黄河水含沙量大,使引黄灌区在引水的同时也引进了大量泥沙,引黄泥沙既是引黄灌区各种生态环境问题产生的主要根源,也是重要的、有待深入研究开发的自然资源。本文根据对小开河引黄灌区的土壤调查、分析化验与多年工程测试研究等资料,深入分析了通过远距离输沙与浑水灌溉后,引黄入田泥沙对灌区土壤颗粒组成、土壤容重、土壤有机碳及养分状况等方面产生的影响,提出了既有利于引黄泥沙处理,又可以稳定和提高引黄灌区土地质量的具体措施。为引黄灌区合理配置水沙资源,解决灌区引黄泥沙与生态环境恶化问题提供科学依据。
The large amount of sediment in the Yellow River makes the Yellow River Irrigation District also introduce a large amount of sediment while diversion. The Yellow River Sediment is not only the main source of various ecological environmental problems in the Yellow River Irrigation Area but also important to be further studied and developed Resources. Based on the soil survey, analysis and years of engineering test and analysis of the Yellow River irrigated area in Xiaokaihe River, the effects of sediment on the soil particle composition, soil bulk density, Soil organic carbon and nutrient status and other aspects of the impact of proposed not only conducive to the Yellow River sediment treatment, but also to stabilize and improve the quality of the Yellow River Irrigation Area of the concrete measures. It provides a scientific basis for the rational allocation of water and sediment resources in the Yellow River irrigated area and the solution of the sediment drowned in the Yellow River and the worsening of ecological environment.
