An ecological niche theory approach to the measurement of brand competition
      
The data are consistent with the fine-grained niche theory but difficult to reconcile with bottlenecks and genetic drift.
      
In this paper GF variation is viewed along structural niche axes, and related to classical niche theory; several corollaries of the theory are examined in the light of plant GF patterns.
      
When applying niche theory to plants, the mechanisms of competition are ill-defined and the assumption of bell-shaped response curves for species unrealistic.

The niche theory is one of the most important basic theories about ecology.it has been attached great importance to in foreign ecological circles while in our country the study of niche has just been made. In order to bring about a thorough study of this theory the significance of applying the niche theory to ecologieal agriculture is dealt with in this paper with a living example of application of it to guide and organize the agricultural production.

生态位理论是生态学最重要的基础理论之一。国外生态学界对这一理论非常重视,我国对生态位的研究则刚刚起步。为了促进这一理论的深入研究,本文通过生态位原理在指导和组织农业生产中的实例,论述生态位原理在生态农业中应用的重要意

The niche breadth,the niche overlap and the percentage similarity of three species of main egg-parasites of rice planthoppers(Anagrus nilaparvatae Pang,Anagrus longitubulosus Pang and Anagrus paranilaparvatae Pang)were estimated by means of investigating their resource niche in paddy fields.After that,the conservation of Anagrus spp.in the natural control of rice planthoppers were discussed according to the niche theory.

本文通过稻飞虱卵寄生蜂——缨小蜂资源生态位的田间调查,测定3种主要缨小蜂(稻虱缨小蜂Anagrus nilaparvatae 、长管稻虱缨小蜂 Anagrus longitubulosis、拟稻虱缨小蜂 Anagrus paranilaparvatae)的生态位宽度,生态位重叠和生态位相似性比例.在生态位测定的基础上,按生态位的理论观点,讨论了稻飞虱缨小蜂保护问题。

The plant niche fitness theory and its simulationi method in this paper are nwe developments of the niche theory and its quantitative analysis method. Taking plants in sandy areas as objects for research, we constructed a theoreitical niche fitness pattern and its computational formulae as well as the simulation method of water fitness process. On the basis of expermiental results, we have done computational analyses and numerical simulation concerned. The simulation result has a very high accuracy,...

The plant niche fitness theory and its simulationi method in this paper are nwe developments of the niche theory and its quantitative analysis method. Taking plants in sandy areas as objects for research, we constructed a theoreitical niche fitness pattern and its computational formulae as well as the simulation method of water fitness process. On the basis of expermiental results, we have done computational analyses and numerical simulation concerned. The simulation result has a very high accuracy, and it tallies with the observed result. This achievement movides the construction o artificial forests in sandy areas with a good quantitative basis.
