荆江河段河岸带植被分布特征及生态护岸植物的筛选

The distribution of vegetation at riparian zone and its screening for ecological riverbank in Jingjiang River

传统的河道护岸大都以硬质材料为主,隔绝了河流与岸坡间的水力联系,带来了河岸带生境条件单一、生物群落多样性减少、生态系统退化等弊端;因此,实行生态护岸是今后护岸工程的发展趋势。文章通过对荆江河段河岸带植物进行了调查,分析了影响河岸带植被分布的主要因素,根据生态适应性、繁殖容易性、水土保持能力、生态安全性原则和经济价值性等原则筛选了可用于荆江河岸生态护岸的典型植被物种,可为荆江河段的生态治理提供参考。

The traditional river revetments are mainly rely on the hard materials, but it cut off the hydraulic connection between the river and bank slope, result in riparian environment simplification, biological community diversity reduction, ecosystem degradation and other defects. Therefore, implementation of ecological revetment is future trends in revetment works. Based on the riparian vegetation investigation, the main factors that affect its distribution are analyzed. According to the principle of ecological adaptability, easy propagation, soil and water conservation capacity, ecological safety and high economic value, several typical vegetation species are screened for the ecological revetment. The study can provide a new reference for the ecological treatment in Jingjiang River
