重庆市黔江区地处武陵山区腹部,属于典型的山区地貌,15°以上的坡耕地面积占耕地总面积的84.52%,面积大,范围广,集中分布在全区三大流域。在分析区域坡耕地利用状况的基础上,针对坡耕地利用中存在的水土流失严重、生态环境日益恶化的问题,提出了以小流域为治理单元对坡耕地进行综合治理。
Qianjiang District of Chongqing City is located in the belly of Wuling Mountain Area. It is a typical mountainous landform. The sloping arable land above 15 ° occupies 84.52% of the total arable land. It has a large area and a wide range and is mainly distributed in the three major drainage areas of the region. Based on the analysis of the utilization status of sloping arable land in the region, aiming at the serious problems of soil and water loss and the deterioration of ecological environment in the utilization of sloping land, we put forward to take the small watershed as the governing unit to comprehensively control the sloping land.
