黄河下游防洪工程生物防护措施研究

Biologic Protective Measures in the Control Flood Engineering of Lower Reaches of the Yellow River

黄河下游以临河防浪林为主体的生物防护措施历史悠久，在黄河防洪体系中占有重要位置。但由于临河防浪林宽度一般只有7m左右，堤坡草皮老化严重，且得不到及时复壮，导致覆盖率逐年下降，防浪防冲、护坡作用差。针对山东黄河实际，建议在临河建设30～50m宽的防浪林，堤坡植草防护。

Along the river planted floodproof trees as the main bio-protective measures have along history. It takes an important role in control flood of the Yellow River. However, thesefloodproof trees generally wide 7.0m. The dam slope grass-covery declined severly, and haslower slope protection. Based on the realizal situation of Shandong reaches of the Yellow River. It is suggested that the width of floodproof trees must be 30~50m, and planted grass atslope dam to protect it.
