Influence of diversion power stations on riparian plant communities
along Dicun stream China
Abstract
This article used three diversion power stations with different
operating years along Dicun stream of the source of Jiulong River to
study the riparian plant community and discussed the impact of power
station development on riparian plants. The results showed that:(1)There
were significant differences in the plant diversity of herbs, shrubs and
trees among all sample plots in the study area (P < 0.05).(2)
The species number of the second and third diversion power stations with
longer operation time was larger than that of the fourth diversion power
station with short operation time.(3) The water-borne plants were
concentrated in the herb layer in the influence area of the diversion
power station, and the Richness, Shannon- Wiener, Simpson and Pielou
indexes of water-borne plants in the study area were significantly
different (P < 0.05). (4) The appearance of diversion power
station leaded to the change of environmental factors, and the river
depth and flow rate had significant positive correlation with the
diversity index of riparian plants and water water-borne plants (P
< 0.05). In general, with the increase of the operation time
of the power station, the surrounding riparian plant will form a new
stable community.
