1·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；
2·The litter water-holding capability of the litter layer about Seabuckthorn of the arsenic sandstone areas in Dongsheng district, Erdos City was studied.
本文对内蒙古鄂尔多斯市砒砂岩区人工沙棘林地枯落物持水性能进行了研究。
3·The degradations of litter layer and nutrient pool under EF were abrupt as the traditional reforestation like cutting, firing and machinery management was implemented.
传统的砍、烧、机耕整地使桉树林地的枯枝落叶和养分库呈突变形式退化。
4·The litter layer in forest gaps was thinner than that under the canopy, the composition of the litter layer was herb remains and root twister while that was in half decomposition;
林隙土壤的枯枝落叶层比林下薄，其组分主要是草本和根系盘结物且呈半分解状态；
5·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。
6·At last in order to analyze the improved effect on soil, the staggered research was discussed in the following aspects: infiltration capacity of soil, water holding capacity for soil and litter layer.
从土壤入渗功能、枯枝落叶层最大持水量以及土壤贮水能力等方面进行研究，探讨不同植被类型对土壤的改良效果。
7·The biomass of herb layer is reducing and the thickness of litter is increasing.
草本层生物量在减少，枯落物的覆盖厚度在增大。
