| 摘 要： | 运用径流小区法研究了闽北不同土地利用方式水土流失与降雨量的关系.结果表明：相同降雨类型下不同土地利用方式的水土流失量具有很大差异.裸露地（对照）小雨时也可能产生水土流失,而大雨以上降雨会产生严重水土流失;具有一定植被覆盖且采取水土保持措施的果园和锥栗林的径流量和泥沙量大幅度减少;而植被覆盖良好的杉木林即使大雨以上降雨也仅产生极轻微的水土流失.降雨量与径流量均呈极显著线性相关,降雨量越大,径流量越大;而降雨量与土壤流失量的相关性明显小于降雨量与径流量的相关性,影响土壤流失量的因素比径流量复杂. |

| Abstract: | The relationship between rainfall and losses of soil and water in diverse land-use types of Northern Fujian was investigated by establishment of runoff plot.The results indicated that on the premise of same rain type,significant differences in soil and water losses for various land were found.In the control,even light rain could bring soil and water losses.While for orchard and castanea henryi forest,runoff and sediment yield both reduced greatly.Regarding to Chinese fir with favorable vegetative coverage,m... |
