森林枯落物(枯枝落叶)是指覆盖在林地矿质土壤表面上的新鲜、半分解的植物凋落物,它是森林植物地上部各器官的枯死、脱落物的总称。从整个林相的剖面上看,枯落物是除林冠层、下木和层外植物之外,大气与矿质土壤、植物根系间进行物质与能量交换的另一个介质。它的存在,是森林土壤与其它各类土壤在剖面形态上相区别的标志之一。在影响林地土壤的水热状况、通气状况、营养元素的循环、林地生物种群的类型及数量、林地水文生态特性等方面,以及在整个土壤——植物——大气连续系统中,森林枯落物层均起着重要的作用。正因为如此,它引起了生态、水文、土壤及土壤保持等学科研究工作者的强烈兴趣。他们从各种不同角度,运用不同方法和手段,对枯落物的作用进行了广泛而深入的研究。随着
Forest litter (litter) refers to the fresh, semi-decomposed plant litter that covers the surface of forest mineral soils and is the collective name for the dead, shedding of various organs above the ground of forest plants. From the section of the entire forest facies, litter is another medium for the exchange of matter and energy between the atmosphere, mineral soils, and plant roots in addition to the canopy, understory and extra-terrestrial plants. Its existence is one of the signs that the forest soil and other types of soils are different in profile. In the field of soil-plant-atmosphere continuum, the effects of forest soil water and heat, aeration, nutrient cycling, the types and quantity of woodland biological species, the hydrological and ecological characteristics of forest land, Layers play an important role. Because of this, it has drawn strong interest from academic researchers in ecology, hydrology, soil and soil conservation. From a variety of perspectives, they used different methods and means to conduct a comprehensive and in-depth study on the role of litter. along with
