黄土高原水土流失治理进展及其对策

Research on Eco-construction and Control Measures of Soil and Water Loss in the Loess Plateau

黄土高原地区水土流失类型复杂,既有自然因素和人为因素,也有水力、风力、重力产生的变化。同时气候干旱、水资源缺乏成为植物生长和生态环境改善的最大障碍。在国家实施西部大开发的进程中,良好的生态环境成为生存与发展和建设小康社会的标志。无论从西部大开发的战略角度考虑,还是从退耕还林(草)政策实施8年以后,如何解决黄土高原地区人民群众衣食住行、经济发展问题及黄河减沙的角度来看,采取有效措施,加快该区的生态建设已势在必行。根据第十一个五年规划的建议,以生态恢复学和土壤侵蚀学的基本原理为指导,分析了黄土高原地区的重要性,探讨了黄土高原生态建设与经济发展的基本现状,因地制宜地提出了发展对策。

There are complicated categories of soil and water loss in the loess plateau region, such as natural factors and artificial factors, and annual variation of hydraulic, wind power and gravity. At the same time, arid climate and water scarcity have became the greatest obstacle to plant growth and eco-environment improvement. In the process of west development, a good eco-environment is a sign of subsistence and development and a well-off society. Based on suggestions of the eleventh five-year-plan, in accordance with the principles of ecological rehabilitation, analysis the importance of the loess plateau, the status of ecology construction and economic development are discussed, puts forward some proposals ac cording to conditions.
