    摘要:

    在分析陕南嘉陵江流域重点防治区水土保持治理前后土地利用结构变化及其成效的基础上,探讨了该区土地利用的方向和具体措施。认为,欲兼顾提高土地生产力、发展经济和保护环境,土地利用调整的方向应为:狠抓坡改梯,兴修基本农田;退耕还林,发展经果林;综合利用资源,多种经营综合开发。在具体操作时,坚持开展以小流域为单元的综合治理和综合开发,并合理利用荒山荒坡,提高土地利用率。

    Abstract:

    Landuse structure and benefits before and after comprehensive control at soil-rock mountaino us region were analyzed,the orientation and practices were probed.The result shows that the main ways to readjust landuse structure are undertaking basic farmland through building terraced fields in the slope land,stopping the cultivation,planting fruit trees,and making full use of the resources in order to develop a diversified economy,to develop economy and to protect the environment.Meanwhile,in the process of practice,by taking a small watershed as a unit,a comprehensive system for prevention and control and development would be set up,and the utilization ratio could be improved by reasonably cultivating barren hills and slopes.
