forest litter-soil的意思|示意

Carbon stored in forest biomass, deadwood, litter and soil together is roughly 50 percent more than the amount of carbon in the atmosphere.

储存在森林生物量、枯木、垃圾和土壤中的碳量共大约相当大气中碳量的50%。

Forest litter has considerable eco-hydrological effects in retarding surface runoff, trapping sediment, and equilibrating soil water and heat status.

森林凋落物具有阻滞径流、拦截泥沙和均衡土壤水热状况等功效。

The mixed forest transformed net increase in forest litter layer of the soil surface allowed the small soil bulk density and larger soil porosity.

改造后的纯林内增加了土壤表面的枯枝落叶层，从而使得其内的土壤容重小，土壤孔隙度变大；

The results above provide a scientific reference for impact of logging on function of soil and litter and low-quality forest management.

以上研究结果可为采伐对土壤和枯落物功能影响的研究和低质林经营提供科学参考。

Because of the shading of wood leaf layers and litter fall, soil evaporation and the range of soil moisture contents changing were small under forest canopy.

受冠层覆盖及植被根系影响，随着树干距离的增加，土壤含水率呈减少趋势。

Through the roles of interception and absorption of the canopy layer, litter layer, and root and soil layer, the benefits of flood and sediment reduction of forest vegetation are prominent.

森林植被通过林冠层、枯落物层和根系土壤层的分层拦截吸收，起到突出的减洪减沙作用。
