Other AbstractAs an epitome of human activities with high intensity, man-made ditches strongly influence the hydrological process and ecological environment of the wetland,becoming one of the main driving forces of its evolution. Based on the 27 satellite images and the topographic map with the ratio of 1:100000 of the Yellow River Delta from 1976 to 2015 , the data of the man-made ditches ( agricultural and roadside ditches ) were generated by use of the method of visual interpretation and the spatial and temporal evolution process and the driving mechanism were analyzed quantitatively. The results were as follows:(1) From 1976 to 2015,there was a significant linear increase in the length and density of man-made ditches,with the average annual growth rate of 160 km and 53 m/km2 respectively. The evolution in the length and density of agricultural ditches can be di-vided into two development stages:there was sigmoidal growth before 2000,linear growth after 2000. There was a significant linear increase in the length and density of roadside ditches,with the average annual growth rate of 141 km and 47m/km2 respectively. The length of man-made ditches had a significant linear correlation with the area of farmland (P<0. 05),a good logarithmic correlation with the area of culture ponds (P<0. 0001) and a very significant linear correlation with the road length (P<0. 0001). (3)The result of multiple regression anal-ysis showed that the synergistic effect of farmland area and road length on the length of man-made ditches was 99. 9% ( P<0. 0001 ) .
