研究发现滇西北高山峡谷区云南松也具有通过林冠截流减少有效雨量和降低雨滴对地表的滴溅能量，减少降雨对土壤的侵蚀程度。产生较大直径的叶滴并引起林冠滴溅效应。云南松林冠在整个雨季截留率平均达３６ ．２９ ％ ，使林下有效降雨量仅为降雨量的６３ ．７１ ％ 。松林在整个雨季的林下溅蚀累积总量为４ ．９４ ｋｇ／ｍ ２ ，裸地为６ ．１２ ｋｇ／ｍ２ ，表明松林减少了１９ ．２８ ％ 的溅蚀全量。但林地在雨季中后期的各阶段溅蚀全量却高于裸地，特别在后期高出裸地２ ．６ 倍
The study found that Pinus yunnanensis in the mountainous valley of northwestern Yunnan also has the effect of reducing the effective rainfall and reducing the splashing energy of raindrops on the ground through intercepting canals and reducing the degree of soil erosion. Produce larger diameter leaf droplets and cause canopy splash effect. Pinus yunnanensis forest in the rainy season average retention rate of 36. 29% so that the effective rainfall under the forest is only 63% of the rainfall. 71%. Pine forest in the rainy season forest erosion cumulative total of 4. 94 kg / m 2, bare 6. 12 kg / m2, indicating a reduction of 19 pinewoods. 28% of the total amount of splashing. However, the total volume of forestland erosion in all stages of the mid to late rainy season was higher than that of the bare land, especially in late stage 2. 6 times
