在太行深山区海拔500～1000m干旱荒坡特定环境条件下,通过深入调查,分析该类型区的自然降水、山石土壤特性、蒸发量及水分循环运行规律,结合荒山开发、绿化建园,设计了适合北方干旱区山旱地果园应用的不渗漏、蒸发量小、能安全蓄水越冬无冻害、水质长期保持不变的高效蓄水设施和与之配套的拦、蓄、输水设施;规划构建了以充分利用自然降水、拦蓄地表迳流与土壤饱和水流为特色,以高效蓄存、自流蓄灌与扬水蓄灌相结合多级回灌为主体的蓄灌体系;阐述了干旱荒坡梯田丰水季节和丰水年份拦蓄自然降水,干旱季节反复利用多级回灌解决山旱地灌溉问题的方法与理论;展示了变干旱荒坡梯田为理想的生态农业区的新途径。
Under the specific environmental conditions of 500-1000m above sea level drought in the deep mountainous area of Taihang, this paper studied the natural precipitation, the characteristics of soil and soil evaporation, the evaporation and the law of water cycle operation in this type of area, combined with the development of barren hills and greening garden Suitable for non-seepage and evaporation with small amount of evaporation in mountain dry land orchards in the northern arid region, high-efficiency water storage facilities with long-term water quality without frost damage and long-lasting safe water storage, and supporting facilities for water storage, storage and transportation; planning and construction In order to take full advantage of natural precipitation, surface water retention and surface soil saturation flow as a feature, with efficient storage, gravity flow storage and combined storage pumping multi-stage irrigation as the main body of the storage system; elaborated the drought barren terrace The method and theory of repeatedly using multi-stage irrigation to solve the problem of dryland irrigation in dry season and wet season, and the new way of changing the dryland-barren terrace into ideal ecological agricultural area.
