地表径流量指的是降水或融雪强度一旦超过下渗强度,超过的水量可能暂时留于地表,当地表贮留量达到一定限度时,即向低处流动,成为地表水而汇入溪流的水量。
化学溶蚀速率与地表径流量呈正相关关系。
Chemical erosion rate has a positive correlation with runoff.
开发建设项目建成后往往使地表大面积硬化,从而改变项目区入渗、蒸发、地表径流量和特性。
Usually the surface would be hardened in a large area after completion of development and construction projects.
而地表径流量、次地表径流量、地下径流量及河川径流量主要受降水量变化的影响,受气温变化的影响相对较小。
But the surface runoff, subsurface runoff, ground water and runoff are mostly effected by precipitation. The temperature influence on them is comparative less.
