Abstract: This thesis approach to the methodology of series study for the land resources, including classification, evaluation, optimization model and carrying capacity of land resources, taking the oasis of the Hutubi County, Xinjiang Uygur Autonomous Region as an example.First, the type of land resources was divided and the system of classification was established. Then, the elementary types of land resources were used as a land mapping unit to evluate the land quality and its suitability. Based on these results and the main natural, ecologic, social and economic conditions affecting land use, the optimization scheme for the utilization of land resources was selected by linear programming through IBM-PC computer. At last, based on the yield levels of the first-class land resources, the population supporting capacity of land was calculated to meet the productive conditions which the optimization scheme should require. That is to calculate how many people could support by one mu or one ha arable land based on the calculation of mean intakes of calorie and protein every member in our country. The calculations, compared with year 1984, demonstrated that population supporting capacity under the optimization scheme of land use will enhance evidently.
