黄土高原风沙区综合治理关键措施组合模式

通过对黄土高原风沙区已治理典型小流域水土保持治理措施的总结,选择基础资料比较详实的典型区,从土壤侵蚀、治理目标、关键措施及其相互之间关系等方面进行典型调查分析比较和效益评估,探讨了水土保持综合治理关键措施与组合方案。目前,在西部大开发中,风沙区的生态环境势必要优先考虑,统筹安排。否则不仅西部大开发难以顺利进行,也将会直接影响到东部地区经济的持续、稳定发展和人民生活质量的进一步提高。研究风沙区综合治理对实施以减沙治沙、恢复重建生态环境为目的的水土保持生态环境建设具有十分重要的意义。

Combination Pattern of Key Countermeasures of Comprehensive Control in Wind-sandy Area of Loess Plateau

Based on summaries of soil and water loss control measures in some typical controlled watershed in wind-sandy area of loess plateau, several typical watersheds with abounded basic information in control methods, geography, social system, etc. are selected. Through examples analysis on the relationship and interaction of factors such as soil erosion intensity, designed management goal and key control methods, and those factors' combination, and also analysis on benefit estimation, the key measures and its combinations on soil and water comprehensive control are discussed. At present, the western region is on priority agenda to be invested to rebuild its environment. Therefore, wind-sandy areas should be considered in precedence and also planed as a whole in practice. Otherwise, the western region could not be developed smoothly which will affect the eastern region's economy to be sustainable and steady developing. Researches on comprehensive control of soil and water loss could benefit on reducing soil and water loss and resuming vegetations in the region.
