摘要
毕节试验区是典型的岩溶山区,岩溶面积约占全区总面积的70%,其境内的六冲河流域面积占全区总面积38.1%;年径流量占全区总径流量39.5%。应用改进的SWAT分布式水文模型建立其降雨—径流模型,得到流域的水循环模式,进而推广到毕节市全域。根据数值模拟结果和调查资料计算表明,毕节市地表水资源供需矛盾突出;地下水资源虽然丰富,但利用率极低,工程性缺水明显。因此,必需对毕节市地下水资源作专项研究,合理开发,才能适应当地经济社会发展的客观要求。
Bijie experimental region of poverty improvement and ecological construction is the typical karst area, as the karst area accounts for 70%. Within boards Liuchong river basin area accounts for 38.1% of the whole area, and the annual runoff in the region accounts for 39.5% of the total. The improved SWAT model is built to simulate the rainfall and flow about Liuchong River in Bijie. According to the simulation, Water circle about Liuchong river is obtained, and then extended to Bijie further. From the results and survey data, Water supply and demand of Bijie is calculated, and it can be drawn that in Beijie surface water resources supply and demand contradictory is prominent, although rich in groundwater resources, the utilization rate is extremely tow, and engineering water shortage is significantly. Therefore, it is necessary to study the groundwater resources on special research and rational development, in order to meet the objective requirements for local economic and social development.
