Component Analysis of Soil Respiration of Robinia Pseudoacacia Plantation in Opencast Coal Mine Reclaimation
摘要
Abstract
Quantifying soil respiration components and their relations to environmental controls are essential to estimates carbon bugets of plantation ecosystems. Trenching-plot and infrared gas exchange analyzer approaches were used to determine heterotrophic respiration (RH) and autotrophic respiration (RA) in soil surface CO2 flux for Robinia pseudoacacia plantation in the reclaimation of Antaibao Opencast Coal Mine, Shanxi. The results showed that there was a significant seasonal variation in R<RA (P<0. 01) and root respiration proportion (RC) ,but not in RA(P>0. 05) and the variant law of Rc just was converse to the law of R and RA. Both R and RH in relationship with single of soil temperature and moisture all can be described as a power function(R2 =0. 115,0. 174; P<0. 05) and liner function (r =0. 314,0. 430 ; P <0. 01) and with both of them can be described as a power function (R2 = 0. 296,0. 404;P <0. 05). Furthermore, the relationship of RH higher than R. The Q10 value, representing the sensitivity of RH to soil temperature was higher than those of R. In order to quantifying soil respiration components of Robinia pseudoacacia plantation, we should make long-term dynamic research.关键词
