摘要
采用地理加权回归方法构建长江水质与各潜在影响因素关系模型,定量化各影响因素对水质的影响强度,并探索港口设施、工业和农耕活动对长江水质的潜在影响及影响程度的空间差异。结果表明,2017—2021年间,长江(安徽)经济带“1515”范围内水环境监测指标变化全面向好,初步实现“水清”建设发展目标,并在研究成果的基础上提出岸线水质保护工作的对策建议。
It uses geographic weighted regression method to construct a relationship model between the water quality of the Yangtze River and various potential influencing factors,quantifying the impact intensity of each influencing factor on water quality,and exploring the potential impact and spatial differences of port facilities,industrial and agricultural activities on the water quality of the Yangtze River.The results show that from 2017 to 2021,the changes in water environment monitoring indicators within the“1515”area of the Yangtze River(Anhui)Economic Belt have comprehensively improved,and the development goal of“water purification”construction has been preliminarily achieved.Based on the research results,countermeasures and suggestions for shoreline water quality protection work have been proposed.
