Biological crust rainwater collecting surface for collecting and purifying rainfall runoff in arid region and application of biological crust rainwater collecting surface
The invention relates to the field of ecological environment management, in particular to a biological crust rainwater collecting surface for collecting and purifying rainfall runoff in an arid region and application of the biological crust rainwater collecting surface. The biological crust rainwater collecting surface is obtained by transplanting or inoculating naturally-collected biological crust of which the surface thickness is 10-30mm and the coverage degree is greater than or equal to 40% to an exposed slope and then culturing; the biological crust is typical moss crust and/or blue-green algae crust formed by natural development in a drought environment; the longitudinal gradient of the slope is greater than or equal to 1/50; full-time shading culture is adopted in the first 3-4 weeks of culture, and the shading rate is 60-80%. The biological crust rainwater collecting surface provided by the invention can be used for efficiently collecting rainfall, remarkably increasing the rainwater collecting runoff and the rainwater collecting efficiency, improving the water quality and relieving the water pressure of an arid region; meanwhile, the soil erosion caused by runoff can be effectively reduced, and a remarkable water and soil loss prevention and control function is achieved.
本发明涉及生态环境治理领域，尤其涉及一种旱区用于收集净化降雨径流的生物结皮集雨面及其应用。生物结皮集雨面由自然采集的表层厚度为10～30mm、盖度≥40％的生物结皮移植或接种至裸露坡面后培养得到；所述生物结皮为干旱环境下自然发育形成的典型藓结皮和/或蓝藻结皮；坡面的纵向坡度≥1/50；培养的前3～4周采用全时段遮阳培养，遮阳率为60～80％。本发明提供的生物结皮集雨面能高效收集降雨，显著增加集雨径流量和集雨效率，提升水质，缓解旱区用水压力；同时，还能有效降低径流对土壤的冲刷，具有显著的水土流失防治功能。
