工程型护岸指确定加固处理岸坡方案仅出于防洪、输水和航运等工程需要，将原有岸坡改造为混凝土、砌石等为代表的刚性工程护坡。混凝土、浆砌块石等建筑材料的广泛采用原因是这些材料的抗冲、抗侵蚀性及耐久性好，同时对于输水的人工运河，还可减低糙率，提高输水效率，减少渗透损失。这种结构从传统的工程水利角度来看，是安全、经济和有效的，但它同时也破坏了原有的岸坡自然生态系统及其相应功能，生态型护岸是指确定加固处理岸坡方案时不仅考虑工程的安全、经济和有效性和人的 需要，同时还要考虑生态问题和环境问题，注意保存和增加生物的多样性和食物链的复杂 性，积极为水生动物、两栖动物和昆虫等提供栖息空间。Engineering-type bank protection refers to the determination of the strengthening treatment of the bank slope only for the needs of flood control, water transportation and shipping, and the original natural bank slope is transformed into a rigid engineering slope represented by concrete and stone masonry.The reason for the widespread use of construction materials such as concrete and mortar blocks is that these materials have good impact resistance, erosion resistance and durability. At the same time, for the artificial canals for water delivery, it can also reduce the roughness, improve water delivery efficiency, and reduce seepage loss. .This structure is safe, economical and effective from the perspective of traditional engineering water conservancy, but it also destroys the original natural bank slope ecosystem and its corresponding functions. Ecological bank protection refers to the determination of a strengthening treatment plan for the bank slope Not only consider the safety, economy and effectiveness of the project and human needs, but also consider ecological and environmental issues, pay attention to preserving and increasing biodiversity and the complexity of the food chain, and actively contribute to aquatic animals, amphibians and insects. Provide habitat space.
