湖南长江经济带人水关系协调与城镇化耦合协调机制研究

指出了中国已经步入了以提高城镇化质量为核心的新型城镇化时代,在新型城镇化发展的过程中,生态文明建设的地位越来越突出。位于长江沿岸的湖南长江经济带,其人文和水环境的协调度与新型城镇化发展之间的关系越来越紧密。以湖南长江经济带的岳阳沿江地区为研究区域,利用灰色关联度模型建立了评价人水关系协调与城镇化耦合协调度的指标体系,再利用耦合协调度模型探索了2008~2017岳阳沿江地区人水关系协调与城镇化的耦合协调机制。

水利建设可持续发展刍议

首先分析了水利建设与可持续发展的关系,即可持续发展对水利建设提出了新要求、丰富了新思路,水利建设实践推动了水利可持续发展研究,并基于此提出水利建设可持续发展思路,即树立可持续发展意识,推进水利建设制度创新;人水协调,加强水利现代化建设。

岳阳市现代水利体系建设研究

地处湘东北的岳阳正积极融入对接长江经济带、长江中游城市群、洞庭湖生态经济区等国家战略,中共湖南省委将岳阳列为该省通江达海的新增长极,对岳阳的水利改革发展提出了更高要求。岳阳应从水利改革发展的体制机制、保障措施等方面着手,全面推进人水协调现代水利体系建设,为经济社会发展提供防洪安全、生态安全、供水安全保障。

治江新理念在长江流域防洪规划中的运用

防洪减灾的实践表明,要完全消除洪水灾害是不可能的,从长远发展和全局利益考虑,既要适当地控制洪水,改造自然,又要顺应客观规律,主动地适应洪水,做到人与洪水协调共处。依照新完成的长江流域防洪规划的成果,简述长江防洪减灾面临的形势,结合治江新理念对长江防洪提出的新要求,简述了人水协调治水思路在长江流域防洪规划中的具体运用,即建立人水协调的综合防洪减灾体系,将“平垸行洪、退田还湖”纳入长江防洪体系,拟定合适的堤防级别、设计水位和堤顶超高,调整分蓄洪区的类别和建设思路,更加重视防洪非工程措施。

Coupling Coordination Relationship between Ecological Human Settlements and the Happiness Levels of Residents in the Yangtze River Delta Urban Agglomeration

Promoting the coordinated development of ecological human settlements and the happiness levels of residents will help to promote people-centered high-quality development.This study was based on the 2011-2021 data of the Yangtze River Delta urban agglomeration,and constructed an evaluation index system of ecological human settlements and the happiness levels of residents.The entropy value method,coupling coordination degree model,Dagum Gini coefficient and Geodetector model were used to explore the coupling coordination relationship and influencing factors of these two systems.The findings indicate that ecological human settlements and the happiness levels of residents in the Yangtze River Delta urban agglomeration have shown an upward trend over time.By 2021,the overall level of the region had significantly improved.The coupling coordination level between these two systems has gradually increased,showing a spatial distribution pattern of high in the east and low in the west.The Dagum Gini coefficient shows a fluctuating downward trend in the overall and intra-regional differences,with the largest inter-regional difference between Shanghai and Anhui,and the inter-regional difference is the main source of the spatial differences.Economic development level(Eco)was the main factor influencing the coupling coordination of the two systems from 2011 to 2021.The results of this study provide references for constructing ecological human settlements and enhancing the happiness levels of residents.
