In China, there are many inland rivers in arid zone, and in most desert , they can be found in intermontane basins. Rivers arc divided into interior valleys according to their watershed. Each one can be regarded as an integrated function unit of a closed valley ecosystem. This paper discuses processes of developing the river vally controlling deserts and combating desertification in the Manas Rriver valley on the north slope of the Tian Shan mt.. People there has made the full use of potential of water and land resources within the valley based on characteritics of the valley ecosystem. At first, they made overall planning valley of the according to water resources limits and its condition. Then the efficiency of water resources was made full use on desert ecological balance in the valley through constructing a complete valley water resource system, coordinating use of surface and underground water and mastering irrigation techniques. Moreover it is necessary to establish oases protective system in desert areas, improve soil fertility for raising productivity of land and regulate the structure of agriculture, forestry and animal husbandery. So doing an new ecosystem of artificial irrigation oasis, Shihezi Reclaimed Area is one of the example, has been established.

Owing to shortage of water,draught, poor soil texture and extensive cultivation, the yields in the hilly terrace of Linfeng Area, Shangxi Province have long been neither high nor stable. Hilly terrace covers 40% of the total cultivated lands. Therefore, farm irrigation is urgently required to improve local conditions of agricultural production. According to several years' experiments, the paper makes a comprehensive study on the necessity and feasibility of the development of irrigation in the hilly dryland, on the selection of irrigation technclogies and en cconcmic benefits, the paper also recommends that irrigation primarily aims at pipe supply of water and reservier action. Full use of small local water resources, the application of water-saving irrigation techniques and of limited irrigation are important measures that call for great attention as well.

A mathematical model of water movement in the border irrigation for directing border irrigation technique has been described. By orthogonality analysis, we have reached on optimum combination of technical parameters under two different soil conditions. The effect of individual technical parameter on the irrigating quality index and interaction among the parameters have been analyzed. On this basis, we have drawn respectively the equi-efficiency curves under two different soil conditions. From these curves, the rational range of the values of these parameters have been obtained directly. A diagramatic method for determination of irri-cgating parameters using advance curve and recession curve calculated theoretically has been suggested.
