立足于黄河流域生态保护和高质量发展重大国家战略（以下简称“黄河国家战略”）实施与黄河河南段高质量发展需求，依据不同目的或研究需求，将黄河河南段空间研究范围划分为干流流经区、流域区、供水区、战略实施区以及全行政区；分析资源-生态-经济-社会复合系统耦合关系及多维目标任务，以目标为导向，以研究重点问题、核心技术、关键内容为主体，构建高质量发展路径优选研究框架；剖析亟待解决的4个重点问题和亟待突破的3个核心技术，从4个方面详细论述路径优选研究关键内容，并初步构想对应研究思路。研究成果不仅可以指导黄河流域区域尺度高质量发展路径优选，而且可以应用于其他区域高质量发展研究和路径优选实践。

Highquality development of the Yellow River basin is the main goal and task for Yellow River′s national strategy.The Henan section of the Yellow River is a key economic and cultural zone in the Yellow River basin (YRB).To clarify the spatial research scope in the Henan section of the Yellow River and conduct indepth research on the optimization of highquality development paths is of great strategic significance for the future growth of Henan Province and YRB. To clarify and define the research scope of the Henan section of the Yellow River and provide basic support for subsequent research work,the spatial research scope is divided into five subregions based on different research needs,namely: mainstream flow area,drainage area,water supply area,strategic implementation area,and all administrative regions.The mainstream flow area in the Henan section of the Yellow River refers to the area composed of all the municipal administrative districts in Henan Province that flow through the mainstream of the Yellow River,with a total area of 57,900 km2.The drainage area of the Henan section is 36,200 km2 within the jurisdiction of Henan Province.The water supply area is 104,000 km2 of the Henan section of the Yellow River,which refers to the area composed of all municipal administrative districts that use Yellow River water as a water supply source in Henan Province.The strategic implementation area in the Henan section refers to all municipallevel administrative areas affected by the Yellow River national strategy within Henan Province,covering 15 cities with a total area of 106,600 km2.Based on this zoning,15 cities in Henan Province are included in the Yellow River national strategy,and Nanyang,Xinyang,and Zhumadian are included in the development strategy of Yangtze River economic belt strategy.All administrative regions refer to all municipallevel administrative regions throughout Henan Province,iIncluding 18 cities in the province,with a total area of 167,000 km2. Based on an indepth understanding of highquality development,under the guidance of important ideas such as sustainable development,harmony between humans and water,and ecological civilization,a research framework for selecting highquality development paths for the Henan section of the Yellow River is constructed.[JP2]The tasks that need to be achieved to research the optimization of highquality development paths include safe supply of resources,ecological health and livability,orderly[JP] economic growth,social harmony and stability,and advanced cultural leadership.The key issues that need to be resolved include ①resourcesecologyeconomysociety harmonious balance theory and quantification; ②identification of key constraints on highquality development; ③optimization method for highquality development paths based on harmonious balance theory; ④construction of a harmonious regulation model for highquality development.The core technologies that need to be broken through include: ① Identification technology for the key constraints of highquality development of the resourceecologicaleconomicsocial composite system development; ②dynamic simulationoptimization technology for the optimization of highquality development path;③highquality development of multidimensional critical harmony control technology based on the harmonious balance theory. Four key contents of the research on the optimization of highquality development paths include: (1) resourceecologicaleconomicsocial composite system harmonious balance theory and quantitative research methods,including: ①the harmonious balance relationship between highquality development and resourceecologicaleconomicsocial;②resourceecologicaleconomicsocial harmonious balance model and theoretical framework system;③harmonious balance theory application rules and plan formulation cycle path method; ④harmonious balance discrimination criterion and quantitative evaluation method.(2) Identification of key constraints and countermeasures for highquality development of the Henan section of the Yellow River,including: ①analysis of the mutual feedback relationship between resourceecologicaleconomicsocial composite system;②identification of key factors restricting the highquality development based on system identification technology;③responding strategies for key constraints on highquality development under changing circumstances.(3) highquality development path selection and strategic layout in the Henan section of the Yellow River based on the harmonious balance theory,including:①analysis of the highquality development path; ②optimization of highquality development paths based on the harmonious balance theory; ③highquality development strategy layout.(4) the highquality development harmonious regulation model and application of the Henan section of the Yellow River,including: ①guidelines and indicators for the harmonious regulation of highquality development;②highquality development resourceecologicaleconomicsocial harmony goal and quantification; ③construction,application test and effect evaluation of highquality development regulation model.
