本监测在会泽县的飞播草地上进行,通过设置飞播草地和非飞播草地水土流失监测小区,对飞播种草治理我省滇东北地区水土流失的效果进行了对比研究。监测结果表明,通过飞播种草后,草地植被覆盖率由58%提高到95%;飞播后草地平均地表径流由飞播前的13434kg/hm2减少到10008kg/hm2,减少了25.5%;平均土壤流失量由飞播前的8425kg/hm2减少到842kg/hm2,减少了90%。飞播草地具有较强的水源涵养能力,对改善生态环境,恢复生产和生态功能,遏制水土流失发挥显著作用。
The monitoring was carried out on the fly sowing meadow in Huize County by comparing the monitoring plots of the soil and water loss in the air sowing grassland and the non-grass sowing grassland with the soil erosion in northeastern Yunnan and Yunnan Province. The monitoring results showed that the coverage of grassland vegetation increased from 58% to 95% after the seeding of seeding grassland. The average surface runoff of grassland decreased from 13434kg / hm2 to 10008kg / hm2 before aerial seeding, decreasing by 25.5% From 8425kg / hm2 before flightcasting to 842kg / hm2, a decrease of 90%. The airborne grassland has strong water conservation capacity and plays a significant role in improving the ecological environment, restoring production and ecological functions, and preventing soil and water loss.
