图2. 各风蚀坑贴地表气流观测的测点布置
(a)风蚀坑B1进行了1次观测，布置测点共20处；(b)风蚀坑B2进行了3次观测，共布置测点34处；(c)风蚀坑B3进行了2次观测，共布置测点28处；(d)风蚀坑B4进行了4次测量，其中测量三与测量四部分点测量位置相同，实际测量部位63处；剔除传感出错仪器并进行数据筛选后，部分测点(图中未标明编号的测点)被排除，最终用于本研究的测点有：风蚀坑B1 18个；风蚀坑B2 27个，测量三未参与分析；风蚀坑B3 26个；风蚀坑B4 48个，测量四未参与分析

Fig.2. Array of the measurement of the near surface air flow
(a) One measurement was made at B1 with 20 locations, (b) Three measurements were made at B2 with 34 locations, (c) Two measurements were made at B3 with 28 locations, (d) Four measurements were made at B4 with 63 locations, among which some measurement positions of the third measurement and the fourth measurement were the same. After removing the instrument data with sensor error and performing data screening, some stations that were not labeled in the picture being excluded from analysis. A total of 18 stations in blowout B1, 27 stations in blowout B2, 26 stations in blowout B3, 48 stations in blowout B4 passed the quality control and were used in this study, the third measurement data in blowout B2 and the fourth measurement data in blowout B4 were not involved in this paper
