  1. 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

    中國是世界上水土流失最嚴重的國家之一，水土流失已成為我國的頭號環境問題.它不僅造成土地資源的破壞，導致農業生產環境惡化，生態平衡失調，水災旱災頻繁，而且妨礙社會經濟的發展和人民生活水平的提高.從自然條件和人為因素等方面出發，探討了我國水土流失產生的原因;分析了水土流失對耕地資源、旱澇災害、水資源利用、經濟發展等方面的影響;介紹了水土保持的一些有效途徑和措施
