摘要
随着经济社会的发展和人口的持续增长,水资源短缺已成为许多地区可持续发展进程中的首要问题。因受海岛地形限制,加之人类活动影响,玉环县可利用水资源量极缺,水体污染严重,是典型的资源型与水质型缺水地区。本文通过建立水资源可持续利用评价体系,评价其水资源与社会经济发展、生态环境间的协调发展情况,评价结果表明,可利用水量短缺、水环境污染严重、用水效率低是该地区水资源可持续发展的主要限制因素,并由此制定三种优化情景,分别在水资源可利用量、水环境、用水效率方面进行优化,计算结果表明,与开源相比,高节水与强治污能更为高效提升水资源的可持续性。
With the development of economy and society and the continued growth of the population,water crisis has become the primary issue in the sustainable development of many regions. The available water resources for Yuhuan county is extremely short and seriously polluted due to the island terrain restriction and the influence of human activities,which makes Yuhuan a typical resources-induced and quality-induced water shortage region. By building the index system of sustainable utilization of water resources,it evaluates the coordinated development of water resources,society,economy and ecological environment,which shows that the main constraints in the sustainable development of water resources in Yuhuan are water shortage,water contamination and low-efficiency water use. Three optimization scenarios are formulated based on the problems to increase available water resources,improve water environment,and raise use efficiency. The result indicates that compared with water excavation,high strength water saving and vigorous pollution control can promote the water sustainability more efficiently.
