Plants play an important role in fishpond littorals, but little is known about factors influencing their presence and growth patterns. We surveyed vegetation of reed bed and exposed bottom zones in ponds used for rearing of common carp fry (nursery pond) and ongrowing to market size (main pond). Plant species diversity and functional diversity and plant species cover and functional cover were assessed. We found no significant differences in spring and summer surveys. When data of the analysed vegetation zones were combined, nursery and main ponds showed significant differences in plant species diversity and species cover. Analysis of the vegetation zones revealed that (i) regardless of fishpond management type, exposed bottoms and reed beds significantly differed in plant species cover and functional cover; (ii) plant species diversity and species cover of exposed bottom zones differed between nursery and main ponds; and (iii) no assessed characteristics differed significantly between nursery pond reed bed and main pond reed bed zones. Zone width and shoreline slope exerted greatest impact on development of reed beds, whereas fishpond management type and surrounding land use were the most important factors determining vegetation of exposed bottoms. Partial summer drainage supported plant species diversity and functional diversity as well as cover of typical species of reed beds and exposed bottoms in both fishpond types. Our results are applicable to preservation of fishpond biodiversity as well as to the management and conservation of other shallow water bodies.

两种鱼塘管理类型的生态植被植物物种组成的驱动因素

植物在鱼塘沿海地区起着重要作用,但对影响其存在和生长方式的因素知之甚少。我们调查了池塘中芦苇床的植被和裸露的底部区域,这些池塘用于养育鲤鱼苗(养鱼池)并生长到市场规模(主池塘)。评估了植物物种多样性和功能多样性以及植物物种覆盖率和功能覆盖率。我们在春季和夏季调查中没有发现显着差异。当结合所分析的植被带的数据时,苗圃和主要池塘在植物物种多样性和物种覆盖率上显示出显着差异。对植被带的分析表明:(i)不论鱼塘管理类型如何,裸露的底部和芦苇床在植物物种覆盖和功能覆盖方面均存在显着差异;(ii)苗圃和主要池塘之间裸露的底部区域的植物物种多样性和物种覆盖率有所不同;(iii)育苗池芦苇床区和主池塘芦苇床区之间的评估特征无显着差异。区域宽度和海岸线坡度对芦苇床的发展影响最大,而鱼塘管理类型和周围土地利用是决定裸露底植被的最重要因素。夏季的部分排水支持了两种鱼塘类型中植物的物种多样性和功能多样性,以及典型的芦苇床和裸露的底部物种的覆盖。我们的结果适用于鱼塘生物多样性的保护以及其他浅水水体的管理和保护。(iii)育苗池芦苇床区和主池塘芦苇床区之间的评估特征无显着差异。区域宽度和海岸线坡度对芦苇床的发展影响最大,而鱼塘管理类型和周围土地利用是决定裸露底植被的最重要因素。夏季的部分排水支持了两种鱼塘类型中植物的物种多样性和功能多样性,以及典型的芦苇床和裸露的底部物种的覆盖。我们的结果适用于鱼塘生物多样性的保护以及其他浅水水体的管理和保护。(iii)育苗池芦苇床区和主池塘芦苇床区之间的评估特征无显着差异。区域宽度和海岸线坡度对芦苇床的发展影响最大,而鱼塘管理类型和周围土地利用是决定裸露底植被的最重要因素。夏季的部分排水支持了两种鱼塘类型中植物的物种多样性和功能多样性,以及典型的芦苇床和裸露的底部物种的覆盖。我们的结果适用于鱼塘生物多样性的保护以及其他浅水水体的管理和保护。而鱼塘管理类型和周围土地利用是决定裸露底部植被的最重要因素。夏季的部分排水支持了两种鱼塘类型中植物的物种多样性和功能多样性,以及典型的芦苇床和裸露的底部物种的覆盖。我们的结果适用于鱼塘生物多样性的保护以及其他浅水水体的管理和保护。而鱼塘管理类型和周围土地利用是决定裸露底部植被的最重要因素。夏季的部分排水支持了两种鱼塘类型中植物的物种多样性和功能多样性,以及典型的芦苇床和裸露的底部物种的覆盖。我们的结果适用于鱼塘生物多样性的保护以及其他浅水水体的管理和保护。
