摘要:
以桃林口水库水源涵养区不同生态修复措施下枯落物为研究对象，通过野外调查与室内测试相结合、“空间代替时间”的方法，研究了不同措施及措施实施前后枯落物的蓄积量、吸水速率、持水量和有效拦蓄量等蓄水保水效益。结果表明：生态修复措施的实施增加了林内枯落物的蓄积量，枯落物蓄积量天然（次生）林封育型（26.88 t/hm2）>疏林补植型（25.83 t/hm2）>人工林封育型（25.11 t/hm2）>荒坡造林型（24.10 t/hm2）>陡坡梯田退耕型（12.22 t/hm2）>荒坡封育型（9.57 t/hm2），且生态措施实施前后的差异显著；枯落物持水量与浸泡时间之间存在对数关系，枯落物吸水速率与浸泡时间间存在乘幂函数关系；不同修复措施间枯落物的拦蓄量差异显著，天然（次生）林封育型枯落物有效拦蓄深最大（8.51 mm），荒坡封育型的有效拦蓄深最小（2.85 mm），其他依次为荒坡造林型（5.22 mm）、疏林补植型（5.13 mm）、人工林封育型（4.51 mm）、陡坡梯田封育型（3.92 mm），生态修复措施的实施增加了枯落物拦蓄量，增幅为20.41%～98.63%。研究结果为评价水库水源涵养区不同生态修复措施蓄水保水效益提供了基础。
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.
