摘要:
采用定位研究方法和小集水区试验技术方法,通过两年的降雨量数据观测,对闽北地区木荷林地、杉木林地、封山育林地和对照等不同土地利用方式的小集水区进行坡面径流动态规律研究.研究结果表明:试验小区地表径流的产生主要是受降雨量的影响,而与降雨强度的关系不大,地表径流量与降雨量之间呈现出极显著的非线性二次抛物线关系(P<0.01).4种不同土地利用方式的月平均径流量一般随月降雨量的增大而增大,并且在同1月份间其平均地表径流量的大小趋势为:对照>封山育林>杉木>木荷,均是在6月份达到最大值,9月份出现最小值.对照比木荷林地、杉木林地、封山育林地更容易产生地表径流,林地具有较好的涵养水源和保持水土作用.
Abstract:
Dynamics of surface runoff in different land use,viz.forest lands of Schima superba and Chinese fir,enclosing and tending forest and the control in northern Fujian were studied for two years through in situ method of catchment.The results showed that the production of surface runoff was mainly related with the amount of precipitation,not with its intensity.Also significant parabola relationship between surface runoff and the amount of precipitation was found(P 0.01).Average monthly runoff in four land use patterns generally increased with the increase of monthly precipitation and the maximum runoff occurred in June and the minimum in September.In the same month,the order of the average surface runoff in different land use was the control enclosing and tending forest Chinese fir Schima superba.It is obvious that forests can play better role in soil and water conservation than other land use.
