摘要
基于对稳定性的认识和理解,以压力、敏感性和响应等稳定性要素构建流域经济系统稳定性评价指标体系和评价模型,对松花江(吉林省段)流域经济系统稳定性演变特征进行分析。结果如下。1)从压力得分来看,松花江(吉林省段)流域经济系统压力具有显著的空间分异特征。2)从敏感性得分来看,流域内吉林市、松原市和白城市自身经济系统内部结构和功能不尽合理,一定程度说明松花江(吉林省段)流域的经济结构合理性较差。3)从响应得分来看,松花江(吉林省段)流域经济系统响应总体呈现出由流域自上而下依次降低的特征。4)从稳定性得分来看,松花江(吉林省段)流域经济系统稳定性具有明显的中心-外围特征,并且区域间差异程度不断扩大,尤其是长春市和白城市之间。今后经济发展过程不仅要巩固流域核心城市的优势地位,更要加快流域边缘城市的发展,注重经济发展的质量和效率,避免差距进一步扩大。
Based on the knowledge and understanding of stability, this paper establishes an evaluation index system and an evaluation model of stability of basin economic system from the aspects of stability elements such as pressure,sensitivity,and system response,and analyzes the stability evolution characteristics of basin economic system of Songhua River in Jilin province. The results are given as follows. Firstly,the pressure of basin economic system of Songhua River in Jilin Province has obvious spatial differentiation characteristics. Secondly,the internal structures and functions of economic systems in Jilin city,Songyuan city,and Baicheng city are not reasonable,which implies low level of economic structure of the Songhua River basin in Jilin Province. Thirdly, the response of basin economic system of Songhua River in Jilin Province shows a feature of gradually decreasing from upstream to downstream.Finally,the stability of basin economic system of Songhua River in Jilin Province shows a center-periphery feature,and the differences between the regions are constantly expanding,especially the difference between Changchun city and Baicheng city.It will be very important for the process of economic development in future to consolidate the dominant position of the core cities in the basin,accelerate the economic development of the marginal cities in the basin,pay attention to the quality and efficiency of economic development,and avoid further widening the gap.
