摘    要:2007年对宁夏中卫市香山地区的砂田进行了有关生态效应研究.结果表明,砂田具有明显的保墒、增温、减蒸、减尘效果,在4--6月期间,砂田0~40cm土层中土壤含水量比裸田提高32.5%,砂层下地表蒸发量减少28.7%,0~20cm土壤平均每天增温0.96℃,地表以上1.5m高度减少扬尘量43.9%.

关 键 词:砂田  生态效应  保护性耕作

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 %.
Keywords:sandy-field  ecological effection  protecting tillage
