Abstract: To satisfy the water demand for Tarim Basin's economic development in the year 2000, about 33.4×108 m3 water needs to be further tapped. Acco rding t o the analysis of the current status of water utilization, it is pointed out th at, to achieve such economic objectives, the policy of emphasizing both water ex ploitation and water conservation with the preference given to conservation meas ures must be followed. For this end, the potentials of exploring new additional sources and strengthening water conservation have been well analyzed, along with the calculation and tech-economic-assessment of some related parameters like the canal transmission efficiency in water delivery systems and the water irrigation effi ciency in the field. The results indicate the potentials of water resource expan sion and conservation are 34×108 m3 and 57×108 m3, respectively. Bas ed on such rese arch outputs, a water conservation program has been developed for the Tarim Basi n, to provide important references and policy recommendations for the decision- makers in Xinjiang agricultural department to implement water utilization measur es.
