摘  要：
以土地沙漠化迅速发展的河北坝上康保县为研究区域,选取典型的风蚀农田小麦留茬地、莜麦留茬地及翻耕地作为样地,采用野外实地调查和遥感影像解译,总结康保县20余年土地利用空间分布特征,分析风蚀农田分布空间格局动态变化规律。研究表明,旱作风蚀农田主要分布在南部波状平原区和东部缓坡丘陵区,面积降幅较为明显;同时分析地表空气动力学粗糙度及风蚀强度对风蚀的影响,风蚀季节多发在农作物收获后至来年春季播种前。由于耕地不断减少,康保县主要风蚀农田作物小麦和莜麦的种植面积呈减少趋势。

摘  要：
Taking kangbao county in Bashang of Hebei province where soil desertification was developing fast as the investigation region,and typical wind erosion farmland,wheat stubble field,naked oak stubble field and plowed land as sample lands,field survey and romote sensing image interpretation was conducted to sum up the spatial-temporal dynamic characteristics of farmland use over 20 years in kangbao county.The investigation revealed that dry cultivation wind erosion farmland mainly distributed in the southern wavy plain and eastern gentle slopes where the decrease of farmland area was obvious.The effects of earth surface aerodynamic roughness and wind strength on wind erosion were also studied.The wind erosion season often occurred after the harvest of the crop to the following spring before sowing.Due to the decreasing of farmland,the planting area of the main wind erosion farmland crops,wheat and naked oak was decreasing.
