我国是一个多山的国家,山区约占国土总面积的三分之二,人均山地近8亩.山区经济的发展在社会主义建设中具有极其重要的战略地位。但是,由于复杂的自然条件和历史上长期滥用自然资源等原因,大多数山区水土流失严重,阻碍着农业生产的发展和人民生活水平的提高。防治水土流失,保护和合理利用水土资源,是改变山区面貌,减少水旱灾害,建立良好生态环境,增强农业发展后劲,加快山区群众奔小康步伐的一项根本措施。
China is a mountainous country, with mountainous areas accounting for about two thirds of the total land area and nearly 8 mu of mountainous per capita. The development of mountain economy has an extremely important strategic position in the socialist construction. However, because of the complicated natural conditions and the long history of abuse of natural resources, most of the mountainous areas suffer from soil erosion and soil erosion, hindering the development of agricultural production and the improvement of people’s living standards. Prevention and control of soil and water loss, protection and rational utilization of water and soil resources are fundamental measures for changing the face of mountainous areas, reducing floods and droughts, establishing a good ecological environment, enhancing the stamina in agricultural development and speeding up the pace of mass affluence in the mountainous areas.
