| Abstract: | Study on sandy-field ecosystem effection was carried in Zhongwei Xiangshan aera of Ningxia in 2007. The result showed that sandy-field had an obvious effect on keeping soil water, heightening temperature, reducing evaporation and dust ; Between April and June, the water content in 0~40 cm of sandy-field was increased by 32. 5% than naked land and the soil water evaporation in surface under sandy-field is reduced by 28.7% than in naked land, the soil temperature in 0- 20 cm in sandy-field was increased by 0. 96 ℃, the content of dust in the surface above 1.5 m was reduced by 43.9 %. |
