(1)分析尼罗河径流量的季节变化特点及原因。
(2)为什么尼罗河枯水期径流主要来自白尼罗河?
(3)简述尼罗河径流季节变化对其下游河谷及三角洲古代农业生产的影响。
答案 (1)季节变化特点:洪水期出现在北半球夏半年,枯水期出现在冬半年。
原因:尼罗河三个源流的流域大部分,以及流域降水量最丰富、产流量醉倒的地区,位于北半球热带草原带(热带草原气候区),雨季出现在北半球夏半年,产生径流多;干季出现在冬半年,产生径流少。
(2)(尼罗河枯水期时,青尼罗河和阿特巴拉河都进入枯水期,产生的径流量少:)白尼罗河源流位于南半球,南半球为雨季,所以白尼罗河产生的径流最多。
(3)尼罗河径流季节变化显著,导致其下游河谷及三角洲农业生产具有明显的季节变化。洪水每年定期泛滥,洪水泛滥之后,开始农耕。枯水季节是作物生长及收获季节。洪水泛滥时在被淹农田表面沉积一层肥沃的淤泥,使土壤年年肥力不减,有利于农作物的生长。
