Wind erosion is a natural phenomenon that has been increasing due to anthropogenic activities. Wind erosion has detrimental consequences on the environment, and its prevention is a critical issue in many arid regions of the world. The topic of this study was an artificial formation of biocrusts to diminish wind erosion by inoculation of the aeolian sand by two filamentous cyanobacteria of Nostoc punctiforme and Microcoleus vaginatus. The erodibility of the sand was examined in a wind–tunnel equipped with a sand particle counter (SPC). The erosion rate, number of emitted particles, and flux of eroded mass from the surface of the sand were measured as indicators of the erodibility at five wind velocities of 6, 10, 15, 20, and 25 m/s. Results suggested that biocrust of M. vaginatus had thicker interparticle bonding and more resistance than biocrust of N. punctiforme against wind erosion; however, both of cyanobacterial crust reduced the erodibility indicators by two to three orders of magnitude.

利用蓝藻接种风沙控制风蚀

风蚀是由于人为活动而增加的自然现象。风蚀对环境有不利影响，在世界许多干旱地区，风蚀的预防是一个关键问题。这项研究的主题是通过两个丝状蓝藻的人工形成biocrusts通过风积沙的接种减退风蚀的点形念珠藻和Microcoleus vaginatus。在配备有沙粒计数器（SPC）的风洞中检查了沙粒的侵蚀性。测量了六种风速（分别为6、10、15、20和25 m / s）下的侵蚀速率，散发的颗粒数量和从砂表面侵蚀的质量通量，作为可蚀性的指标。结果表明生物外壳阴道分枝杆菌比点状猪笼草的生物结壳具有更强的颗粒间结合力和更强的抗风蚀能力。然而，两个蓝细菌外壳都将可蚀性指标降低了两个到三个数量级。
