| 摘 要： | 利用静态箱法对泥河水库秋季水-气界面二氧化碳通量值进行连续24h观测,对其变化趋势及影响因素加以分析。结果表明：泥河水库24h均为大气的源,其碳通量均值为24.53mg·m-2.h-1,呈现出双峰值特点。全天源的极大值出现在22∶00为35.57mg·m-2.h-1,源的极小值出现在10∶00为12.57mg·m-2.h-1。在秋季影响水库水-气界面碳通量变化的主要因素是温度、风速、溶解有机碳（DOC）和碱度。秋季泥河水库CO2排放量不是很大,但仍是大气二氧化碳的碳源之一。 |

| Abstract: | Static chamber method was used to observe diurnal variation of CO2 fluxes at the water-air interface of Nihe reservoir 24 hours continuously in autumn.And the changing together with the influencing factors was analyzed.Results show that Nihe reservoir is a total carbon source in twenty-four hours with mean flux value of 24.53(mg m-2 h-1),presenting a feature of double-peak.The maximum and minimum flux values are 35.57(mg m-2 h-1) at 22:00 and 12.57(mg m-2 h-1) at 10:00 respectively.The air temperature,veget... |
