摘要
对永春碧卿国有林场山地防火林带的调查研究表明：山地防火林带土壤肥力可分为３个等级，林木生长与土壤肥力等级呈正相关。土壤容重、土壤水分、土壤有机质、全氮、速效钾等几个指标可以综合反映山地防火林带（路）的土壤肥力水平。米老排防火林带具有明显的经济效益和生态效益。
The investigation on fire prevention forest belts in the mountain area of Biqing National Forest Farm of Yongchun indicates that the soil fertility of fire prevention forest belts in the mountain area may be divided into three grades and the forest tree growth and the soil fertility grade assume the positive correlation.Several indexes of soil volume weight,soil water,soil organic matter,total N and rapidly available K may comprehensively reflect the soil fertility level of fire prevention forest belts(roads).Mytilaria laosensis fire prevention forest belts possess the evident economic benefit and ecological benefit.
