[植][林][土壤] 枯枝落葉層
The mixed forest transformed net increase in forest litter layer of the soil surface allowed the small soil bulk density and larger soil porosity.
改造後的純林内增加了土壤表面的枯枝落葉層,從而使得其内的土壤容重小,土壤孔隙度變大;
The litter water-holding capability of the litter layer about Seabuckthorn of the arsenic sandstone areas in Dongsheng district, Erdos City was stu***d.
本文對内蒙古鄂爾多斯市砒砂岩區人工沙棘林地枯落物持水性能進行了研究。
The degradations of litter layer and nutrient pool under EF were abrupt as the traditional reforestation like cutting, firing and machinery management was implemented.
傳統的砍、燒、機耕整地使桉樹林地的枯枝落葉和養分庫呈突變形式退化。
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;
林隙土壤的枯枝落葉層比林下薄,其組分主要是草本和根系盤結物且呈半分解狀态;
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.
森林植被通過林冠層、枯落物層和根系土壤層的分層攔截吸收,起到突出的減洪減沙作用。
在生态學和環境科學領域,“litter+layer”(枯枝落葉層)指覆蓋于土壤表面的有機物質層,主要由植物殘體(如落葉、枯枝、果實等)組成。該層是陸地生态系統的重要組成部分,具有以下特征與功能:
定義與組成
“litter”指自然環境中未分解的有機殘體,“layer”表示分層結構。兩者結合後,特指森林、草原等地表由植物凋落物堆積形成的有機層。其成分包括纖維素、木質素等難分解物質,以及微生物和真菌群落。
生态功能
該層通過物理覆蓋減少土壤水分蒸發,調節地表溫度,并為土壤動物提供栖息地。微生物分解過程中釋放的養分(如氮、磷)可促進土壤肥力提升。例如,溫帶森林的枯枝落葉層年均分解率約為30%-50%,直接影響碳循環效率。
人類應用
農業上利用稭稈等植物殘體覆蓋農田,模拟自然枯枝落葉層功能,可抑制雜草生長并改善土壤結構。園藝領域也通過鋪設木屑層實現保水與病蟲害防控。
“Litter layer”是一個生态學或環境科學中的術語,通常指覆蓋在土壤表面的枯枝落葉層,由植物殘體(如落葉、枯枝、果實等)堆積形成。以下是詳細解釋:
