河道植物护坡及水土流失观测

Vegetation Protection for Riverbanks and Its Soil Erosion Observation

植物措施因其固土护坡、生态保护功能,被广泛应用于河道整治工程中。介绍了研究课题的试点工程及水土保持功能观测情况,总结了河道坡岸在植物措施实施各阶段的水土流失特点。对植物护坡的内涵及其水土保持功能的作用机理进行了初步分析,对几种能够用于河道坡岸水土流失观测的方法及适用条件进行了讨论,最后对利用植物措施治理河道研究做了展望。

Vegetation measures are widely applied in slope protection for riverbanks. On the basis of analysis on the mechanism of how vegetation helps to protect riverbanks, the paper discussed the necessity of this measure in modern river training. And the characteristics of soil erosion and water loss and the ohservation of riverbanks stabilized by vegetation are reviewed. At last, the perspectives of vegetation community construction and its eco-hydrology effects are proposed.
