摘要
Abstract
[ Objective] The soil respiration was an important link of the carbon cycle in ecosystem,which was the important index or community carbon expenditure status. [Method] Soil respiration rate was measured,which changed during a day in non-growing season and growing season between three different communities in Xilin River Wetland. Atmospheric and soil temperature were measure at the same time. [Result] There was a index variation between community soil respiration intensity and temperature in Xilin River Wetland. There was a very high correlation between soil respiration intensity and temperature (R2 =0.92) ,but in different temperature range this correlation had difference. The soil respiration showed a single peak diurnal variation in Xilin River Wetland. There were significant differences in respiration intensity between non-growing and growing season. Respiration intensity in growing season was about 5 - 10 times in non-growing season. [ Conclusion ] Different communities had significant different soil respiration. Soil respiration was existed in non-growing season,and had similar character with growing season.关键词
