摘  要：
对遂昌县木荷生物防火林带和杉木的生长情况、林下植被、可燃物、土壤含水率等进行调查研究。结果表明:1 h和10 h时滞可燃物干重木荷林带内地表分别为377、591 g/m2,杉木林地为541、810 g/m2,木荷林内可燃物仅为针叶林的70%左右;不同坡位的木荷林生长和防火能力有一定差异,总体上呈现随海拔升高,生长和防火性能下降的趋势;木荷防火林带的土壤水分含量较杉木林高1.4倍左右,木荷防火林林土壤含水率总体上也呈现随海拔升高而下降的趋势。

摘  要：
Investigations were conducted on growth, understory vegetation, fuel load and soil moisture content under fire belt of Schima superba and Cunninghamia lanceolata plantation. The result demonstrated that mean dried weight of 1-hour and 10-hours timelag fuel in fire belt was 377g/m2 and 591g/m2, while that in C. lanceolata plantation was 541 g/m2 and 810 g/m2, indicating better fire-resistance of fire belt. The result also showed that the growth and fire prevention of fire belt decreased gradually with the increase of altitude. The mean soil water content of fire belt was around 1.4 time of that of C. lanceolata plantation. Soil water content of fire belt decreased with the increase of altitude.
