摘要
一生态位的研究是理论生态学的一个重要领域。Grinell(1917)将生态位定义为物种在环境中的最后分布单位,强调生态位的空间概念(space niche);Elton(1927)特别强调物种与其他种的营养关系(trophic relationship)。
The concept of ecological niche in natural ecosystem is re-interpreted in man-made ecosystem,and the niche theory is applied to the paddy field ecosystem.The nichs efficiency is significantly improved by intrducing new ecological units and directively regulating the factor space of economy-ecology for the int(?)grated utilization of paddy field.
