英文摘要	In this paper, experimental and numerical studies have been carried out in the design of the checkerboard sand barrier belt (CSBB) in anti-desertification project. Field observations show that the dune speed after CSBB was significantly reduced when checkerboard sand barriers were laid. The closer to the edge of CSBB, the more obvious the decrease of dune speed after CSBB is, the reduction rate of propagation speed of the edge of desertified land (delta = 1 - v/v(no), here, v is the propagation speed of the edge of desertified land with CSBB, v(no) is the propagation speed of the edge of desertified land without CSBB) is about 0.7 at 200 m after CSBB. When the width and spacing are respectively 400 m and 700 m, CSBB can achieve the full paving effect, which confirms the effectiveness of the laying scheme of strip patterns (SP) proposed by Bo and Zheng (2013). Based on the model proposed by Bo and Zheng (2013), the optimal sizes of the spacing and width of CSBB (S-max and W-0) were found, and the expression of degradation length (DL) of CSBB with time, annual wind regime and wind speed is given. Moreover, a laying method for CSBB is given, i.e., the width (W) and spacing (S) of CSBB should satisfy W>DL + W-0 and S
