滇油杉林下死可燃物含水率与温湿度关系模型研究

Relational Model among Dead Combustible Moisture Content,Temperature and Humidity under Keteleeria evelyniana Forest

[目的]研究滇油杉林下死可燃物含水率与温湿度关系模型。[方法]以滇油杉林下三类死可燃物为研究对象,借助于恒温恒湿箱对不同温湿度组合下的含水率进行测定,并研究三类死可燃物含水率与温度、湿度、温湿度的关系。[结果]在相同湿度条件下,死可燃物含水率随温度的升高而降低,但在不同的湿度下具有不同的变化规律;在相同温度条件下,死可燃物含水率随相对湿度的增大而增大,但在不同的温度下具有不同的变化规律;温湿度共同作用影响死可燃物的含水率,且不同的死可燃物有不同变化规律。[结论]可燃物含水率是受多种因素影响。滇油杉林下三类死可燃物含水率从小到大依次为粗大死可燃物、腐殖质、细小死可燃物。

[ Objective ] Relational model among dead combustible moisture conteut,temperature and humidity under Keteleeria evelyniana fnrest was studied. [ Method ] This paper took three kinds of Keteleeria evelyniana fnrest dead combustible as the research objects, with the help of constant temperature constant wet box to measure the moisture content in different combinations of temperature and humidity, and studied the relationship among moisture contents of three kinds of dead combustible, temperature and humidity. [ Result ] The resnhs shnwed thai the moisture content of dead combustible decreased with the increase＇ of temperature under the same humidity condition, but has different change law under different humidity. In the same temperature, the moisture content increased with the increase of relative humidity, but has different change law untter different humidity, the interaction of temperature and humidity could affect the moisture eonteut of dead combustihle, and different kinds of combustible have different rules. [ Conclusion] Moisture content of dead combustible is influenced by many factors. Three kinds of dead eombustible moisture content from small to large order is： thick dead combustihle,humus,small dead cnmhustible.
