This project was carried out to clarify the causal relationships among the quality of aquascape, ability of water purification and biodiversity in aquatic environment. In result, the role of reed bed of Lake Shinji for the maintenance of higher diversity of benthic animals was found by comparing the diversity indexes between inside and outside of the reed bed. However, some exceptions were also investigated, and thus the indirect effect of reed bed which influenced the composition of bottom sediment was suggested. Concerning the diversity of aquatic macrophytes, turnover rate differed among species growing in the 45 irrigation ponds. No relation was found between species richness and pond area. Turnover rate per pond was 35.8% on average, while that of total ponds investigated (i.e.metapopulation) was 8.1%. Plants growing in salt marsh and brackish water were also investigated around Lakes Shinji and Nakaumi and each 4 species were found. Though the miscellaneous facts were found by the present study, main purpose could not be attained because of a limited time. Further study should be done in the future.

本项目旨在阐明水景质量、水净化能力与水环境生物多样性之间的因果关系。结果表明，通过对芦苇床内外多样性指数的比较，发现了真鸡湖芦苇床对维持较高底栖动物多样性的作用。然而，也对一些例外情况进行了调查，从而提出了芦苇床对底部沉积物组成的间接影响。在水生植物多样性方面，45个灌池中生长的水生植物的周转率存在差异。物种丰富度与池塘面积无明显关系。平均每个塘的周转率为35.8%，而总调查塘（即元种群）的周转率为8.1%。此外，还调查了真次湖和中川湖周围盐沼和微咸水中的植物，各有4种。本研究虽然发现了杂项事实，但由于时间有限，未能达到主要目的。今后还需进一步研究。
