摘要

该文依据野外人工降雨试验结果，对2年生人工沙打旺、草木樨草地盖度季动态及其水土保持效益作了分析和探讨。结果表明，草地盖度季动态呈幂函数分布；盖度与产流开始时间、径流量、泥沙量之间均存在指数相关关系；人工沙打旺草地盖度峰值与黄土丘陵区多年降雨年内分布峰值出现的时间同步，加之盖度较大，具有良好的水土保持效益。

Abstract

Based on the experiment data of field simulative rainfall

the seasonal change of coverageof two years old artificial grassland of Astragulus adsurgens and Melilotus albus and their benefits ofsoil and water conservation were analysed and discussed in this paper.The results are showed as fol-low the seasonal change of coverage was power distribution;the correlation are exponent functionbetween coverage and the time of runoff beginning

or runoff amount

or sediment yield seperately

the peak value of coverage of artificial grassland appeared at the same time as the peak value of year-ly rainfall dstribution appeared.Meanwhile

bacause of high coverage

the benefit of soil and waterconservation was very good.
