Abstract

Abstract

Taking the typical small and medium-sized rivers of the plain river network area in Jiashan County of Zhejiang Province as the study area, the water quality index (WQI) method was used for water quality assessment, according to monthly monitoring data of fourteen sections from 2015 to 2020. On this basis, the spatio-temporal variation characteristics of the water quality were explored using the Mann-Kendall (M-K) trend test combined with geographic information system (GIS). The results indicated that the average WQI value was 65.09 in the five years, showing the evaluation level of "medium". The water quality of rivers had obvious spatio-temporal differences i. e., water quality was improved gradually from 2015 to 2020, superior in non-flood season to flood season within intra-annual variation and better in the northern area compared to southern. The main influencing factors of spatio-temporal differences in water quality were precipitation, human activity and land use types. These results would provide critical information for the management of water resources.
