摘    要:由于河西走廊人口增加、单位面积耕地用水量减少、渠道水泥化的发展、防护林病虫害加剧等因素的制约,走廊绿洲小网格杨树防护林、边缘区防风固沙林营造模式已不适应河西绿洲防护林体系发展的要求。杨树易繁殖、速生、成林快、适应性强的特点,在未来一定时期内仍将是本区主要的农防林树种,通过正确利用杨树各树种的生物学特性,依据当地病虫害状况,适时进行树种的更替更新,以防止自然灾害,是防护林更新复壮的基本措施。同时,随着技术的进步,加快防护林林种多样化、区域自然式林业、区域特色的生态经济型防护林、林业生产和生态建设高新技术的开发利用将是未来林业发展的趋势,也是可持续生态环境建设的目标。

关 键 词:河西绿洲  防护林  现状  发展趋势  探讨

Abstract:Under the limited factors of population increasing,irrigation capacity reducing in farmland per unit,concrete water ditch building,serious pest and disease in shelterbelts and so on,the contemporary afforestation models of small-net Populus shelterbelts in oasis and sand-fixation and windbreak forestbelts at the oasis fringes have not been adapted to the developing requirement of oasis shelterbelt system in Hexi Corridor.With the characteristics of easy breeding,fast growth,quick windbreak effect and strong adaptability,Populus species will still be the most important shelterbelt trees in the future,the replacement and regeneration of Populus species by use of their specific biological characteristics in accordance with disease and pest development are the basic steps for the shelterbelt restoration.Mean while,with the technological development, the increasing of shelterbelt species diversity,natural and automatic forest development,featured district eco-economic shelterbelt and hi-tech development and application in forestry production and eco-establishment will be the developing tendency and be the purpose for sustainable eco-environmental development in Hexi Corridor.
Keywords:Hexi Corridor  shelterbelt  contemporary situation  developing tendency
