摘要
水源地脆弱性评价是高原盆地城市水源地科学保护和生态恢复措施制定的基础。以高原盆地城市水源地脆弱性评价指标体系为基础,运用物元方法和可拓理论构建了高原盆地城市水源地脆弱性物元可拓模型,并实例对云南省9个高原盆地城市水源地脆弱性进行了评价。评价结果表明:信房、北庙两水源地处于轻度脆弱性状态;云龙、松华坝、潇湘、九龙甸、东风等水源地处于中度脆弱性状态;菲白、渔洞等水源地处于高度脆弱性状态。9个水源地对不同评价指标的脆弱程度也各不相同。评价结果与水源地实际情况相符。
Vulnerability assessment of water sources is the basis of scientific protection and ecological restoration for plateau basin urban water resources. Based on the vulnerability assessment index system of urban water sources in plateau basin, using the matter-element method and extenics ,the Matter-Element and Extension Sets is built and applied to nine examples. The assessment results show that the situation in Xinfang and Beimiao water sources area are mild vulnerable; the situation in Yunlong, Songhuaba, Xiaoxiang, Jiulongdian and Dongfeng water sources area is middle vulnerable; the situation in Feibai,Yudong water sources is high vulnerable. The vulnerability degree of nine different water sources to different assessment indexes is different. The results coincide with the actual situation.
