摘要
植物凋落物是土壤动物和土壤微生物的主要生命物质和能量来源,其类型、组成以及物理化学等性质直接决定了土壤有机质的品质。对植物凋落物的类型、品质、物理性质、层效应和激发效应以及根际碳淀积与土壤有机质分解的关系进行了总结,可为研究植物凋落物对土壤有机质的影响提供理论参考,指出要在全球变暖背景下进一步加强凋落物分解过程中土壤微生物和酶活性变化的研究。
Plant litter is the main organic material and energy source for soil fauna and microorganisms. Litter types,composition,and physico-chemical properties influence the quality of soil organic matter. In this review,we examined the relationship between the types,quality,physical properties,layer effects,priming effects,carbon deposition in the rhizosphere of plant litter and the decomposition of soil organic matter. This review provides a theoretical basis for the study of the effects of plant litter on soil organic matter.We suggest that the effects of plant litter decomposition on the soil micro-organisms and enzyme activities need to be further explored in the context of global warming.
