海南国际旅游岛旅游水环境现状调查与分析

界定了旅游水环境的概念,采用资料调查、咨询访问和个别现场调查等方法,对海南省旅游水环境进行了调查与分析。结果表明,海南省1989年至2008年旅游业的用水量占全省生活用水量的比例都很小,对海南水资源总量的影响也很小,2008年三亚市、海口市和万宁市三个城市的旅游业用水量之和占到全省旅游业总用水量的79.9%;海南省河流、水库、海域和地下水环境质量总体优良,仅有少量监测出现超标现象;在旅游水环境重点保护对象中,海南中部山区河流源头水、主要滨海旅游区近岸海域、三大河流和两大水库等水体水质均为优良,城镇、乡镇集中式生活饮用水水源地和城市河段大多数水体水质满足环境功能要求,有少量水体水质超标。河流、水库和个别城镇集中式生活饮用水水源地水质超标主要是农业面源污染和生活污水的污染。乡镇集中式生活饮用水水源地水质超标的主要原因是受海水、生活污水、生活垃圾、分散式畜禽养殖污水等的渗透污染和土壤中铁、猛背景值含量较高所致。
