Urban Green land Technology of Ecologically Fragile Regions in Northwest China

Based on the ecological theory and aesthetic characteristic,combining with the actual situation of ecologically fragile regions in Northwest China,and following the principles of acceptable tree species in local soil and ecological environment,outstanding regional characteristic,combined microcosmic and macroscopic aspects,and facilities for water saving,this paper systematically proposed the ecological greening technologies with various levels of structure,complicated construct,ecological diversity,improvement functions integrated with arbor,shrub and grass.It aimed to realize the better recycle of ecology and the sustainable development of urban in Northwest.
