摘　　要：利用主成分分析和相关分析相结合的方法,建立水环境质量和经济发展的协调度模型,对千岛湖流域水环境与经济发展趋势及协调度变化趋势进行分析.结果表明,2000年以来千岛湖流域水环境质量与经济发展协调状况经历了从濒临失调向轻度失调再到趋近协调的转变过程:以5年为滑动周期考察协调度的演变趋势发现,2000-2012年千岛湖流域协调度大致呈"V"型趋势,2000-2004年水环境质量略有下降,经济发展缓慢,2004-2008年由于经济迅猛发展、水环境质量迅速下降,水质与经济发展处于失调状态,经过2008年转折点后,水环境质量开始改善,2008-2012年协调度达最高点,处于趋近协调,开始向初级协调状态转变.Based on the relationship study of water environment and economic development,this article established a coordination degree model about water environment quality and economic development combined with the concept of coordination degree.Through analysis of the variation trend of coordination degree between water environment and economic development （CDWEED） in Lake Qiandao basin,conclusions were obtained as follows.The CDWEED had undergone a transformation from inharmonious to elementary harmonious.Taking five years as a circle to study the variation of CDWEED in Lake Qiandao basin,the result indicated that the trend of CDWEED is almost in line with the ＂V-shaped＂ curve from 2000 to 2012.During 2000-2004,the water environment quality declined slightly and the economy developed slowly.During 2004-2008,the CDWEED was almost disharmonious,and water environment quality declined rapidly along with the rapid economic development.But the water environment quality began to improve after 2008,and the coordination degree reached the highest point between 2008 and 2012,and it was approaching the primary coordination.
