【Abstract】 This paper analyses the natural resources and social economical con-ditions in the irrigation system in the arid areas of northwest China,and also evaluates that the implementation of the intensive multiple-cropp-ing system is not only possible,but also has historical and realistic evi-dence in irrigation system in the oasis agricultural zone Meanwhile,the comprehensive evaluation of the intensive multiple cropping systemwas carried out in accordance with the results of multiple point experiments and investigation data.It is considered that the intensive multiple-cropping system has a strong ecological adaptation with bettereconomical results and obvious social benefits.Also,the approaches toimplement the intensive multiple cropping system are suggested basedon the existing key problems in crop planting,thus providing a refere-nce for further developing irrigation system and establishing farmlandecological balance of higher layers.更多还原
