| 8. | It as suggested that management should be strengthened to ensure a better effect in applying these measures to further improve ecological environment 根据各地的具体环境和条件,可以单独或配套使用这些措施,以达到控制风蚀的目的;同时,应加强管理,使这些措施发挥其应有的作用,以便进一步改善环境。 |
| 9. | Based on the formation mechanisms of and erosion and some important research results , this paper reviewed the biological , chemical , and mechanical measures in wind erosion control , which could be applied individually or integrated together to decrease or prevent wind erosion 从风蚀的形成机制出发,按性质将控制风蚀的措施分为生物措施、化学措施和机械措施,并简要论述了这些防治风蚀的措施和一些重要结论。 |
| 10. | However , in observing natural wind erosion , because of the limitation of several factors , such as time , wind power , and the surface of land , it is difficult to take systematic and deeper research , es pecially to complete the research on the regularity of soil wind erosion in a short period 但是,自然风蚀的观测受到时间、风力、地表等多种因素局限,难以进行系统的、深入的研究,特别是在短时期内完成土壤风蚀规律性的研究。 |
