1、程海水环境质量现状及趋势分析摘要:程海是云南省九人高原湖泊之一,也是全世界三个天然生长螺旋藻的湖泊Z-O近年来,随着程海流域经济社会的发展,给程海的水环境质量带来了负面影响,水体透明度下降,湖面时常发生水华现象,土著鱼种迅速消亡等,都是程海水质下降,湖泊功能衰退的征兆。本文应用对程海近十年来的水质监测资料,科学、客观、全面地分析了程海的水质现状及运动变化趋势,为程海的健康状况出据检测报告,为湖泊的健康起到耳目作用。关键词:程海,水质现状,变化趋势,污染源Abstract:chenghaiisyunnannineplateaulakes,且ndalsoone

7、码:A文章编号:引言:云南省水环境监测中心丽江分中心对程海的水质监测已有三十多年,在这三十多年里,我国的社会经济发生了翻天覆地的变化,程海流域的社会经济也发生了巨大的变化。程海流域的社会经济发展了,人民的生活富裕了,但是流域内社会经济的发展给程海的生态环境带来了前所未有的沉重负担。湖泊功能自然的形成、退化到衰老是一个非常缓慢的过程,需要上万年,甚至几百万年的时间,人类的感观难以觉察到其口然变化的过程,只有在人为排放含工业废水和生活污水的条件下才会在短时间内出现水质变化,促使其功能快速退化、衰老。在这短暂的三十年里,特别是在近十年,程海的水质变化、功能衰退呈
