Abstract:

自黄土高原退耕还林还草政策实施以来,在水源涵养功能明显提升的同时径流显著减少,导致该区域出现了水源涵养服务与水供给服务间的权衡问题。为探究径流减少的原因,进而为不同空间尺度的生态系统服务权衡提供支撑,本文分析了陕北黄土丘陵沟壑区2006-2011年降水和植被变化对径流影响的尺度效应。结果表明研究区域内汛期降水量呈现出由东南向西北逐渐减少的空间分异特征;在研究时段内,植被恢复效果明显,近8成地区植被覆盖状况得到了改善,尤其是植被覆盖较差的地区恢复效果更为显著;在各子流域中,降水与径流间呈现出显著的正相关性,二者的相关系数随着子流域面积的增加而增大,表现出明显的尺度效应。随着子流域面积增大,15°以上土地比例增加,陡坡植被覆盖类型趋于均一化,具有显著截流功能的林地呈现减少趋势是尺度效应形成的主要原因。NDVI与径流的相关性不显著,二者的相关系数随着子流域面积变化的规律性不强,植被对径流影响没有明显的尺度效应。
