佳芦河流域地处黄土丘陵沟壑区,系黄河的一级支流。该流域50年代初即开展了水土保持工作,大规模的流域综合治理始于1970年北方农业会议之后。截至1989年底止,流域内实有各项治理措施保存面积32023hm2,治理程度达28.24%。采用水文法与水保法计算流域1970~1989年水土保持措施减水32800万m2,效益20.9%;减沙6940万t,效益23.7%。
Jialuhe River Basin is located in loess hilly and gully area, the Yellow River tributary. The basin started soil and water conservation work in the early 1950s, and large-scale integrated watershed management started after the North Agricultural Conference in 1970. As of the end of 1989, there were 32023 hm2 of various governance measures in the basin and the degree of governance reached 28.24%. Using hydrology and water and soil conservation laws to calculate the water and soil conservation measures in the watershed from 1970 to 1989, the water-saving measures are 328 million m2 and the benefits are 20.9%. The sediment reduction is 69.4 million tons and the benefits are 23.7%.
