Impact of Rapid Urbanization on Shenzhen Water Environment
Published 2023-01-01“…The water environment of Shenzhen Bay,one of the key waters in the Guangdong-Hong Kong-Macao Greater Bay Area,is mainly influenced by the urbanization of the surrounding areas.Water resource protection and water environment governance are particularly important for Shenzhen,a water-deficient city.This paper explores the specific influence relationship between each factor and the water environment in the process of urbanization.The comprehensive water pollution index and Pearson correlation analysis are utilized to analyze the relationship of the changes in population size and industrial structure with the water environment of Shenzhen Bay in urbanization.The research shows that the main pollutants in the water environment of Shenzhen Bay are chemical oxygen demand (COD) and ammonia nitrogen (NH<sub>3</sub>-N),and some pollutants come from urban non-point source pollution.The water quality in Nanshan District is good,while that in Futian District is poor,but the overall water quality shows a trend of improvement.The water environment is less affected by population change and more affected by industrial structure change.Therefore,formulating reasonable policies to guide the transformation of the industrial structure is an effective way to improve the water environment of Shenzhen Bay.…”

Analysis of Agricultural Non-point Source Pollution in A Small Watershed in Typical Mountainous Areas at Dongjiang Headwaters ——Taking the Dongjiang Watershed in Dingnan County as...
Published 2023-01-01“…The current situation of agricultural non-point source pollution in a small watershed in typical mountainous areas at Dongjiang Headwaters were investigated and analyzed,and the agricultural non-point source pollution sources,pollution load and pollution load intensity in this watershed were analyzed,so as to provide a reference for ensuring the safety of water sources in the Guangdong-Hong Kong-Macao Greater Bay Area and promoting the precise pollution control in the watershed.The pollution types such as human settlements,agricultural planting,livestock and poultry breeding and aquaculture in the Dongjiang River Basin of Dingnan County were classified and investigated at the scale of county and township.The pollution load and pollution load intensity were estimated using the output coefficient method and the equivalent pollution load method,and the spatial distribution of pollutants was analyzed by clusteranalysis and ArcGIS.It was found that the main pollutants from agricultural non-point sources in the Dongjiang River Basin of Dingnan County were TN and NH<sup>+</sup><sub>4</sub>-N,which mainly came from human settlements and agricultural planting,and the pollution sources were concentrated in Lishi Town and Egong Town.Strengthening residents' awareness of water environmental protection,speeding up the construction of supporting sewage pipe networks,strengthening the operation and management of sewage equipments,and rationally applying nitrogen and phosphate fertilizers are of great significance for promoting the continuous emission reduction of agricultural non-point source pollution in the mountainous watershed at Dongjiang Headwaters.…”
