【摘要】 选择了岗南水库上游、岗南一黄壁庄水库之间以及黄壁庄水库下游3个典型区段进行了植被调查。研究结果发现,随着离河道上游越来越远,受水量的影响,备采样点的植物种数、物种丰富度和物种多样性均呈不同程度的下降趋势:受人类活动的影响,备区段伴人植物占比呈逐渐增加趋势。针对本区存在的问题,有针对性地提出了增加湿地面积、建设滹沱河林带和人工水景观、加强河道综合管理等一系列恢复措施。更多还原

【Abstract】 The research selected three typical areas for plant investigation,including upper reaches of Gangnan Reservoir,the area between Gangnan and downstream of Huangbizhuang Reservoir,and Huangbizhuang Reservoir.The results showed that affected by water,plant species,species diversity and species richness were all decreasing in varying degrees as the distance with watercourse upper reaches was increasing,but the ratio of Anthropochory plants was growing.The research finally proposed countermeasures,including increasing wetland area,constructing forests and artificial water landscape of Hutuo River and reinforcing watercourse comprehensive management.更多还原
