厄瓜多尔水资源时空分布及变化规律

Spatial and Temporal Distribution and Variation of Water Resources in Ecuador

摘要: 根据厄瓜多尔水资源综合规划中水资源调查评价成果(1971~2010年系列)，研究了厄瓜多尔水资源时空分布特征及变化规律。厄瓜多尔水资源量丰富，但时空分布不均匀，东部地区和安第斯山脉两侧山坡径流较大，西部沿海及安第斯山脉内部的高原盆地径流相对较小；中部和西部地区水资源年际和年内变化大，东部地区水资源年际和年内变化小，水资源出现连丰或连枯情况。

Abstract: Based on the results of the investigation and evaluation of water resources in Ecuador water resources comprehensive planning (1971~2010 series), the temporal and spatial distribution and variation of water resources in Ecuador were studied. Water resources of the Ecuador are relatively abundant, but the spatial and temporal distribution is uneven; runoff of the eastern region and the Andes mountains on both sides is large; runoff of the west coast and the interior of the Andes plateau basin is relatively small; the interannual variation and concentration degree during the year of water resources in the central and western regions are larger than those in the east; water resources appear continuous water year or continuous dry years.
