecological compensation is a hot subject in academic studies, and the determina-tion of the spatial allocation of compensation payments is a key point in the research of eco-logical compensation. There are two kinds of thoughts in the determination of regional spatial allocation at present: "evaluation of ecological construction cost" and "evaluation of ecosystem services value". This paper analyzes the relationships between social ecological compensation and regional socio-economic development, and establishes two econometric models with the data of 2007 from various provinces in China. Through these models, the impacts of geographical endowments on the regional socio-economic development in various provinces are analyzed from the social justice viewpoint and the concept of "equivalent value of geographical endowments" (EGE for short) is proposed. This paper analyzes the application prospect of EGE in the policy making of regional ecological compensation. The results showed that: (1) the implementation of social ecological compensation is not only an effective guarantee for each region to obtain the equal rights of survival, development and decent environment, but also an essential assurance to the coordinated, balanced and sustainable development among various regions; (2) the regional difference in geographical endowments is an important factor affecting the regional spatial variation of socio-economic development. Therefore, geographical endowments are important bases for the determination of the spatial allocation of compensation payments in social ecological compensation; (3) based on the EGE, the government can determine the spatial allocation of social ecological compensation scientifically, and avoid the "sweeping approach" phenomenon in the policy making process of ecological compensation. 相似文献
