摘 要：
为探究不同强度森林抚育间伐对杉木人工林林分温湿度的影响,本文在坡度、坡向、土壤类型均相同的杉木人工林中设置固定标准样地,采取2种不同强度的抚育间伐,应用HOBO U23-00温湿度记录仪长期监测记录作业后林分温度、相对湿度动态,后续用SPSS等数据分析软件处理数据。结果表明:(1)不同抚育间伐强度对林内气温和相对湿度影响不同,强度抚育间伐后林内温度变化显著高于中度抚育间伐;强度抚育间伐后林内日温度变化表现为昼增夜降,月均温变化表现为高温季节升温、低温季节降温,林内相对湿度下降;而中度抚育间伐的影响则与之相反,表现出保温(温度稳定)增湿(湿度提高)效果。(2)成对样本t检验表明,与中度抚育间伐相比,强度抚育间伐对日均温、日平均相对湿度、月平均相对湿度的影响更为显著,对月均温的影响呈不显著。杉木人工林林内温度和相对湿度的动态变化表明,不同抚育间伐强度会对林内的大气温度和相对湿度产生不同的影响,相比于强度抚育间伐,中度抚育间伐后杉木人工林林内温湿度变化幅度小,林内小气候更为稳定,可在一定程度上减弱不良气候条件对杉木人工林经营的不利影响,为杉木提供更适宜的生长环境。

摘 要：
In order to explore the influence of forest tending and thinning with different intensities on the temperature and humidity of Chinese fir plantation, a fixed standard sample plot was set in the Chinese fir plantation with the same slope, aspect and soil type. Two kinds of tending and thinning with different intensities were adopted, and the dynamics of stand temperature and relative humidity after operation were monitored and recorded by HOBO U23-001 temperature and humidity recorder for a long time, subsequently, SPSS and other data analysis software were used to process the data. The results showed that:(1) Different tending and thinning intensities had different effects on the temperature and relative humidity in the forest. The temperature change in the forest after the intensive tending and thinning was significantly higher than that of the moderate tending and thinning. After intensive tending and thinning, the daily temperature in the forest increased in the day and decreased at night. The change in average temperature was manifested as the increase in high-temperature seasons, the decrease in low-temperature seasons, and the relative humidity decreased in the forest. While the effect of moderate tending and thinning was opposite, showing the effect of heat preservation(temperature stability) and humidification(humidity increase).(2) The t-test of paired samples showed that compared with moderate tending and thinning, the impact of intensive tending and thinning on daily average temperature, daily average relative humidity, and monthly average relative humidity was more significant, while the impact on monthly average temperature was not significant. The dynamic changes of temperature and relative humidity in Chinese fir plantations indicated that different tending and thinning intensities would have different effects on the atmospheric temperature and relative humidity in the forest. Compared with the intensive tending and thinning,after moderate tending and thinning,the temperature and humidity in Chinese fir plantations had a small change,and the microclimate in the forest was more stable. It can reduce the adverse impact of adverse weather conditions on the management of Chinese fir plantation to a certain extent,and provide a more suitable growth environment for fir.
