Soil Respiration under Three Landuse Categories of Mountainous Region in Xishuangbanna, Yunnan

doi:10.3724/SP.J.1143.2012.11177

Abstract

Abstract:

In order to study the difference of the soil respiration under different landuses in Xishuangbanna, field observations were conducted on the soil respiration rate from November 2010 to May 2011 under forest tea plantations, terrace tea plantations and secondary forests. Daily variations of soil respiration and its influence factors were analyzed. The results showed that there are different dailychange patterns of soil respiration rate and soil moisture under different landuses, with statistically insignificance of soil respiration rate (P<0.05). The daily maximum soil respiration rate is almost at 14∶00-16∶00. The soil respiration rate and soil moisture vary most during the dry rainy transition season. The average soil respiration rate: forest tea plantations (2.62μmol·m-2s-1)

Key words: Xishuangbanna, Soil respiration, Dry season, Forest tea plantation, Terrace tea plantation, Secondary forest
