Abstract:: This paper mainly used field survey and lab test, ‘space replacing time’ method to study the water accumulation and retention efficiency of litter under various measures of ecological restoration in water source conservation areas of Taolinkou reservoir, including the storage capacity, water absorption rate, water holding capacity, effective retaining amount, etc. The results indicated that: (1) the storage capacity of litter under different measures of ecological restoration increased obviously, which of natural secondary forest regeneration type was maximum, reaching 26.88 t/hm², while that of barren slope regeneration type was least, reaching 9.57 t/hm²; (2) according to the regression analysis, there was a logarithmic function relationship between water holding capacity and water immersion time, and there was a power function relationship between water absorption rate and water immersion time; (3) the effective retaining amount of litter under different measures of ecological restoration increased obviously, which of natural secondary forest regeneration type was maximum (8.51 mm), while that of barren slope regeneration type was the least (2.85 mm). And the effective retaining amount of litter after ecological restoration increased obviously, whose increases range from 20.41% to 98.63%.These results provided a scientific basis for evaluating water accumulation and containing efficiency of litter in water source conservation areas of reservoir under different measures of ecological restoration.
