Research on the Impact of Ecological Water Replenishment in Diaokou River on Typical Physical and Chemical Indicators of Shallow Soil
From 2011 to 2023,a continuous 14-year ecological water replenishment initiative significantly improved the ecological environment of wetlands along the Diaokou River.To scientifically assess the effectiveness of ecological water replenishment on the improvement of wetlands,particularly the shallow soil,along the Diaokou River,the research team set up monitoring sections within the Shandong Yellow River Delta National Nature Reserve,specifically at the Yiqian'er Monitoring Station.Prototype monitoring of typical physical and chemical indicators of soil(total salinity,alkali-hydrolyzable nitrogen,available potassium,available phosphorus)is conducted according to frequency.Combined with meteorological data,it is determined that ecological water replenishment had a beneficial effect on the physical and chemical indicators of shallow soil within 0.8km along the Diaokou River,improving the ecological environment.The amplitude of changes in typical physical and chemical indicators generally follows the pattern that the closer the distance to the river,the greater the amplitude of change,while the farther the distance from the river,the smaller the amplitude of change.
