摘要:
利用2008年云贵高原13个湖泊丰水期的全面水质调查数据,系统分析云贵高原湖泊水质现状,通过与历史资料对比,揭示20年来的水质变化,并分析水质变化的原因.同时利用主成分分析将23个水质参数概括为6个主要成分,除程海外所有湖泊水质均与第一主成分密切相关.人类活动影响下的水体富营养化、有机污染以及农业面源污染等是除程海外湖泊污染的主要驱动因子,程海水质变化主要受水体的矿化度增加所驱动.另外,根据各主成分得分,本文也对13个湖泊水质进行了综合评价,并在评价的基础上就湖泊的保护和治理提出建议.

Abstract:
In the present study, the water quality of 13 lakes, which are located in Yunnmi-Guizhou Plateau and total areas are more than 10km2, was evaluated according to the data from the investigation in 2008. TTie variation of trophic state was analyzed by comparing to historical data prior to 1988-1992. Furthermore, principle component analysis (PGA) was also used to evaluate the effect of water quality parameters, in which the comprehensive evaluation scores erf the 13 lakes were calculated according to extracted six principle components of the PCA. Changes in water quality of all lakes, except Lake Chenghai, was able to be explained by influences of trophic state, organic pollution and agricultural non-point source pollution under increasing anthropogenic pressure. However, water quality of Lake Chenghai was mainly affected by changes in water salinity. In addition, we also proposed the comments and suggestions about protection and management of these lakes.
