【摘要】 本文在对辽宁５８座水库调查的基础上，根据Ｆｕｚｙ聚类分析和逐步回归筛选的结果，采取了国内外实践证明效果较好和比较流行的评估鱼产力的模型，以现实连续五年的最高渔获量和浮游生物数据作为自变量，计算了其间的相关显著程度。认为形态土壤学指数（ＭＥＩ）效果最佳；形态流域指数（ＭＤＩ）在水库交换率大的地区使用时，应当增加径流深度与ＭＤＩ组成复回归分析。本文用形态土壤学指数和浮游生物两个变量，以吉林省高产的海龙水库对比，求出４３座水库可能达到的鱼产量。高产量达１００ｋｔ／ｋｍ２，低产者亦在１０ｔ／ｋｍ２以上。更多还原

【Abstract】 Basing on the investigation of 58 reserviors in Liaoning province and the result of in the sieving fuzzy cluster analysis and stepwise regression,we adopted the prevalent methods used at home and abroad to assess the model of fish productivity,with the maximum fish production of 5 serial years and the data of planktons as the independence.We elvaluated the relevant prominent results. Trought our study,the morpho-edaphic indes (MEI) is regarded as the best result,when the application of morpho-drainage basin indes (MDI) was used in high rate water-in and-out reservior,the complex regression analysis should be emphasized in runoff-depth and MDI.In this paper,prospective fish production fo 43 reserviors could be made out in comparison of the variations between MEI planktons and high fish production in Hailong Reservior in Jilin province.更多还原
