Abstract:

风力提水灌溉是风能利用的重要方式之一,且节能环保。辽西地区风资源丰富,探讨风力提水灌溉,解决农业干旱缺水问题意义重大。以平均风速、有效风时数、有效风能密度、风速年内变化、年内降水分布、雨水利用率等为评价指标,分析了辽西地区风能资源状况和分布特点,以及降水年内分布和利用情况,风资源分布特点与农业需水之间的关系,探讨了辽西地区发展风力提水灌溉的可行性。并通过应用实践,证明辽西地区发展风力提水灌溉可行,是解决辽西农业干旱问题的有效途径。
Wind water-lifting irrigation is one of the important ways of utilizing wind energy, which is ener-gy-saving and environmentally-friendly. Wind resources are rich in western Liaoning region, and discussing wind water-lifting irrigation to solve the problem of agricultural drought is of great significance. The status of wind energy resources in western Liaoning region, the distribution characteristics, the distribution and utilization of rainfall, and the relation between distribution characteristics and agricultural water demand are analyzed using evaluation indexes of average wind speed, effective wind hours, effective wind energy density, yearly wind speed change, yearly precipitation distribution and rainwater utilization, and the feasibility of wind water-lifting irri-gation in western Liaoning region is also discussed. Meanwhile, the application practice has showed that wind water-lifting irrigation in western Liaoning region is feasible and it is an effective way to solve the problem of agricultural drought in western Liaoning region.
