摘要
山地立体农业是一种"以山为梯,立体开发"的充分利用空间、时间和地形的差异进行多层次配置,实现多物种稳定共存、多质能循环转换的科学农业。本文以生态学的观点全方位解析山地立体农业,用生态位理论对其进行解释,以云南的山地立体农业为例进行分析,提出山地立体农业的生态单元,并用Lotka—Volterra模型解释山地立体农业物种稳定共存的生态学因由,从而在认识上对山地立体农业达到一个新的高度。
The mountainous three-dimensional agriculture makes full use of space,time and the difference of terrain for multi- level configuration to realize the multiple species coexistence and material and energy transformation in cycles which uses the mountain as a ladder and develops it dimensionally. This paper uses the ecological view to comprehensively analyze the mountainous three-dimensional agriculture and applies the theory of ecological niche to explain it with Yunnan's mountainous three-dimensional agriculture as an example for analysis. The ecological units of the mountainous three-dimensional agriculture are put forward and the Lotka—Volterra model is used to make clear the reason of the stable coexistence of species of mountainous three-dimensional agriculture so as to get a new understanding of the mountainous three-dimensional agriculture.
