随着人口增长、社会经济发展和城镇建设步伐的加快,土地利用需求快速增加。河流流城亦受到过度开发。围垦河流洪泛区、河滩和湖泊消落区等重要湿地,严重削弱了问流

生态系统自然调节洪水的能力。传统河流整治工程措施也极大地破坏了河流生态系统。传统的护坡工程将整个河岸表面封闭起来,隔绝了土壤与水体之间的物质交换,原本生长在岸坡上的生物不能继续生存,生态系统的食物链断开,使土壤和水体中的生物失去了赖以生存的环境。传统混凝土河道护坡对生态的影响主要有:①在两岸由水泥石料修葺的河道中,具有净水功能的水生生物生长非常困难,河水自净能力将大为降低,水质恶化;②混凝土砌成的大面积刚性护砌面,由于缺乏透气性、透水性,对温度、湿度的调节性能差。不利于维持水中生态平衡边坡上寸草不生,一片荒芜,特别夏季太阳的直接暴晒,在边坡周边所形成的“热岛效应”,导致了局部气候的恶化,还容易使传染病菌草生;③传统边坡忽略了河道与岸上生态系统的有机联系,使得岸上植物难以生长,鱼类及两栖类动物失去了栖息和繁殖的条件,使水中生物减少,岸上又缺乏天然植物,直接影响沿河生物种类生存。据统计、河道衬砌后,沿河生物种类减少了70%以上,而水生物也只相当于原来的50%。此外,传统的混凝土护坡在施工中均不同程度地使用了一些添加剂,如早强剂、抗冻剂、膨胀剂等,这些添加剂在水中发生反应,对水质和水环境产生不利的影响。岸坡没有天然植物作为屏障,会使岸边的垃圾轻易入水,造成污染。这些虽然不是水质恶化的主要原因,但它们对水质的恶化起到了促进作用。同时,没有绿色的传统护坡使河道失去了原有的生机,这与现代人们追求回归自然的要求不相一致,与建立优美环境相违背,更与人文景观不相和谐。With the population growth, socio-economic development and the acceleration of urban construction, the demand for land use increases rapidly. River cities are also over developed. Reclamation of important wetlands such as river floodplain, river beach and lake drawdown area has seriously weakened the cross flow

The ability of ecosystems to naturally regulate floods. Traditional river regulation engineering measures have also greatly damaged the river ecosystem. The traditional slope protection project closes the whole river bank surface and isolates the material exchange between soil and water. The organisms originally growing on the bank slope can not continue to survive, and the food chain of the ecosystem is disconnected, which makes the organisms in soil and water lose their living environment. The ecological impact of traditional concrete river slope protection is mainly as follows: ① in the river repaired by cement and stone on both banks, the growth of aquatic organisms with water purification function is very difficult, the self purification capacity of the river will be greatly reduced and the water quality will deteriorate; ② Due to the lack of air permeability and water permeability, the large-area rigid masonry surface made of concrete has poor regulation performance of temperature and humidity. It is not conducive to maintaining the ecological balance in the water. There is no grass on the slope and it is desolate. In particular, the "heat island effect" formed around the slope due to the direct exposure of the sun in summer leads to the deterioration of local climate and the grass growth of infectious bacteria; ③ The traditional slope ignores the organic connection between the river channel and the shore ecosystem, which makes it difficult for the plants on the shore to grow, the fish and amphibians lose their habitat and reproduction conditions, resulting in the reduction of aquatic organisms, and the lack of natural plants on the shore, which directly affects the survival of biological species along the river. According to statistics, after the river lining, the biological species along the river have been reduced by more than 70%, while the aquatic organisms are only equivalent to the original 50%. In addition, some additives are used in the construction of traditional concrete slope protection to varying degrees, such as early strength agent, antifreeze agent, expansion agent, etc. these additives react in water and have an adverse impact on water quality and water environment. There are no natural plants on the bank slope as a barrier, which will make the garbage on the bank easy to enter the water and cause pollution. Although these are not the main reasons for the deterioration of water quality, they have promoted the deterioration of water quality. At the same time, the traditional slope protection without green makes the river lose its original vitality, which is inconsistent with the requirements of modern people's pursuit of returning to nature, contrary to the establishment of a beautiful environment, and disharmonious with the cultural landscape.
