土壤有机质分解的温度敏感性:培养与测定模式
Temperature sensitivity of soil organic matter decomposition: New insights into models of incubation and measurement
摘要
Abstract
The temperature sensitivity (Q10) of soil organic matter decomposition is not only one of the core issues in ecology and soil science but also one of the key topics in global change ecology.Some scientists have studied the underlying mechanisms and factors that influence Q10 using empirical methods.However,few previous studies considered the methods used for soil incubation and soil respiration measurement.In this study,we briefly introduce the theory and methods by which Q10 is calculated.We examine advantages and disadvantages of two approaches commonly used in soil incubation and soil respiration measurement.Furthermore,we describe a newly developed method that includes continuous incubation with variable temperature and rapid automatic measurement.Finally,we discuss the potential applications of this novel approach,which can result in a more accurate determination of Q10.More importantly,we emphasize the need for young scientists in China to critically examine their methodology,as well as to develop new instrumentation and integrate new technology into their research.关键词
