调查和资料分析认为,引洪漫地是一项费省效宏的措施,它可以改变土壤理化性状和土壤结构,提高土壤肥力,增加土壤水分,达到增加作物产量的目的,而且也能用来压沙压碱,改良农田。通过总结黄土高原地区现有的引洪漫地措施,提出了引洪慢地发展缓慢的原因及对策,探讨了本区发展引洪漫地的必要性和可行性。 According to the survey and data analysis, it is a cost-effective measure to divert floods. It can change the physical and chemical properties of the soil and the structure of the soil, increase soil fertility, increase soil moisture, and increase the yield of crops. It can also be used Pressure sand alkali, improve farmland. By summarizing the existing flood diversion measures in the Loess Plateau, the reasons and countermeasures of slow development of flood diversion are proposed, and the necessity and feasibility of developing flood diversion in this area are discussed.
