In order to provide the autonomous regions with better management of desert, irrigation, grasses, we have carried out in the fine river sand area for many years, irrigation, grass selection and introduction, the preliminary results are reported below. First, the sand profile Jinghe sand area is located in the southwestern margin of Junggar Basin, east of Jinghe County, 219 meters above sea level (sand spring child). Climatic characteristics, the continental climate is extremely significant, cold in winter, hot in summer, dry in the air, scarce precipitation, strong evaporation, strong winds. The annual average temperature of 7.9 ℃, the absolute maximum temperature of 42.3 ℃, the absolute minimum temperature of -33.1 ℃, frost-free period of 180 days or more. The average annual relative humidity is 61% and the absolute humidity is 7.4 mbar. The average annual precipitation is 93.7 millimeters a year
