| 摘 要： | 2008-2010年对滇西北洱海、程海、泸沽湖和碧塔海的软体动物现状进行了全面系统的调查,并在此基础上对比讨论4个湖泊间软体动物生物多样性的差异和水体富营养化过程中软体动物种群结构的改变.在泸沽湖采集到的软体动物标本种类最多,共计23种、1亚种；其次为洱海采集到14种,碧塔海和程海分别采集到6种和5种.将洱海记录的软体动物种类与此次采集到的种类对比,洱海的软体动物种群结构由底栖型向漂浮型转变,这可能与水体富营养化有关. |

| Abstract: | From 2008 to 2010, an intensive sampling was carried out, 77 sample sites (including 23 stations in Lake Er-hai, Lake Chenghai and Lake Lugu, respectively and 8 sites in Lake Bita) were sampled using handnet and dredge. Twenty-three molluscan species and one subspecies were collected in Lake Lugu, and 14 species were collected in Lake Er-hai. There were 6 and 5 species collected in Lake Bita and Lake Chenghai, respectively. Simpson diversity index and Shannon-Wiener diversity index were compared during four lakes. The substrate species decreased and floating species increased were performed in eutrophication. This study is the result of the first survey to the four plateau lakes, the difference of mollusks composition among these four plateau lakes were discussed. |
