摘　　要：[目的]探讨石羊河下游干旱荒漠区白刺资源特征。[方法]采用线路调查和样地调查方法,确定白刺分布的种类、类型、面积和特点,绘制白刺分布图,并测定果实和种子的性状指标。[结果]经鉴定,该地区白刺分布的种类有泡果白刺(N.sphaerocarpa Maximow-icz)、白刺(N.tangutorum Bobrov)、大白刺(N.roborowskii Komarov)、小果白刺(N.sibirica Pallas)4种,分布类型有草地型、沙丘型、沙地型和散生型白刺4种,主要以沙丘型白刺类型分布在民勤绿洲边缘的西北风沙线上,其分布带约45°,与来自巴丹吉林沙漠的主风方向相垂直,阻挡着风沙危害。[结论]白刺属植物种间变异较大,体现出大白刺具有良好的经济性状,应加强优良品种的选育。[Objective] The research aimed to research the resources characteristics of Nitraria in arid desert area of Lower reaches of Shiyang River.[Method] Using the method of route survey and sampling survey,the distribution species,type,area and characteristic of Nitraria,were determined,the distribution map of Nitraria was drawed and the traits of fruit and seed were determined.[Result] After identification,the area distribution of the species are： Nitraria resources types of N.sphaerocarpa Maximowicz、N.Tangutorum Bobrov、N.roborowskii Komarov、N.sibirica Pallas,types of Grassland Nitraria,Dune Nitraria,Sandy Nitraria and Scattered Nitraria,mainly in the dune Nitraria type distribution in Minqin Oasis fringe of Northwest sandy line,Nitraria Distribution zone with approximately 45 DEG,and from Badan Jilin desert wind direction perpendicular to the principal,Stop the harm of sand blown by wind.[Conclusion] As a result of Nitraria interspecific variation in larger,manifesting the N.roborowskii Komarov has good economic character,should strengthen the breeding.
