Impact Analysis of Precipitation and Land Cover Change on Runoff and Sediment in Sanchuanhe River Basin
Climate change and human activities in the Yellow River basin have had a profound impact on the runoff-sediment process.Based on the measured hydrological data and remote sensing images from 1999 to 2019,the M-K method was used to reveal the change characteristics of precipitation,runoff and sediment,and the effects of precipitation and land cover change on runoff and sediment were illustrated by regression analysis method.This study helps to scientifically understand the impact of precipitation and land cover change on the sudden changes in water and sediment in the Sanchuanhe River Basin,and is of great significance for ecological protection and high-quality development in the Yellow River Basin.
