白鱀豚的发声及其与环境适应的初步研究

A PRELIMINARY STUDY ON THE RELATIONSHIP BETWEEN SOUND TRANSMISSION AND ENVIRONMENTAL ADAPTATION BY LIPOTES VEXILLIFER

摘要: 本文报道了人工饲养条件下白鱀豚的发声、发声信号的类型和信号参数及其与环境适应的关系.随着生活环境或其他条件的改变,白鱀豚发生信号的类型,发声的多寡等发生有规律的变化.可根据这些规律判别白鱀豚对环境的适应程度,所处的状态及性周期的发生等等.为白鱀豚的人工饲养及种群保护等提供科学依据.并为其声呐系统的研究打下良好的基础.

Abstract: The relationship between sound transmission, signal type, signal parameter and environmental adaptation of Lipotes vexillifer in captivity was preliminarily studied. In response to changes in the environment or other conditions, the signal type, signal transmission frequency, etc. change in a regular way. The degree of adaptation to the environment, sexual period status of Lipotes vexillifer can be judged according to the patterns of these changes. This information has provided a scientific basis for the rearing, conservation and research on the sonar system of Lipotes vexillifer.
