%X 为实现北京市鹫峰国家森林公园多层土壤温度全年的稳定监测,搭建了土壤温度远程监测系统,将收集到的多层土壤温度数据归纳整理,探究多层土壤温度的季节性变化规律和日变化规律。结果表明,春夏两季深层土壤温度低于浅层土壤,1.2 m深处与近地表之间有3～10℃的负温差。鹫峰地区森林土壤上下层温度的转换时间在9月底至10月初。因此,森林深层土壤的温度将高于浅层土壤的温度,土壤上下层之间存在正温差,可以为温差发电提供必要的条件。冬季多层土壤的温度较为稳定,且1.2 m深处与近地表之间有7.1～9.5℃的温差,达到全年最大。使用Origin软件对采集到的数据进行回归分析,得出了每个季节多层土壤温度的垂直分布规律。研究结果可以为鹫峰森林土壤温差变化提供参考,并为森林土壤温差发电装置的研究提供理论依据。</br>With the rapid development of the technology for forestry information collection, the wireless sensor has been widely applied in precisely monitoring forest environment. However, the complex environment of forest region makes it difficult for the charging of wireless sensors. Thermoelectric power generation can overcome the charging problem. Since the forestry soil is huge reservation of thermal energy, the soil temperature varies according to different depths of the forestry soil. It is necessary to monitor the temperature variation in forest soil for a long period in order to analyze the changing patterns. In this study, the monitoring system of soil temperature was developed. The data of multi-layer soil temperature in Jiufeng natural forest for four seasons were collected. Based on the experimental data, the seasonal changing patterns of the multi-layer soil temperature were explored, so did the daily changing patterns. It was found that the temperature of deep soil was lower than that of shallow soil in spring and summer. The negative temperature changes between the 1.2 m deep layer and the soil surface were in the range of 3-10℃. The conversion time of the forest soil in Jiufeng natural forest is between the end of September and early October. Since then, the temperature of the deep soil would be higher than that of the shallow soil. There are positive temperature differences between the deep soil and the shallow soil, which can provide necessary conditions for thermoelectric power generation. In winter, the soil temperature is relatively steady. The temperature changes between the 1.2 m deep layer and the surface maintain were between 7 and 10℃, reaching the annual peak temperature. In addition, the regression analyses of the collected data were conducted by using the Origin software, accordingly obtaining the vertical distribution pattern of the multi-layer soil temperature in each season. The results of this study can provide reference for the changing patterns of soil temperature distribution in Jiufeng natural forest and the theoretical foundation for the thermoelectric power generator
