摘要: 采用旷场试验,通过连续6 d的试验观察,结合林内生态保健因子,分析昆明种小白鼠经福建柏树林环境处理后其行为指标的变化,结果表明:1)处理组小鼠运动总路程大于对照组,表明经过树林环境处理可增强小鼠的兴奋性;2)中央格运动总路程,除第1天处理组小于对照组外,其余时间均是处理组大于对照组,表明经树林环境处理后小鼠兴奋性增强,认知能力提高;3)从中央格进入次数来看,第1、6天处理组稍小于对照组,其余4 d均是处理组大于对照组;此外,6 d试验中,处理组小白鼠进入中央格时间均高于对照组。说明小白鼠经过林内环境处理后焦虑状况得到改善,探究能力有所提高;4)6 d试验中,处理组小鼠体重一直高于对照组,粪便粒数一直少于对照组,说明经林内环境处理的小白鼠食欲旺盛,紧张感有所降低;5)通过典型轨迹可以看出,处理组小鼠在中央格区域涉足频率较高,总路程相对较大,说明经林内环境处理的小鼠运动量增大,精神状态得到改善;6)对比林内外保健因子:两者差距较大,福建柏林明显优于室内,适合人体保健功能的开发和利用。

Abstract: The effects of ecological health care factors on spontaneous behaviors of mice were studied through 6-day continuous observation in an open field. The results showed that: 1) The total movement distance of the experimental group was significantly longer than the control, indicating that the excitability of mice in Fokienia hodginsii forest was increased. 2) The traveling distance in the center for the experimental group was longer than that of the control except for the first day, indicating that the excitability and cognitive ability of mice after treated with the forest environment were improved. 3) With respect to the frequency of traveling in the center, the experimental group was lower than the control in the first day and the sixth day, but was higher in the other 4 days. In addition, the experimental group had longer residence time in the central grid than the control in the 6 consecutive days, suggesting that after treatment in the forest environment, the anxiety of the mice was positively remedied, and the exploring capability was enhanced to some extent. 4) In the 6-day experiment, the weight of experimental group was always higher than that of the control, but the waste grain number of the experimental group was less than the control, indicating that the appetite of the mice treated with the forest environment was improved dramatically, and the sense of tension was relatively decreased on the other hand. 5) From the typical trajectory, the frequency of the experimental group entering the central grid was higher than that of the control, and the total distance was longer, which indicated that the amount of mice exercise after treatment in the forest environment increased and the mental status was improved. 6) Comparing between indoor and outdoor health factors, we found a large gap between them, i.e. the Fokienia hodginsii forest was superior to indoor environment, and was suitable for development and exploration of human health functions.
