利用NCAR公用陆面模式CLM3(Community Land Model 3)模拟的土壤和植被蒸发量,分析中国区域水资源的气候特征及变化特点.总蒸发量的空间分布以35.N为界,分界线以南为高蒸发区.以北为低蒸发区,蒸发量最小的区域主要在西北地区,多年平均年蒸发量在50mm以下.四季蒸发量占年总蒸发量的百分比与水资源的情形基本一致,夏季蒸发量占年总蒸发量的40%以上.35.N以北地区可达50%以上,有些地区甚至达到70%;春季和秋季情况类似,占年总量的20%左右;冬季最少,占年总量的10%,北方地区更少.水资源线性变化趋势,35.N以北大部地区水资源呈减少趋势;其它地区,如长江以南地区、青藏高原的水资源都在增加.
