摘要
通过实地调查和查阅近200篇国内外文献,对新疆绿洲防护林体系的营建、树种选择、配置模式、灌溉历程的发展动态进行了分析和研究,同时也对新疆绿洲防护林树种选择、配置模式的发展方向,以及改用节水灌溉后防护林体系地表水文发生的改变进行了探讨。结果表示:新疆大规模的绿洲防护林营建历史悠久,始于20世纪50年代;新疆绿洲防护林树种选择由单一化向多林种转变,配置也由单一化的"宽林带、大网格"模式向乔、灌、草结合,形成时间上有序、空间上有层次的"窄林带、小网格"模式;大水漫灌、沟灌、串畦淹灌等传统的防护林灌溉方式被微滴灌所代替后,使防护林地表水文发生变化,所以提倡西北干旱区不该大力推广微滴灌技术,而应有所限制地使用。
The developmental course of the contruction, the selection of tree species, the configuration mode and the irrigation history in Xinjiang oasis shelter belt system were summarized, then comeing to the conclusion： the shelter belt in Xinjiang has the centuries - old construction history ; the single ecotypic shelter belt in history has been turned into the economical shelter belt, and has the polytype tree species; the single configuration mode of shelter belt in history has been turned into zonal or plate - like shelter belt today, and integrated the arbor, the shrub, the flower and the grass; the irrigation of shelter belt in history such as flooding , furrow irrigation have been replaced by water - saving irrigation gradually. The selection of tree species, the configuration mode and the influence of watering action on protect forest system after applied the drop irrigation were discussed. To attempt to put forward that the water-saving irrigation should not be used universally, but restrictly, and some of the maintain measures was proposed under the new water- saving control .
