大连市水资源动态变化与评价研究

Study on dynamic changes and evaluation of water resources in Dalian

本文对大连市近10年的水资源状态进行了分析,结果表明大连市降水量和水资源总量总体上处于较低的水平,且具有较好的相关性。地表水是主要供水水源,非常规水资源将逐渐起到重要作用;农业用水逐渐减少,城镇、农村生活和工业用水逐渐增加。建议加强对长系列气候变化过程、雨洪资源利用技术方法、清洁生产、农田水利、节水技术、水资源优化分配理论与方法进行研究,提高水资源利用效率,保障大连市水资源可持续利用。

This paper analyzes the recent 10 year water resource conditions in Dalian. Resuhs show that both precipitation and total water resources fall in a lower level in Dalian as a whole, with a better correlation. The surface water is its main water supply source, and the unconventional water resources will more and more play an important role. Agricultural water will decrease but the urban and rural living and industrial water will increase gradually. It is recommended that the studies should be carried out on the long series climatic changing process, utilization techniques of rainfall flood resources, cleaner production, irrigation and water conservancy, water saving technology, and water resources optimal distribution theories and methods, so as to improve water use efficiency and guarantee sustainable utilization of water resources in Dalian.
