Abstract: To get rid of poor pattern of production & living and anomalism all year for most herdsmen, and to limit overloaded depasture for natural grass land and to control degeneration of its ecological environment, Xinjiang Government will launch 27 projects of Settlement for Development of Animal Husbandry within 3year completion. Under the characteristics of short construction period, deficient hydrological data and complicated geological condition of dam construction, the paper shows difficulties and key points of their survey, design and management, and then analyzes three safeguard measures, including settingup project & approval, construction funds, construction management & qualify safety. It presents technical supporting system including dam construction, engineering hydrologic calculation and geological survey, engineering design and construction techniques. It provides major principles of technical measures which should be mastered, such as construction scale by larger instead of smaller, discharge structure scale by smaller instead of larger, earthquakeresistant design by evaluation on Ⅶ degree and design on Ⅷ degree, irrigation mode by area in higher elevation forming natural pressure, complicated geological condition to be kept away and be given up and etc. It establishes technical supporting system of water resources works of settlement for development of animal husbandry. It discusses issues like water resources safeguard in herdsmen settlement and settlement model, auxiliary works construction and management in irrigation zone, water price for water resources works and united water management in settlement area, exploration scale in intake area for water resources works and etc. It points out that three settlement types, including concentrated settlement, scattered settlement and switching on the other production, are suitable for actual situation in Xinjiang instead of largescale exploration of soil and water resources; and at the same time playing function of water resources and their auxiliary works depends on speeding up construction foundation of forage and feedstuff, which is a intensification & modernization development road. Water price of water resources works should consider ability of herdsmen and requirement of operation of works in good condition and it could be put into place stepbystep by financesupporting. United water management in settlement area is carried out for playing project scales function. Scale of settlement area should be committed to balance of soil and water, balance of supply and requirement and prevent small horse with a large cart. After projects are completed, hydrologic monitoring should be strengthened to recheck hydraulic calculation outcomes for providing reliable basis of reservoirs safety in flood period and their regulation. The smooth development of settlement for development of animal husbandry gives deeply scientific connotation of Xinjiang Efficiency, which is for guide and reference for speeding up modern animal husbandry development.

Key words: settlement for development of animal husbandry, grassland ecology, reservoir, water delivery works, technical supporting system
