This paper analyzed seasonal dynamics of soil respiration through alkaline absorption methods in Lymus chinensis and Puccinellia tenuiflora communities. The relationship between soil respiration and environmental factors was also discussed through Grey analysis. The results were as follows: (1) The seasonal dynamics of soil respiration showed a single peak curve with the maximum 13.27 g/(m 2·d) in the middle August in Lymus chinensis community and with the maximum 11.4 g/(m ...

This paper analyzed seasonal dynamics of soil respiration through alkaline absorption methods in Lymus chinensis and Puccinellia tenuiflora communities. The relationship between soil respiration and environmental factors was also discussed through Grey analysis. The results were as follows: (1) The seasonal dynamics of soil respiration showed a single peak curve with the maximum 13.27 g/(m 2·d) in the middle August in Lymus chinensis community and with the maximum 11.4 g/(m 2·d) in the middle July in Puccinellia tenuiflora community; (2) Among eleven environmental factors, pH, wind velocity, soil water content, porosity and organic matter content kept a bigger Grey connection degree opposite CO 2 release rate of soil respiration and were major factors. The ration between organic carbon and nitrogen, soil temperature and precipitation kept a smaller Grey connection degree and were limited factors of soil respiration; (3) The regression models were established between CO 2 release rate of soil respiration ( y ) and soil water content at 0-10cm-depth (x): y =126.51 x -6.512 1 ( R 2 =0.92, P <0.05) in Lymus chinensis community and y=60.425x-1.702 4 in Puccinellia tenuiflora community (R 2=0.98,P <0.05).

用静态气室法对羊草群落和碱茅群落的土壤呼吸量进行测定 ,分析了 2种群落土壤呼吸量的季节动态及其与环境因子的关系。结果表明 :1) 2种群落土壤呼吸量的季节动态均呈单峰曲线 ,羊草群落的土壤呼吸量在 8月中旬达最大值 13.2 7g/ (m2 · d) ,碱茅群落土壤呼吸量在 7月中旬达最大值 11.4 g/ (m2 · d)。 2 )在 11种环境因素中 ,p H、风速、土壤含水量、孔隙度和有机质含量对 2种群落土壤呼吸量均有较大的灰色关联度 ,是主要因素 ;地温和降水量对 2种群落土壤呼吸量的灰色关联度较小 ,是限制因素。 3)建立了 2种群落土壤呼吸量 (y)与土壤 0~ 10 cm含水量 (x)的回归模型。羊草群落 :y=12 6 .5 1x- 6 .5 12 1  (R2 =0 .92 ,P<0 .0 5 ) ;碱茅群落 :y=6 0 .4 2 5 x- 1.70 24 (R2 =0 .98,P<0 .0 5 )
