摘要
简述了目前生态型河道的现状,发现在河道中种植植被能很好的净化水质,不同的植被净化的能力不一样;同时也总结了前人对有植被河道水流特性研究的成果,发现种植不同种类的植被、按不同种植方式、在不同位置种植,对水流特性的影响是不同的。所以研究生态型河道时,考虑植物对水质的净化作用的同时也应研究河道水力特性的变化,为实际工程提供参考。
The status of ecological watercourse nowadays is described in the paper and a discovery is that water plant can absorb the infectant and purify the water in different purifying efficiency. The achievement of the pre-study of hydrodynamic behavior in vegetated flow is summed up. Different species, planting mode or position of hydrophyte has different effect to the water flow. When the ecological watercourse is studied, the effect of purifying and hydrodynamic behavior should be combined.
