Résumé partiel
On the basis of the available research conducted inside the country, this thesis focused on zoning of the water-saving irrigation areas in Xinjiang, the appropriate development model for each zone, and the relevant issues of adopting gravity sprinkler irrigation in these zones considering the special natural conditions and the current agricultural practices in this arid region. The study results can provide scientific basis for development of water-saving irrigation technique and optimum allocation of water resources in the arid Xinjiang.According the production practice in Xinjiang, this study approach combined data collection with on-site investigation and on-site experiment with theoretical analysis. The research contents have following 5 components : 1) development model of water-saving irrigation technique in arid Xinjiang ; 2) economic analysis and calculations for gravity sprinkler irrigation projects ; 3) crop water requirement, irrigation scheduling and crop water production function ; and 5) fertigation system development and its application experiment. The main findings are as follows:1. Based on the evaluation indexes of climatic characteristic, water shortage, irrigation type and topography of the irrigation districts, 6 water-saving zones were divided for Xinjiang, they are : 1) pumping and storage area of the dry Tu-Ha valley with water shortage ; 2) water diversion and storage area of the dry Kunlun mountain northern side with water shortage ; 3) water diversion, pumping and lifting area of the dry Tianshan mountain southern side with minor water shortage ; 4) water diversion, pumping and storage area of the dry Tianshan mountain northern side with water shortage ;
