soil and nutrient loss

基本解释

Influence of different drainage conditions on soil erosion and nutrient loss of slope land;
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 erosion and nutrient loss directly result in soil fertility degeneration, and also seriously threaten the natural environment.
土壤氮素随径流流失不仅造成土壤肥力退化，而且对人类生存的自然环境造成危害。
Prediction of soil erosion and nutrient loss quantity was conducted in Guishan Mountain, Caohu using the SCS model, the USLE model, the iron nails method and a nutrient loss formula.
本文通过大量的调查和实验，对土壤养分流失的机理和时空变化规律进行了分析，结果表明：泥沙流失是土壤养分流失的主要因素，随坡度增大土壤养分逐渐降低。
