水安全内涵及其评价研究<br /> ——以三峡库区万州为例<br />
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 7
Abstract
本文讨论水安全的内涵,提出内容、目标和时间水安全三维概念模型,认为在水安全目标与时段确定前提下对水安全三要素(水资源安全、水环境安全、水生态安全)的研究是水安全评价的主要内容,是确定安全水平的核心要素。本文构建水安全评价指标体系、确立评价方法与评价标准,对三峡库区万州进行现状评价,并采用常规发展与优化发展两情景模拟对比的方法对其未来的水安全趋势进行预测评价。评价结果显示:现状水安全处于一般状态;常规发展情景下水安全水平日趋下降,优化发展情景下水安全逐步趋于良好达到理想。治理水土流失、控制污染物的排放、提高社会经济用水效率将是万州区水安全保障的主要途径。 关键词:水安全;内涵;评价;万州
