利用阿克苏绿洲农田试验站连续测定的棉田土壤呼吸值及同步测定的土壤温度与湿度数据,构建通用的土壤呼吸温度敏感性模型.结合构建的模型,对5个常用的土壤呼吸温度模型所模拟的研究区的土壤呼吸变化的温度敏感性进行评析.结果表明:Arrhenius模型能较好的预测研究区的土壤呼吸温度敏感性的变化;研究区土壤呼吸温度敏感性随温度的升高呈下降的趋势.两类试验样地土壤呼吸温度敏感性存在明显的差异性,这可能与两类试验样地土壤呼吸组分的差异有关,这是以后需要重点关注的地方.
By using the data of soil respiration and soil temperature and humidity measured continuously in Aksu Oasis farmland test station, a general soil respiration temperature sensitivity model was constructed. Combining with the constructed models, five common soil respiration temperature models The results showed that: Arrhenius model can predict the change of soil respiration temperature in the study area better; the sensitivity of soil respiration temperature in the study area decreased with the increase of temperature There were significant differences in soil respiration temperature sensitivity between the two types of experimental plots, which may be related to the differences of soil respiration components in two types of experimental plots, which is the focus of attention in the future.
