Soil nutrient loss的意思|示意

Man made accelerated erosion is a key reason for soil nutrient loss after forestlands were disturbed by human being.

林地被人为开垦破坏后，加速侵蚀是导致坡面土壤养分流失的根本原因。

Soil nutrients abruptly loss in the beginning stage of forest removal. After five years of forest removal, soil nutrient content reduces by 50%.

土壤养分流失在开垦初期非常迅速，开垦耕种5 a后，土壤养分含量可减少5 0 %。

Due to the increase in nutrient input of the ecosystem and the decrease in the nutrient output from soil and water loss, the nutrients in the system are surplus.

由于间种山毛豆增加了生态系统的养分收入，减少了水土流失的养分支出，系统的各种养分出现了盈余的状况。

Sloping spatial distribution of soil nutrient loss responds to spatial distribution of soil erosion patterns erosion intensity. Shallow gully ditch is the severest position of soil nutrient loss.

坡面土壤养分流失的空间分布与坡面侵蚀方式和侵蚀强度的空间分布相一致，浅沟沟槽是坡面土壤养分流失最严重的部位。

The process of soil nitrogen loss in runoff and sediment is restricted by interaction of soil nutrient with rainfall and runoff.

坡地土壤养分流失过程实际上是表层土壤养分与降雨、径流相互作用的过程，土壤养分流失的多少主要受相互作用的限制。

The results showed that compared with the bare land, all restoration patterns played positive effect in the control of soil erosion and nutrient loss in the gangue pile land.

结果表明：与裸地相比，不同椬被恢复模式均对矸石山坡面土壤侵蚀和养分流失具有明显控制效果；
