摘　　要： 为了弄清贵州省坡耕地的利用情况，对贵州省坡耕地的整理潜力进行了研究。采用文献资料、实地调研和资料对比分析法，对贵州省6°～25°坡耕地的整理潜力进行了分析。结果表明：贵州省坡耕地主要集中在6°～25°，占全省耕地总面积的63．44％。其中，梯田总面积80．39万hm^2，旱坡地总面积205．42万hm^2。通过工程整理措施，梯田整理新增耕地率6°～15°为3％，15°～25°为4．5％；旱坡地整理的新增耕地率为6％，15°～25°为5％。经整理后的耕地生产能力明显提高，确定了6°～25°耕地整理折抵新增耕地的折算系数：梯田为0．6，旱坡地为0．42。 The arrangement potentiality of the slope farming land with 6°-25° was analyzed by using documents, on-the spot investigation and the contrast analysis method to know its utilization situation in Guizhou. The results show that the slope farm land with 6°-25° accounts for 63.44% of the total farming land, of which, the total terrace field area is 0. 8039 million hm^2 and total dry slope land is 2. 0542 million hm^2. The farming rate of the terrace fields with 6°-15° and with 6°-15° increases by 3% and 4.5%, and the farming rate of the dry slope land with 6°-15° and with 6°-15° increases by 6% and 5% respectively by using arrangement measures. The productive ability of the arranged farming land is raised significantly and its conversion coefficient of the terrace field and dry slope land with 6°-25° by raising the land productivity is 0. 6 and 0. 42 separately.
