摘要

在野外小区径流实验基础上，通过经转换的曼宁公式，对不同坡地地表的糙率系数n值进行了定量研究。结果表明：林地上的糙率系数n值与林地地表残存的枯落物量和生长的草量呈正相关关系，不同土地利用现状的地表糙率系数n值按由低到高的顺序排列，依次为土质路面、农耕地、核桃果园、人工刺槐林地、灌木林地和人工油松林地。该文还探讨了糙率系数n值与地表水分渗透量的关系，初步结果表明：糙率系数n值较大的地表其水分渗透能力也较大。

Abstract

Based on the field surface shallow flow experiments

the roughness coefficient value (n)on different land have been quantitatively demonstrated by changed Manning Formula in this pa-per.The result shows that the relationship of roughness coefficeint value(n)to litter and grassamount appears to be an orthographic correlation on forest land.And the order of roughness coeffi-cient value (n) from lower to higher on different condition of land use is as follows:soil road

cultur-ing land

walnut plantation

the land of artificial locust forest

the land of shrub forestry and theland of artificial Chinese pine forest.This paper deals also with the relationship between roughnesscoefficent value(n)and the infiltration of water.the preliminary result shows that the higher theroughness coefficient value (n) is

the more the infiltration of water will be.
