摘　　要：贵州旱坡耕地水土流失面广、程度较重、危害大 ,为此 ,全省开展了旱坡耕地坡改梯工程、生物护埂梯化和农艺技术试验研究 ,并示范推广。通过实施土面平整、拦截水土等措施 ,控制水土流失 ,加速坡土梯化和培肥土壤的进程 ,实践证明在贵州省山区耕地 ,特别是旱坡地采用是可行的。这项技术的科学性和实用性 ,在全省推广应用带来了良好的生态效益、经济效益和社会效益。The comprehensive measures of terrace engineering, terraced by hedgerow and agronomic technique were (studied) and demonstrated for controlling the serious soil loss of uplands in Guizhou. A set of measures including land terracing, soil and water protection, soil erosion control, speeding up engineering of terraced fields and improving soil fertility is suited and practicable in mountainous area especially in uplands. The demonstration and application of these measures have brought obvious ecological, economic and social benefits.
