摘　　要：为了给绰斯甲水电站影响区植物多样性保护和利用提供一定的理论依据,在对该区种子植物进行详细调查、标本采集鉴定的基础上,对其区系进行了统计分析和评价,并与其他类似区域进行比较。结果表明:影响区内种子植物较丰富,共88科、343属、898种;生长型相对单一,以草本植物占绝大多数;大科、大属优势明显;区系特征温带成分占优势,具有从热带向温带过渡的性质;起源较为古老,特有属种较丰富;其生境复杂程度均比官地电站、龙洞电站、十里铺电站高,区系丰富度最大。The specimens of seed plants in the impact zone of Chuosijia Hydropower Station were investigated,collected and identified in detail,the flora characteristics of seed plants were statistically analyzed and evaluated and its relationships with other similar areas were compared to provide theoretical basis for protection and utilization of plant diversity in the impact zone of Chuosijia Hydropower Station.The results showed that the taxa of seed plants were abundant,including 898 species,which belonged to 88 families and 343 genera.The life style was relatively single,most of which was herb.The dominant families and genera were prominent.The transitional characteristic was obvious.The temperate components were dominant,and the tropical components also owned a large proportion.The origin of this flora was ancient and peculiar genera and species were abundant.The geographical components of Chuosijia Hydropower Station were more complex than that of Guandi Hydropower Station,Longdong Hydropower Station and Shilipu Hydropower Station,and the flora was the most abundant.
