Study on the Flood Water Resources and its Utilization in Western Jilin

摘要

Water is the foundational natural resource and strategic economic resource, which plays an important role in maintaining ecosystem and environment. Considering that the flood water resources are a special form, the floodwater utilization is a special way of surface water resource utilization. Based on the hydrologic data from 1956 to 2010, this paper focuses on the study of flood water resources in the western of Jilin province, including analysis of the surface runoff, assessment of ecological basic flow, flood water resources availability and utilization potential of major rivers. The results show that the amount of flood water resources availability and utilization of Nen River, the second Songhua River and Taoer River is 45.73×10~8m~3/a, 22.38×10~8m~3/a and 4.09×10~8m~3/a in the period of 1956-2010, respectively. The total amount is richer than the annual mean surface runoff (5.39×10~8m~3), meaning that flood water reources have a high potential to use. Then, The main characteristics and factors of flood water resources are analyzed in the study area. In additon, this paper presents several approaches for floodwater utilization to provide support for sustainable utilization of water resources in Western Jilin in future.
