Countermeasure research on black earth wind erosion factor and sustainable use

Black earth is a well -known grain producing area in China. During these decades, water loss and soil erosion is getting worse and worse gradually, soil is getting thinner and thinner, soil capability drops, reduction on grain production is severe. The research focuses on dry arable black land in XingAn alliance, through field test on wind erosion factors in this area (wind speed, temperature, relative humility, blown wind speed), the daily variation of wind speed, temperature, air humility, and its effect on wind erosion are analyzed, the sand transporting volume in wind erosion process is calculated. Through field investigation in spring wind erosion season, sustainable use countermeasures on wind erosion resistance and land degradation in black dry arable soil is, which will provide foundation on sustainable development of black soil grain production in China.
