植被毯措施对黑土农田浅沟侵蚀防护效果的研究
Study on the Protective Effect of Vegetation Blanket on Ephemeral Gullies in Black Soil Farmland
为了探究植被毯在植被恢复早期的浅沟侵蚀防护效果,并为黑土农田浅沟治理提供科学依据。以黑土耕作层土壤为研究对象,通过室内模拟汇流冲刷试验,定量分析了植被毯在不同汇流强度下对农田浅沟侵蚀产流产沙的影响。实验结果显示:在小于 30 L/min汇流强度时,植被毯措施可减少 16.23%的径流和 80%以上的产沙。当汇流强度增大到 40 L/min时,植被毯措施减沙效益由 82.19%下降到 26.63%,而减流效益由 15.74%减少到 1.63%,基本…查看全部>>
In order to explore the protective effect of vegetation blanket on ephemeral gully erosion in the early stage of vegetation restoration.And to provide scientific basis for ephemeral gully control of black soil farmland.This paper takes the typical black soil magnetism of Heilongjiang province as the research object,through the indoor simulated confluence erosion experiment,the effect of vegetation blanket on runoff and sediment yield of farmland ephemeral gu…查看全部>>
