Abstract：From 2O21 to 2O23，the water ecological environment of the Chaobai New River was monitored，the monitoring indexes include pH value，copper， zinc，arsenic，petroleum，permanganate index，total nitrogen，total phosphorus and dissolved oxygen. The monitoring results show that the annual average values of pH value， total nitrogen， copper and zinc show a decreasing trend year by year; the annual average values of permanganate index，total phosphorus，arsenic and petroleum showed a decreasing trend from 2021 to 2022，and the values increased in July and September 2O23;the annual average value of dissolved oxygen from 2O21 to 2022 was basically stable，and overallaverage value in 2023 decreased. Analyzing the overall monitoring data reveals that the main polltion indexes of Chaobai New River are permanganate index， petroleum and total nitrogen，the relevant departments should pay attention to and strengthen the management to ensure the sustainable development of water environment in Chaobai New River area.
