| 摘要 | As an important river in the western part of Jilin Province, the lower reach of the Nenjiang River is an important wetland water source conservation area in Jilin Province. Within the watershed, it governs the Momoge Wetland, the Xianghai Wetland, and the Danjiang Wetland in Jilin Province. The main problem in the lower reaches of the Nenjiang River is the uneven distribution of water resources in time and space, and the intensification of land salinization. Zhenlai County and Da'an City in the Nenjiang River Basin have sufficient surface water resources, with surface water as the drinking water source. Baicheng City and Tongyu County have scarce surface water resources, and both use groundwater as their domestic water source. The main polluted section in the basin is the Xianghai Reservoir, and the annual water quality evaluation is Class V. However, the water quality of the Tao'er River, the main stream of the Nenjiang River, is significantly better than that of the Xianghai Reservoir. In order to better study the water environmental pollution situation in the Nenjiang River basin, monitoring data from five sections of non seasonal rivers in the basin from 2012 to 2021 were selected for studying water quality. This in-depth exploration of the water pollution status and river water quality change trends in the Nenjiang River basin is of great significance for future rural development, agricultural pattern transformation, and the promotion of water ecological civilization construction. |
