ecological amplitude
Examples
- Applying the ecological amplitude to nutrition restrictive factors of jialing river in the city zone of chongqing
生态幅在重庆嘉陵江主城段营养盐限制因子中的应用 - These are main problems of eutrophication . at first we select algae which grow under different level of nutrition ( or different development phase in the process of eutrophication ) , domesticate , selecte seed , and culture algae at the lab , and then we obtain dependence of each algae on nutrition and understand information of eco - breadth of nutrition of supplied alga through pure culture under different concentration of nutrition . we find out resource utilization , competition between interspecies and confirm the quantity - effec t relationship between succession of species and nutrition through mixed culture
本文首先选取在不同营养环境下(或富营养化过程的不同发展阶段)生长的藻类物种，在实验室内进行驯化、选种与纯化培养；然后通过不同营养水平的纯藻培养实验，获取不同藻种生长过程对营养物质的依赖行为，从而可以了解每一供试藻种的营养物生态幅信息；再通过对应培养浓度的混合培养试验，以期揭示生物种群间的资源利用与竞争行为，并可进一步确定生物种群的演替与环境营养物之间的量效关系。 - The results show that each algae has its eco - breadth of nutrition , overlap exists between these eco - breadth in a degree , and the range of overlap shows the possibility of co - exist , at the same time , many factors have effect on eco - breadth of nutrition and degree of overlap of eco - breadth
实验结果显示，每一种藻都有各自的营养物生态幅；这些生态幅之间又存在一定程度的重叠，重叠的范围表明它们之间有共存的可能性的大小；而它们各自的营养生态幅及其生态幅之间重叠的程度又受多种因素的影响。
