过去三十年来，由于热带雨林转变为橡胶种植园，西双版纳（中国西南部）的景观发生了巨大变化。本研究描述了热带雨林转变为橡胶林对潜在飞溅侵蚀率和实际飞溅侵蚀率的影响。橡胶园的平均潜在飞溅侵蚀率比开阔地高2.1倍，而雨林仅比开阔地高1.2倍，表明橡胶园树冠极大地加剧了雨水飞溅侵蚀。橡胶园的平均实际飞溅侵蚀率是雨林的2.0倍，表明雨林对飞溅侵蚀的控制更为有效。橡胶园梯田的实际飞溅侵蚀率明显低于立管岸，表明立管岸对雨滴飞溅更为敏感。因此，在这个梯田橡胶种植园中，用生产性植被或枯枝落叶/覆盖层保护梯田立管至关重要。这些结果清楚地表明，将热带雨林转变为橡胶种植园对控制飞溅侵蚀具有负面影响。
The Xishuangbanna (SW China) landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations. This study characterized the influence of conversion of tropical rainforest to rubber plantation on potential splash erosion rate and actual splash erosion rate. The average potential splash erosion rate was 2.1 times higher in the rubber plantation than in the open, while for the rainforest it was only 1.2 times higher than in the open, suggesting that the rubber plantation canopy greatly increased the rainsplash erosion. The average actual splash erosion rate was 2.0 times higher in the rubber plantation than in the rainforest, demonstrating that the rainforest was more effective in controlling splash erosion. The actual splash erosion rate was considerably lower in the terrace bench than in the riser bank in the rubber plantation, indicating that the riser bank was more sensitive to raindrop splash. Hence, protection of terrace risers with productive vegetation or litter/mulch layer is of vital importance in this bench-terraced rubber plantation. These results clearly show that conversion of tropical rainforest to rubber plantation had a negative effect on controlling splash erosion.
