摘要:

为评价苏州工业园区水生生物多样性及水生态环境现状，于2022年11月（秋季）与2023年5月（春季）开展苏州工业园区辖区内阳澄湖及周边河湖春、秋季水生生物种群结构和资源状况调查。结果表明，该区域共鉴定出浮游植物7门89种，浮游动物4大类95种，底栖动物3大类59种；春季各调查点位浮游植物、浮游动物和底栖动物密度平均值分别为11.48×10⁶cell/L，2 505.98ind./L，566.95 ind./m²，均大于秋季（5.13×10⁶cell/L，1 237.74 ind./L，382.48 ind./m²）；春季各调查点位浮游植物、浮游动物和底栖动物生物量均值分别为5.48，1.11 mg/L，461.31 g/m²，同样均高于秋季（1.27，0.99 mg/L，190.21 g/m²）。香农-维纳（Shannon-Wiener）多样性指数（H′）和皮耶罗（Pielou）均匀度指数（J）结果表明，园区水生生物多样性处于较好至丰富，种间个体分布均匀度处于良好至优秀水平，其中秋季浮游植物和底栖动物的多样性指数较春季有较大降低。总体而言，由于沉水植物分布、温度差异等原因，园区水生生物分布呈现出一定的时空差异；部分水域呈现出一定程度的富营养化，仍需进一步强化监测预警。

Abstract:

To evaluate the aquatic biodiversity and aquatic ecological environment status of Suzhou Industrial Park， a survey was conducted in November 2022（autumn） and May 2023（spring） to investigate the population structure and resource of aquatic organisms in Yangcheng Lake and surrounding rivers and lakes within the Suzhou Industrial Park in spring and autumn. The aim was to evaluate the aquatic biodiversity and aquatic ecological environment status of the area. The analysis results show that a total of 89 species from 7 phyla of phytoplankton， 95 species from 4 major categories of zooplankton， and 59 species from 3 major categories of benthic animals have been identified in the region； The average distribution density of phytoplankton， zooplankton， and benthic animals at each survey site in spring is 11.48×10⁶cell/L， 2 505.98 ind./L， 566.95 ind./m²， respectively， which is greater than the change amplitude in autumn（5.13×10⁶cell/L， 1 237.74 ind./L， 382.48 ind./m²）； The average biomass of phytoplankton， zooplankton， and benthic animals at each survey site in spring were 5.48mg/L， 1.11 mg/L， and 461.31 g/m²， respectively， which were also higher than those in autumn（1.27 mg/L， 0.99 mg/L， 190.21 g/m²）. The Shannon-wiener diversity index（H′） and Pielou evenness index（J） results indicated that the aquatic biodiversity among different groups of Suzhou Industrial Park was at different levels from good to abundant， while the diversity was from good to excellent. Meanwhile the diversity index of phytoplankton and benthic animals in autumn has decreased significantly compared to spring. Overall， due to the distribution of submerged plants and temperature differences， aquatic organisms in the park exhibit certain spatiotemporal differences； Some water bodies have shown a certain degree of eutrophication， and further monitoring and early warning are needed.
