摘要
以典型的亚热带湿润丘岗区——衡阳盆地为例,综合分析了其地表水资源脆弱性产生的原因及其表现。发现影响衡阳盆地地表水资源脆弱性的主要因素体现在气候、地形地貌、土壤和植被、人为活动以及经济发展因素5个方面。为了定量地评价地表水资源脆弱性,构建了一个包含9个反映地表水资源脆弱性内涵的评价指标体系,并且运用数学方法计算了各评价单元地表水资源的脆弱度。最后,针对评价结果提出了衡阳盆地地表水资源管理的措施。
Taking Hengyang basin, a typical hillock area in the subtropical region as a case, the reasons and forms of vulnerability in surface water resource were analyzed in this paper. It is found that the major factors influencing the vulnerability of surface water resource include the climate, topography, soil and vegetation, human activities and economic development. In order to quantitatively evaluate the vulnerability, an assessment indicator system, including 9 indicators, was sep up for the first time in the present study. Then, by using mathematical method to calculate the scores of vulnerability in each assessment unit, countermeasures for water resource management in Hengyang basin were proposed.
