水位变化影响湖泊水质、水量和生态系统功能，是研究湖泊演变的重要内容，但目前针对滇中高原湖群水位变化特征还少见系统报道.本文选择滇池、抚仙湖、阳宗海3个滇中高原湖泊作为研究对象，基于1988-2015年实测水位数据和Mann-Kendall趋势检验法评估了3个湖泊水位变化特征；运用RClimDex模型获得了流域极端降水指标，结合其他指标构建了基于极端气象因子的湖泊水位驱动力指标体系；采用主成分-多元回归模型，解析了极端降水、蒸发等气象因子对滇中高原湖泊水位变化的贡献.结果表明：①滇池、抚仙湖、阳宗海水位年际波动不突出.滇池的年平均水位总体略呈上升趋势，年均上升0.025 m.阳宗海和抚仙湖水位无明显变化.②滇中高原湖泊流域的极端降水指数年际变化趋势不明显.滇池的蒸发量呈明显减小趋势，年均减小21.05 mm.抚仙湖蒸发量呈明显增加趋势，平均每年增加5.52 mm.阳宗海蒸发量的变化不明显.③气象指标可解释滇池水位变化的49.7%，滇池水位变化受气候变化和人类活动的综合影响；阳宗海和抚仙湖水位变化主要受气象条件控制，蒸发量、综合降水指标和连续降水指标对阳宗海水位变化的解释率高达93.3%；综合降水指标和干旱状况指标可以解释抚仙湖水位变化的64.5%.极端降水指标对解释高原湖泊水位变化具有重要作用.

Zizania latifolia mainly grows in the land/inland water ecotones of river channels and lowland swamps of Lake Taihu Basin.Its growth condition is representative in this area.Four different environment conditions such as implanted ecological filter bed,biological oxidation pond,subsurface flow and surface flow integrated artificial wetland and horizontal subsurface flow artificial wetland have been designed based on the status of land/inland water ecotones of river channels.The growth adaptabilities of Z.latifolia in different environments were studied so as to provide a scientific evidence and technical support for establishment and restoration of the degraded vegetation communities of land/inland water ecotones of river channels.The results showed that Z.latifolia was able to adapt to different growth environments such as zeolite matrix and hydroponics;the growth rate and luxuriance degree differed among substrates.
