We studied the diversity of phytoplankton of Jia Lize wetlands in Kunming and made the environmental evaluation of the wetlands on it. After sampling four ponds and three rivers, microscopic observation and identification analysis, we found that in the pond 1and 3, cyanobacteria algal blooms, high eutrophication, evaluating as the mid-polluted water type A, and in the pond 2 and 4, evaluating as the mid-polluted water type B, Chlorococcum algal blooms. Yang Lin river water was as the type B, Guo Ma river was type A, Mi Liang River water was micro-polluted. Studies showed that eutrophication of ponds were due to the chemical fertilizer, while Yang Lin River was polluted by the agricultural irrigation and living sewage nearby, highly polluted Guo Ma river was due to accommodate lots of industrial pollutant. It is necessary for local people to make the pollutant treatment and ecological protection of this area.
