Diurnal Variation of Soil Respiration and Its Temperature Sensitivity in Kandelia candel Mangrove Wetland
摘要
Abstract
The diurnal variation oi soil respiration was studied by Li-8100 at Kandelia candei mangrove wetland in Jiulongjiang Estuary on 8 July,2 October in 2010 and 15 January,11 April in 2011 respectively. Similar pattern was found in the diurnal variation of soil respiration on 2 October and 11 April with the maximum values at 14:00 and the minimum at 00:00. The diurnal pattern on 8 July and 15 January was completely different,the maximum values appeared at 10;00 and 08:00 and minimum at 22:00 and 04:00,respectively. The daily mean values of soil respiration appeared between 06;00 to 10:00. There was a significantly positive correlation between soil respiration and soil temperature at 5 cm depth (p＜0. 01 ). The exponential model indicated that soil temperature at 5 cm depth could explain 74. 4% of soil respiration in K. Candel mangrove wetland.关键词
