| 摘 要： | 农田生物与其环境因素之间关系问题是农业生态系统研究的一个重点问题 ,生物与其所处环境因素之间关系的好坏 ,对生物的生长发育起着重要作用 ,进而影响着农田生态系统的功能发挥。单一生物与其环境因素之间的关系 ,通常是农田生态系统研究的重点。由多种生物组成的生物群落与其环境因素之间的关系 ,由于对农田生态系统的良好发育更起着关键制约作用 ,因而 ,也越来越多地受到研究人员的关注。对农田生态系统生物种群多样性 ,与多种生态环境因子之间关系的研究 ,也由于人们对多样化系统关注程度的提高而显得尤为重要。本文在对已有研究资料系… |

| Abstract: | Study on relationship between populations diversity and its environments,such as light,water,soil,insects and weed in several farmlands ecosystems shows that there is a close connection between populations diversity and their environmental components.Suitable increase of biomass compositions will be more favorable for a better farmland environment,and will inturn improve the development of organisms and the productivity of the system,even if little operation space is existing in one ecosystem.It can also be concluded that the increase of population diversity for a farmland ecosystem is very possible only if the environment permitts.The modification of current farmland ecosystem still has much potentiality. |
| Keywords: | population structural diversity micro-environment farmland ecosystem |
