Abstract:

基于MOD16数据产品结合气象数据,统计分析了陕西省2000-2013年地表蒸散的时空分布特征,研究表明MOD16蒸散产品能够满足陕西省地表蒸散时空分布研究的要求,结果对陕西省水资源的有效利用具有重要的理论和实践意义。主要结论:(1)2000-2013年蒸散(ET)、潜在蒸散(PET)年际波动不大,全省ET平均值在490mm左右,PET平均值在1550mm左右,年平均ET与PET的差距说明陕西省较为干旱缺水。全省ET、PET的年内变化都呈单峰分布趋势,两者变化存在差异,6月两者差距最大,此时最为缺水。(2)陕西省不同区域蒸散有明显的空间分布差异,陕西南部水分较为充足,而在陕西北部较为缺水。陕西中西部区域干旱有所缓解,中东部区域干旱加重。(3)各功能区年平均ET与PET大小顺序正好相反,干旱程度顺序为防风治沙工程区>陕北退耕还林区>渭北退耕还林区>关中农业生产区>陕北天然林保护区>陕南退耕还林区>陕南天然林保护区。各功能区年内ET月平均变化差异明显,可分为三类,单峰型、波动型、双峰型。(4)蒸散的时空变化与气候特点,特别是水热条件的时空变化有很高的相关关系,而与植被的分布和生长状况也紧密相关。
