摘要: 造成湖北省长湖水生植物多样性显著下降的大规模围网养殖于2016年被全部拆除,2018年8月初对长湖圆心湖区的水生植物进行了调查。结果鉴定出了水生植物27种,其中挺水植物、漂浮植物和沉水植物分别为9、8和7种,浮叶植物只有3种;现有群丛9个,生物量为53.52~2 407.71 g/m2,其中穗状狐尾藻群丛达2 407.71 g/m2,多样性指数较高的是茭白+菱群丛和穗状狐尾藻+菱群丛,其Shannon-Wiener物种多样性指数(H′)和Simpson物种多样性指数(D)分别为1.870、0.680和1.844、0.815。与长湖1985—2015年的调查数据比较可见,大规模养殖围网的拆除对长湖水生植物的多样性和群落结构的改善有较好的促进作用,长湖生态在逐步恢复之中。

Abstract: Based on the large-scale breeding seine caused of the significantly aquatic plant diversity reduction in Chang lake were all removed at 2016, the aquatic plants in Yuanxinhu area of Chang lake were investigated in early August, 2018. The results showed that 27 species of aquatic plants were identified including nine emerged plants, eight floating plants, seven submerged plants and three floating-leaf plants. Biomass of species is ranged from 53.52 g/m2Eichhornia crassipes Ass.) to 2407.71 g/m2Myriophyllum spicatum Ass.) in nine existing associations. The Zizania latifolia+Trapa natans Ass. and the Myriophyllum spicatum+Trapa natans Ass. possessed the higher Shannon-Wiener species diversity indices(H′) and Simpson species diversity indices(D),their H′ and D was 1.870, 0.680 and 1.844, 0.815 respectively. Compared with the previous results and data of Chang lake from 1985 to 2015, the demolition of large-scale enclosure culture has a good promoting effect on the improvement of the diversity and community structure of the living aquatic plants of Chang lake, and the ecology of Chang lake is gradually recovering.

Key words: enclosure culture, aquatic plant, diversity, Chang lake
