典型草原区生长季能量平衡闭合分析

根据锡林浩特国家气候观象台2007～2009年生长季（5～9月份）湍流通量与辐射通量连续监测资料,结合同步气象资料，运用线性回归、能量平衡比率对该地区不同天气状况下能量平衡闭合进行了分析，结果表明：生长季晴天能量平衡比率99.0%，日均能量平衡比率66.7%；生长季阴天能量平衡比率110.3%，有效能量小于湍流能量，日均能量平衡比率64.3%，存在能量不闭合现象。

Typical steppe zone energy balance closure analysis of the growing season

According to the National Climate Observatory Xilinhot 2007-2009 growing season（from May to September） continuous turbulent flux and radiation monitoring data,combined with synchronous meteorological data,using linear regression,the ratio energy balance method in different weather conditions in the region the energy balance closure was analyzed.The results showed that：sunny growing season,the energy balance ratio of 99.0%,average daily energy balance ratio of 66.7%;growing season,the energy balance ratio of 100.8% cloudy days,effective energy is less than turbulent energy,average daily energy balance ratio of 64.3%,there is the phenomenon that energy is not closed.
