%X The saline land is a kind of important reserved cultivable land resource in China. In this process of the study, when digging gutter to reduce underground water level to the level less than critical level, we have used the comprehensive measures of farming, forestry and animal husbandry and have built a systematization pattern for transformation and utilization of saline land in arid areas. A set of controlling techniques for saline land was put forward, it includes digging gutter and afforestation to control underground water level lower than critical level,selecting salt tolerant crops to improve alkaline soil, and developing animal busbandry to build up fertilizer.Then we practised it on the saline land in Xiaoquanzi of Linze County. As was expected, the salinity in the soil decreased and the organic matter in the soil increased. As a result, the land productivity was improved highly and there was a notable economic benefit.
