摘要: Abstract The rapid and accurate estimation of soil loss by wind erosion still remains challenge. This study presents an improved scheme for estimating the farmland. method estimates based on a comparison relative contents erodible non-erodible particles between surface sub-surface layers farmland ploughed layer after erosion. It is features that particle-size distribution sampling (approximately 2 cm) relatively uniform, layer, causes numbers to decrease increase, respectively. Estimations were performed using this periods (WEP) from Oct. 2012 May 2013 April 2014 large wind-erosion event (WEE) 3, in Bashang area Hebei Province. results showed average was 2852.14 g/m 2 with depth 0.21 cm, while 1199.17 g/m mean 0.08 cm. During severe WEE 2014, 1299.19 g/m 0.10 cm. raked fields (PRF) approximately twice as oat-stubble (OSF). (IPSDC) has several advantages. can not only calculate amount, but also deposition amount. Slight changes thickness particle diameter range will obviously influence results. Furthermore, convenient, rapid, simple implement. suitable or flat surfaces high materials.
