赤潮藻类温度生态幅的定量表达模型研究

The quantitative study on ecological amplitude of sea temperature of algae

生态幅在重庆嘉陵江主城段营养盐限制因子中的应用

Applying the Ecological Amplitude to Nutrition Restrictive Factors of Jialing River in the City Zone of Chongqing

广生态幅的物种适应性好于狭生态幅的；

The adaptability of species with wide ecological range is superior to that of the narrow-ecological rang ;

试验结果表明：（1）沙棘有一定的耐旱能力，为广生态幅植物；

The following results are obtained : ( 1 ) Seabuckthorn has certain drought resistant capability , it is a plant of vastly ecological amplitude .

为了解重庆嘉陵江主城段营养盐与藻类的关系，探索富营养化发生的机理，笔者运用生态学中的生态幅原理对该段水体营养盐限制因子进行了系统分析。

In order to study the relationship of nutrition and algae , and search after the mechanism of eutrophication , the ecological amplitude principle is used to study the nutrition restrictive factors .

差不嘎蒿生态幅广，从流动沙丘背风坡到固定沙丘均有分布，但其最适宜的生境是水分条件较好、有些风蚀与沙埋的半流动、半固定沙地。

Its ecological amplitude is relatively wide , it distributes from the leeward of shifting dunes to fixed dunes , but its favourable habit is semi-shifting and semi-fixed dunes which have better water condition and sand burying problem .

生态幅宽、适应强的森林类型的生物多样性比生态幅窄、适应弱的丰富。

The ecology breadth , the strong adapting forest type biodiversity must be higher than the ecology narrow , adapting weakly .
