中国水土保持成就与展望

水土流失对人类生存环境极为不利，它是人类诸多灾害的根源。全世界约有２５００万ｋｍ２土地遭受水土流失。中国的水土流失面积达３６７万ｋｍ２。１９４９年以来，中国已累计综合治理水土流失面积７０万ｋｍ２，建设基本农田１１３万ｋｍ２。当前水土保持工作中存在诸如重视不够、法制观念淡薄、投入不足、科研和技术推广落后等问题。要防止人为造成新的水土流失，抢救一切可抢救的土地，建设一支高素质的水土保持队伍，建立水土流失动态监控预报系统

Success and Prospect of Soil and Water Conservation in China

Soil and water loss does enormous harm to human ecologic environment.It causes various disasters.In the world,the total soil and water loss stricken area is 25000000km 2.In China,since 1949 the soil and water loss area has reached 3670000km 2,of which 670000km 2 has been brought under control in a comprehensive way, and 107000km 2 cultivable farm land has been built.The major problems in the present soil and water conservation are insufficient attention,lach of conciousness in preservation,shortage of funds,and insufficient approaches to spreading advanced sci technical methods or experience.Work must be done to prevent further human activity induced soil and water losses ,to preserve all lands,to train qualified special staff and to set up dynamic observation systems for soil and water conservation.
