The invention discloses a design method of an ecological bank protection hydro-fluctuation belt plant population. The design method comprises the following steps: dividing a river and lake slope into three gradients, namely an underwater slope protection area, a hydro-fluctuation belt slope protection area and a bank protection slope area from bottom to top; and then, sequentially selecting perennial herbaceous plants which are resistant to deep flooding, longest in flooding-resistant period and resistant to barren, perennial wetland herbaceous plants which are long in flooding-resistant period and wetland shrub plants which are short in flooding-resistant time and flooding depth as restoration plants of all areas. According to the method, ecological restoration is performed on the hydro- fluctuation belt bank slope with high water level fall and long waterflooding stress in the type of summer-abundance and winter-shortage by analyzing the growth law, growth characteristics and tolerance of plants and combining the engineering technology, the purposes of restoring the ecology of the hydro-fluctuation belt, beautifying the landscape and reducing water and soil loss are achieved, the ecological restoration effect is good, the green restoration speed is high, and the application range is wide.

本发明公开一种生态护岸消落带植物群种的设计方法，将河湖边坡由下而上划分为水下护坡区、消落带护坡区及护岸坡区三个坡度，然后依次选取耐深淹、耐淹期最长且耐贫瘠的多年生草本植物、耐淹期较长的多年生湿地草本植物和耐淹水时间、淹深较短的湿地灌木植物作为各区域的修复植物。本发明通过对植物生长规律、生长特性和耐性的分析，结合工程技术对“夏丰冬枯”型高水位落差、长淹水胁迫的消落带岸坡进行生态修复，达到恢复消落带生态、美化景观、减少水土流失的目的，生态修复效果好，复绿速度快，适用范围广。
