摘要
利用长汀、安溪、南安等地的试验资料，就坡度和坡长对土壤侵蚀的影响进行了分析．指出在２０～３０°的坡地区间，土壤侵蚀最严重，是山地生态脆弱地带，并从理论上论证了坡地侵蚀的坡度极限为２７．６°。建议在较陡坡上用草带间作和山边沟替代梯田。
Based on the data obtained from the Changting,Anxi and Nanan experimental stations, the analyses have been made on the relationship between the inclination and length of slope and soil erosion. The results show that the susceptibility of soil erosion to inclination and length of slope is higher on the tillage slope than that on the natural slope. The slope from 20°to 30°was defined as a weak ecological belt, and the maximum precipitation erosion slope has been proved to be 27. 6°in theory calculation.It was found that the belts of Vetiveria have good function of soil and water conservation,and it is suggested that belts of Vetiveria combined with hill side ditch go instead of terrace on steep slope.
