摘要
以江西水土保持生态科技园内布设的不同边坡防护措施小区为研究对象,通过对2016年18个径流小区28次侵蚀性降雨量和各小区径流量、土壤侵蚀量等指标进行测定,分析了不同边坡防护措施小区的保水减沙效益。研究结果表明:边坡防护措施小区相对裸露小区(对照)具有显著的保水减沙效益;在坡比1∶1.5的护坡措施小区中工程措施与生物措施相结合的护坡方式保水减沙效果较好,坡比1∶2的护坡措施小区中等高绿篱埂护坡保水减沙效果最为明显。
The paper analyzed and evaluated the soil and water conservation benefits of different slope protection measures by taking runoff plots with different slope protection measures laid out in Jiangxi soil and water conservation technology zone and through the measurement of 28 erosion rainfall,runoff and soil erosion in 18 runoff plots in 2016.The outcomes show that a)comparing with the bare plot(control),the plots with slope protection measures have significant soil and water conservation benefits;b)in the plots with slope ratio 1 ∶ 1.5 it has better soil and water conservation effect with the combination of engineering measures and ecological measures and;c)in the plots with slope ratio 1 ∶ 2 it has the most obvious soil and water conservation effect through planting contour hedgerow.
