Water loss and soil erosion is one of the most serious environment problems in china, which has slowed down the social and economic development in some rural areas. in some places of china, it has resulted in the arable degradation, soil desertification, filling up of irrigation works, and the increase of droughts and floods, etc. in consequence, the agricultural condition and ecological environment there become worse and worse. the causes of water loss and soil erosion include both unfavorable natural conditions and irrational land use, such as deforestation for cultivated land use. after analyzing the causes of soil erosion and its harms to the natural environment and human living, the author suggested some strategies for water and soil conservation, such as ecological engineering, reforestation and the application of biological technology

人工降雨實驗結果表明，在降雨強度和侵蝕強度不大時，侵蝕泥沙是全量養分流失的主體，地表徑流則是速效養分流失的主體；而當在降雨強度和侵蝕強度極為劇烈時，侵蝕泥沙成為全量養分和速效養分二者流失的主要載體；地表徑流中的養分含量很大程度上受土壤中養分含量的影響，土壤中養分含量越高，養分徑流流失的可能性越大。
