Water pollution in the Xiang River Basin of China is exacerbated by continuous population growth, rapid economic development, and accelerating urbanization. Abundant pollutants from various sources significantly degrade the basin's water quality. The degradation of water quality influences the economic and social development in urban agglomeration along the basin. To analyse the current status and explore appropriate regulatory measures of water pollution in the Xiang River Basin of China, this paper discusses causes, current status and variations of water pollution in the Xiang River Basin based on the 2002-2015 statistical data of urban agglomeration and environmental pollution in the basin. Results demonstrated that the Xiang River basin is moderately polluted. The majority of the basin's water bodies are polluted at the III-level. Approximately 70% of total pollution in the basin is contributed by III-level, IV-level, V-level, and inferior V-level pollution. Large-scale industrial wastewater drainage, extensive pesticide use, urban sewage pollution, and ineffective government control measures are the main causes of water pollution in the Xiang River basin. Water pollution in the basin has the following characteristics: 1) water pollution is becoming increasingly complicated; 2) industrial waste gas and atmospheric pollution intensify water pollution; 3) degradation of ecological and environmental functions causes abnormal self-recovery of the water body; 4) large-scale exploitation of mineral resources intensifies water pollution. Water pollution in the Xiang River basin can be effectively improved by perfecting the legal constructions of scientific decision, administrative organization, and public participation. Results in this paper can provide scientific and accurate references to understand causes and current status of water pollution in the Xiang River basin, to continuously increase the regulation level of water resource management, and to help related departments in the continuous utilization and optimal configuration of water resources in Xiang River.

Abstract


Water pollution in the Xiang River Basin of China is exacerbated by continuous population growth, rapid economic development, and accelerating urbanization. Abundant pollutants from various sources significantly degrade the basin's water quality. The degradation of water quality influences the economic and social development in urban agglomeration along the basin. To analyse the current status and explore appropriate regulatory measures of water pollution in the Xiang River Basin of China, this paper discusses causes, current status and variations of water pollution in the Xiang River Basin based on the 2002-2015 statistical data of urban agglomeration and environmental pollution in the basin. Results demonstrated that the Xiang River basin is moderately polluted. The majority of the basin's water bodies are polluted at the III-level. Approximately 70% of total pollution in the basin is contributed by III-level, IV-level, V-level, and inferior V-level pollution. Large-scale industrial wastewater drainage, extensive pesticide use, urban sewage pollution, and ineffective government control measures are the main causes of water pollution in the Xiang River basin. Water pollution in the basin has the following characteristics: 1) water pollution is becoming increasingly complicated; 2) industrial waste gas and atmospheric pollution intensify water pollution; 3) degradation of ecological and environmental functions causes abnormal self-recovery of the water body; 4) large-scale exploitation of mineral resources intensifies water pollution. Water pollution in the Xiang River basin can be effectively improved by perfecting the legal constructions of scientific decision, administrative organization, and public participation. Results in this paper can provide scientific and accurate references to understand causes and current status of water pollution in the Xiang River basin, to continuously increase the regulation level of water resource management, and to help related departments in the continuous utilization and optimal configuration of water resources in Xiang River.
