Abstract: Using meteorology,hydrology and satellite remote sensing data from the Shiyang River Basin during 1959-2018,by means of linear trend rate,moving t test and Pearson correlation coefficient methods,the changing facts and correlations of ecological environment factors were analyzed.The results showed that the temperature had a significant upward trend,with a warming rate of 0.42℃·（10 a）^-1 in downstream,0.36℃·（10 a）^-1 in midstream,and 0.35℃·（10 a）^-1 in upstream,respectively.The most significant warming occurred in the last 10 years,in which it was 1.67℃higher than the 1960s.The seasonal temperature showed a significant upward trend,and the warming rate was the fastest in winter,followed by autumn,spring and summer.The precipitation increased slowly,which was 8.3 mm·（10 a）^-1 in upstream,7.0 mm·（10 a）^-1 in midstream and 4.1 mm·（10 a）^-1 in downstream,respectively.Precipitation in the last 10 years was 17%more than that in the 1960s.The increasing rate of seasonal precipitation was the fastest in summer,followed by spring,autumn and winter.The river flow was basically stable and the vegetation coverage and the normalized difference vegetation index （NDVI） increased significantly.The significant warming and humidification in the basin in the past 20 years was conducive to enhancing the total amount of local water resources,increasing the coverage of surface vegetation,and improving the ecological environment.
