摘要/Abstract

摘要： 冗余理论是20世纪90年代发展起来的一个生态学理论.本文扼要介绍了冗余的概念、冗余假说和冗余度的含义,对近年来国内外物种冗余、层次冗余、基因冗余和生长冗余等有关冗余理论和方法的研究进展作了简要回顾和分析.在此基础上,提出了农作物最佳生长冗余度假说:在一定的栽培管理条件下,农作物存在着一个与最高产量相对应的生长冗余度(最佳生长冗余度),在生产中,如果能通过各种栽培管理措施使农作物的生长冗余度达到最佳值,就能获得高产.用水稻高产栽培实例,对这一假说作了分析和验证.

关键词: 冗余, 冗余度, 最佳生长冗余度, 农业生态系统管理

Abstract: Redundancy theory is an ecological theory developed in 1990s.This paper gave a brief introduction on the concept of redundancy,its hypothesis and redundancy degree,and briefly reviewed the research advances in redundancy theory and in the methodologies about species redundancy,layer redundancy,gene redundancy,and growth redundancy.A hypothesis of optimal growth redundancy degree (OGRD) was proposed,i.e.,under certain cultivation and management conditions,there existed a growth redundancy degree corresponding to the highest crop yield,and a high yield would be obtained if OGRD could be achieved through the regulation of management practices.The hypothesis was tested by using the data from high-yielding rice cultivation cases.

Key words: Redundancy, Redundancy degree, Optimal growth redundancy degree, Agro-ecosystems management
