消费者亚系统对全球变化响应的研究

Responses of Consumer Subsystem to Global Changing

文章全面阐述了全球变化,主要包括全球变暖、紫外辐射增强以及由于人类活动而导致的土地利用的变化趋势,充分讨论了消费者亚系统对日趋剧烈的全球变化的响应模式。研究表明,全球变暖既可以通过影响动物的栖息地环境、食物分布格局等因素进而影响动物的种群特征及其分布,又可以在大型哺乳动物中造成性选择,还严重威胁到人类的身体健康。紫外辐射的增强导致许多皮肤病的发病率上升。土地利用的加剧,既可影响到动物的存活、空间利用以及空间社会组织,又能影响到物种多样性。总之,全球变化将对消费者亚系统造成众多不同程度的影响。

Global changing trend, including global warming, changing of ultraviolet radiation and land-use resulted from human activities was summarized, and the responses of consumer subsystem to accelerating global change. The results show that global warming affects animals＇ population characteristics and distribution, forms sexual select in big mammals, and threatens human healthy. Incidence of skin disease increases with the enhancement of ultraviolet. Pricking up of land-use influences animals＇ survival, spatial utilization, spatio-social organization and species diversity. In conclusion, global changes have different effects on consumer subsystem.
