碱测定法

Soil respiration response to different stages of vegetation restoration was determined via closed system measurements of carbon dioxide and selected factors affecting the correctitude and sensitivity of soil respiration. Eight different soil samples under different vegetation restoration stages were separately collected at 0~20 cm and 20~40 cm soil depth in spring and summer and both fresh and air-dried samples analyzed.
