| 摘 要： | 以重庆市南川区木渡河小流域为研究对象，对岩溶槽谷区坡改梯和利用自然地块生产进行了对比分析。石漠化程度在25%以下的区域，可以实施高标准的坡改梯工程，以增加耕地面积；石漠化程度在25%以上的区域，最好利用自然地块进行生产，并逐步过渡到经济作物的开发。利用自然地块进行生产的关键在于辅以简单的工程措施，并使工程措施与生物措施有机结合，以达到最大限度减少水土流失的目的。

| Abstract: | The advantages and disadvantages of farmland terracing and natural plot were discussed taking for example of Muduhe small watershed in karst valley area.The farmland terracing can be taken into account in the area that the level of karst rocky desertification is less than 25% in order to increase the basic farmland.The land utilization patterns of natural plot should be carried in the area that the level of karst rocky desertification is greater than 25% and will be removed to the planting of cash crops.It was the crux of natural plot utilization that the simple engineering measures was carried and the bio-control method and engineering measures should be combined in order to assembly minimize soil and water loss. |
