摘要: 采取野外观测与室内分析化验相结合的方法,对具有代表性的紫色坡薄地上实施的工程改立项目进行效益定位监测,结果表明,坡薄上水土流失受到抑制,水热矛盾日趋协调,土壤养分状况改善,"陡薄瘦蚀旱"得到缓解,收到了形质兼改的效果。

Abstract: The effect of soil engineering on the soil properties of the slope and meagre purplish soil was evaluated by field detection and labatory analysis.The results indicated that the soil and water erosion was controled; Tbe contradiction of water and heat was gradually coordinated; The nutrients content was increased. The soil with "slope, meagre, thin, erosion and drought" previously was improved in the aspects of physical and chemical properties.

Key words: SOIL ENGINEERING, SOIL PROPERTIES, SLOPE AND MEAGRE PURPLISH SOIL, SOIL FERTILITY
