为探索红壤侵蚀的有效控制措施，研究了中国东南部丘陵区不同植被系统（竹林、森林生态系统、柑橘果园和农田）对红壤侵蚀和养分的影响。结果表明，与裸地相比，不同植被系统均能显著减少土壤侵蚀和养分流失，其水土保持能力大小顺序为Ctr > BP > CF > FL > Br。植被还可以提高土壤肥力。土壤有机质、全氮和全磷含量在各植被系统中均明显高于裸地，尤其是表层土壤。植被系统显著改善了土壤物理性质。与裸地相比，各植被覆盖下土壤有机质、全磷、全钾和速效钾，尤其是土壤微生物量C、N和P均有所增加，但仍远低于预期值，因此这些生物测量仍需继续开展。
The effect of different vegetation systems including bamboo plantation (BP), forest ecosystem (CF),citrus orchard (Ctr) and farmland (FL) on erosion and nutrients of red soil were investigated in hilly region of southeastern China to find effective control measures for soil erosion. The results showed that all the vegetation systems could significantly reduce soil erosion and nutrient losses compared to bare land (Br).The ability of different vegetation systems to conserve soil and water was in the order of Ctr ＞ BP ＞ CF ＞ FL ＞ Br. Vegetation could also improve soil fertility. The soil organic matter, total N and total P contents were much higher in all the vegetation systems than in bare land, especially for the top soils. Vegetation systems improved soil physical properties remarkably. Compared to the bare land, soil organic matter, TP,TK and available K, especially soil microbial biomass C, N and P, increased under all the vegetation covers.However, they were still much lower than expected, thus these biological measurements are still needed to be carried out continuously.
