江苏省河长制推行成效评价和时空差异研究

从水污染减排、水环境整治、水资源管理、水功能提升四个方面全面解读河长制推行的目标,在此基础上构建江苏省河长制推行成效评价体系,利用江苏省设区市2006-2015年的空间面板数据,系统分析江苏省河长制推行成果的现状和地区差异。研究发现,在河长制诞生的十年间,其推行成效经历了2010年以前的高速成长期、2011-2012年的波动成长期以及2013年至今的快速发展期;在空间层面,河长制推行成效水平呈现苏南、苏中、苏北递减的现象;而近三年江苏省区域间河长制推行成效水平的增长呈现出"北快南慢"的格局,河长制推行的空间差异逐渐缩小。建议今后进一步完善河长制考评和奖惩体系,加强水生态文明建设的技术研究和推广,并充分利用民间治水力量和资本,推进城乡河长制同步推广。

Evaluation and temporal-spatial differences of the effectiveness of the River Chief system in Jiangsu Province

This paper comprehensively interprets the targets of RCS (River Chief System) from four aspects, which are water pollution reduction, water environment improvement, water resources management, and water function improvement. On this basis, it builds the effectiveness evaluation system of RCS in Jiangsu. According to the spatial panel data of cities and districts in Jiangsu Province from 2006 to 2015, this paper systematically analyzes the present situation and regional differences of the implementation of RCS in Jiangsu Province. It is found that during the first decade since the RCS was implemented, its effectiveness has experienced a rapid growth period before 2010, a fluctuating growth period from 2011- 2012, and a rapid development period from 2013 to the present. At the spatial level, the effectiveness of the RCS tends to diminish from southern Jiangsu to middle Jiangsu and to northern Jiangsu. In the recent three years, the growth of effectiveness of RCS in Jiangsu Province is fast in the north and slow in the south, and the spatial difference has gradually narrowed. Finally, the paper puts fo rward the following suggestions: to improve the evaluation system as well as reward and punishment system of the RCS, to strengthen the research and promotion of the technologies of water ecological civilization construction, to promote the RCS in urban and rural areas simultaneo usly, and to make full use of civil forces and capital for water control.
