为进一步查清厄瓜多尔境内地表水资源的时空分布特性,为其水资源综合利用提供基础数据,选择该国流量系列相对完整、质量较好、空间分布具有代表性且控制条件较好的水文站作为计算地表水资源量的主要依据站,绘制了地表径流量等值线图、计算了区域地表水资源量、分析了地表水资源量时空分布。研究结果表明:厄瓜多尔全国多年平均地表水资源量为3 617.47亿m~3,折合年径流深1 457 mm。全国9个DH中,多年平均径流量最大的为DH Napo,年径流量为1 321.54亿m~3,占全国的36.5%,径流量最小的为DH Manabi,年径流量为62.70亿m~3,仅占全国的1.7%。
In order to further understand the temporal and spatial distribution characteristics of surface water resources in Ecuador and provide the basic data for the comprehensive utilization of water resources in Ecuador, select the hydrological stations in the country that have relatively complete flow series, good quality, well-distributed spatial distribution and good control conditions The main basis for calculating the amount of surface water resources, draw the contour map of surface runoff, calculated the amount of surface water resources in the region, analyzed the spatial and temporal distribution of surface water resources. The results show that the average annual surface water resources of Ecuador for many years is 361.747 billion m 3, equivalent to an annual flow of 1 457 mm. Among the 9 DHs in the country, DH Napo, with the largest annual average runoff, has an annual runoff of 121.254 billion m 3, accounting for 36.5% of the national total. The smallest runoff is DH Manabi with an annual runoff of 6.27 billion m 3 , Only 1.7% of the country.
