摘　　要：对 1998年 3月 6日至 6月 5日从广东省四会县大沙镇生物防治稻田和化学防治稻田采集到的 4 3种、 5 19只水生昆虫的分析研究。用Jaccard相似性指数、相异性指数、总体覆盖指数和发展相关指数四种生物多样性指数进行分析。结果显示 ,生物防治稻田和化学防治稻田在物种丰富度和总体丰富度上均有不同。分析显示 ,用总体覆盖指数和发展相关指数评价稻田水质更好。From March 6 to June 5, 1998, aquatic insects were sampled from a biologically controlled rice field (B\^F\^) and a chemical controlled rice field (C\^F\^) in Dasha town, Sihui County, Guangdong Province, P.R. China. Forty_three species of aquatic insects were collected. Four numerical methods, Jaccards coefficient of similarity, coefficient of difference, values of global covering and coefficient of development, were used to evaluate the pollution. The result showed that fauna in B\^F\^ is different from those of C\^F\^ in species richness and abundance. It is suggested that coefficient of development and global covering be more reasonable to assess the water quality of rice fields.
