Abstract:

利用净初级生产力模型C-FIX,陆面过程模型CoLM以及高时空分辨率的遥感数据集,定量估算了2002年西部地区1km分辨率的水分利用效率(WUE)时空格局分布.模型估算2002年西部地区净初级生产力总量约为0.96PgC,蒸散发总量约为2098km3,整个西部地区平均单位面积上年均WUE约为0.32gC·mm-1.西部地区WUE时空分布格局具有显著的异质性WUE最高值区主要分布在新疆西北部的天山和阿尔泰山区域,年均WUE最高可达4gC·mm-1·m-2;其次为西藏东南隅以及陕西和甘肃南部山区,年均WUE约在1~2gC·mm-1·m-2之间.WUE最低值广泛分布在青藏高原地区和西北沙漠地区,年均WUE基本在0.4gC·mm-1·m-2以下.研究发现,西北干旱区内陆河流域荒漠植被呈现出相对高的WUE水平,反映出适度水分亏缺地区的天然植被生态系统可能具有较水分充足地区植被生态系统更高的水分利用效率功能.通过定量分析比较不同植被生态系统WUE特征及其季节变化廓线,得到西部地区主要植被生态系统的年均WUE大小为山区森林>荒漠乔灌丛>灌溉农田>高寒草地>寒漠和戈壁.
