Six tree species of ecology-economy shrub including elaeagnus angustifolia L.and Sabina vulgeris were introduced in the windy desert regions of Northern Shanxi.The adaptability of different shrubs was analyzed in the aspects of survival rate,preserving rate,tree height,ground diameter and crown diameter increment,etc.Five suitable shrubs（Sabina vulgeris,Elaeagnus angustifolia L.,Xanthoceras sorbifolia bunge,Forsythia suspense and Lycium barbarum） were preliminary screened.The survival rate of 5 kinds of shrubs in the planting year reached 92% above;the preserving rate in the third years after planting reached 85% above;the tree height annual average of Elaeagnus angustifolia L.,Forsythia suspense and Lycium barbarum reached 40cm.The ground diameter growth of Elaeagnus angustifolia L.is the fastest,about 0.63 cm.And the crown diameter growth of Forsythia suspense is the largest,average 67.0 cm.
