以宁化紫色土侵蚀区油茶林为研究对象,比较分析油茶幼林不同水土保持措施对土壤侵蚀的影响。结果表明:水保措施的施用限制了油茶幼林的生长;水保措施的施用明显提高了地表植被覆盖度;水保措施的施用明显减少了径流量和泥沙量,其中C2模式(鱼鳞坑种植油茶+种植圆叶决明)的效果更为明显;水保措施的施用对土壤养分的影响存在差异,其中C1模式(草带+鱼鳞坑种植油茶+种植圆叶决明)促进养分的累积,而 C2模式则降低土壤养分含量。总的来说,C1模式是一个值得在紫色土强度侵蚀区推广的水土保持措施。
以寧化紫色土侵蝕區油茶林為研究對象,比較分析油茶幼林不同水土保持措施對土壤侵蝕的影響。結果錶明:水保措施的施用限製瞭油茶幼林的生長;水保措施的施用明顯提高瞭地錶植被覆蓋度;水保措施的施用明顯減少瞭徑流量和泥沙量,其中C2模式(魚鱗坑種植油茶+種植圓葉決明)的效果更為明顯;水保措施的施用對土壤養分的影響存在差異,其中C1模式(草帶+魚鱗坑種植油茶+種植圓葉決明)促進養分的纍積,而 C2模式則降低土壤養分含量。總的來說,C1模式是一箇值得在紫色土彊度侵蝕區推廣的水土保持措施。

Taking Camellia oleifera plantation in purple soil erosion as research obj ects,the effects of different soil and water conservation measures for young plantation of Camellia oleifera on soil erosion were compared.Result shows that applying measures for soil and water conservation restricts growth of young plantation of Camelliaoleif-era,increases obviously the vegetation coverage and decreases runoff & sediment,in which C2 mode(planting Ca-melliaoleifera in Fish-Scale pits+planting Cassiarotundifolia)have more obvious effect.Applying measures for soil and water conservation have different effects on soil nutrient content.C1 mode (grass strips+planting Cassia rotundifolia)stimulate nutrient accumulation and C2 mode decrease soil nutrient content.In general,C1 mode is worth to be promoted in strong erosion land for purple soil.
