我场位于哈密盆地、巴里坤山南麓的洪积——冲积扇缘地带,拔海750—800米,坡降4—7/1,000,小地形高差达8—12/1,000。场内原来高包密布,最大的土方量达15,000—30,000方,小的也有300—500方,开荒造田平地工作量很大。地下水埋深1.2—1.5米,水质弱矿化,由于风大、干旱,蒸发强烈,地表大量积盐。土壤以硫酸盐土为主,大部分布在扇缘稍高台地上,植被(芦苇、白剌、骆驼剌等)矮小,复盖度约20％;盐结皮层2—3厘米,其下为20—30厘米的粉状芒硝、食盐结晶和粉状土粒相混合的疏松层,再下为厚数厘米至10厘米的芒硝结晶层,间有少量土粒。底土潮溼,
The site is located in the alluvial-alluvial fan margin at the southern foot of the Hami Basin and Balikun Mountain. It is 750-800 meters above sea level and has a gradient of 4-7 / 1,000 and a small terrain elevation of 8-12 / 1,000. The original high-density package, the largest earth volume of 15,000-30,000 square, there are also small 300-500 square, land reclamation work a lot of land. Groundwater depth of 1.2-1.5 meters, weak mineralization of water quality, due to the wind, drought, strong evaporation, a large number of surface salt accumulation. Soil mainly sulfate soil, most of the cloth in the fan margin slightly higher platform, vegetation (reed, white assassination, camel assassination, etc.) short, covering about 20%; salt crust 2-3 cm, which is 20- 30 cm of powder thenardite, salt crystals and powdered soil particles mixed loose layer, and then a few centimeters thick to 10 cm Glauber salt crystal layer, a small amount of soil between. Subsoil wet,
