摘 要：
土壤风蚀是我国北方干旱、半干旱以及部分半湿润地区土地退化的主要原因之一,风是引起土壤风蚀的最直接动力,对土壤风蚀的研究需要测量大气边界层近地表的风速廓线。为此,针对现有的风速廓线仪在野外测试中存在的缺陷和不足,研制出了针对土壤风蚀测试的便携式近地表风速廓线仪。该廓线仪采用了抗风沙的楔形热膜风速传感器,采用低功耗的无线网络数据传输方案。经过风洞校准和野外的测试试验,证明研制的风速廓线仪携带方便、抗风沙能力强,能够精确地测量近地表的风速廓线。

摘 要：
Wind is the most direct power to cause soil erosion,and wind erosion is one of the main reasons of arid and semi-arid land degradation as well as part of the semi-humid areas in north China.For better study of wind erosion,near-surface wind profile of the atmospheric boundary layer must be accurately measured.In this paper,due to the shortcomings and deficiencies of the existing wind profilers in the field test,a portable near-surface wind profiler was developed for wind erosion test.What's more,the anti-sand wedge hot-film wind speed sensor and a low-power wireless network data transmission method are designed in the profiler.After calibration in wind tunnel,the field tests prove that the wind profiler is portable,anti-sand ability,capable of accurate measurement of the near-surface wind profile.
