| 摘 要： | 冻融交替是作用于土壤的非生物应力,对土壤的理化和生物学性质均产生直接或间接影响.在气候变暖条件下,冻融作用对冻土区土壤碳库关键生物地球化学循环过程的影响已成为当前研究的热点.经过室内冻融模拟结合野外观测,大量研究结果表明不同冻融温度、速率、次数对土壤有机碳和微生物的影响不同.冻融作用能改变土壤理化性质,降低土壤团聚体稳...

| Abstract: | As an abiological effect on soil environments,the freeze-thaw process directly or indirectly influences the physical,chemical and biological properties of soils.Under warming climate,increasingly attention has been paid to the effect of soil freezing-thawing alternation on carbon and nitrogen biogeochemical cycles.Through controlled laboratory experiments and in-situ observations of the freeze-thaw process,many studies have demonstrated that different temperature changing rates and frequencies of the freeze... |
