| Abstract: | The current status of aquatic macrophytes in Lake Dianshan was surveyed from August 2009 to May 2010.The succession tendency of aquatic vegetation and reasons for the diversity loss were discussed.The results showed that the aquatic flora in the Lake Dianshan included 29 species which belong to 25 genera,18 families,now the proportion of cultivated or exotic species was higher than that in the past.The aquatic vegetation,especially submerged vegetation,was shrinking dramatically during the past 30 years.Mai... |
