Time effect of photosynthetic carbon fixation of cyanobacterial crusts in arid artificially revegetated areas .

干旱人工植被区藻结皮光合固碳的时间效应研究。

To investigate the effects of soil temperature and soil moisture on soil respiration , we measured soil respiration rates of a revegetated area and a shifting sand area in the tengger desert using the li-6400-09 soil respiration chamber technique .

利用li-6400-09土壤呼吸室和li-6400便携式光合测定仪，在植物生长季对腾格里沙漠东南缘植被区和流沙区的土壤呼吸进行了连续测定，并分析了温度和水分对土壤呼吸的影响。
