地震前动物习性异常原因研究

本文介绍了有关SO_2气体对小白鼠、蚯蚓、虎皮鹦鹅的行为影响的实验。实验表明,小白鼠和蚯蚓在浓度为50ppm的SO_2气体的作用下出现了行为反应,在浓度为100ppm和150ppm的SO_2气体的作用下活动频繁,出现逃避现象。虎皮鹏鹉在浓度为100ppm的SO_2气体的作用下叫声频度出现较为明显的异常,在浓度为400ppm的SO_2气体的作用下叫声频度显著下降,并出现呆痴、(?)毛、甩头等异常行为。因此地震前所溢出的含硫地气可能是引起鼠类、蚯蚓和虎皮鹦鹅等动物震前行为异常的主要因素之一。

A STUDY ON THE CAUSE OF ABNORMAL ANIMAL BEHAVIOR BEFORE EARTHQUAKES--THE EFFECTS OF SULPHUREOUS GROUND GASES

In this paper, the effects of SO₂ gas which is a main composition in earthquake premonitory sulphureous ground gases on the behavior in mice, earthworm and budgeriga (Melopsittacus undulafus L.)are discussed.The experiments show that in mouse and earthworms some behavior responses are exhibited under the action of SO₂ gas at 50 ppm, and at 100 ppm, they present behavior responses, such as frequent actings and escapings and so on. In budgerigas, the calling frequencies present relatively obvious abnormalities under the action of SO₂ gas at 100 ppm, and at 400 ppm, the calling frequencies remarkably decrease and the behavior responses, such as dull-looking, spreading plume and swinging head and so on are presented. Spilling sulphureous groundgases prior to earthquakes may be a main factor exciting behavior responses in rats living in holes, earthworm living in underground and budgeriga with sensitive olfaction.
