Abstract:The Xijiang Wuzhou Section Aquatic Germplasm Reserve is a key zone for aquatic biodiversity conservation in the Pearl River Basin. Monitoring data indicate stable water quality(Class II-III ),withapH range of 7.1~8.08 and dissolved oxygen(DO) levels of 6.12~9.49mg/L . Petroleum and phenolic pollutants have shown a consistent declining trend. A total of 59 fish species (including 5 endangered species) have been documented. The primary environmental stressors include seasonal water quality fluctuations,habitat fragmentation due to hydraulic engineering,and sporadic ilegal fishing.Based on comprehensive monitoring findings,it is recommended to:Strengthen the monitoring network and zonal management;Strictlycontrol anthropogenic disturbances,and achieve a balance between conservation and sustainable development,thereby serving as a model for aquatic germplasm resource protection in the Pearl River Basin.
Key words: Xijiang; aquatic germplasm resources; fishery environment; environmental assessment
