这关键区别在贫营养和富营营养的湖泊之间贫营养的湖泊含有非常低的营养成分,而富营养湖泊则含有大量的营养成分。
世界各地都有许多湖泊。它们因地理位置,污染率,环境条件和养分内容而有所不同。基于营养含量,可以将湖泊归类为贫营养湖泊,中营养和富营营养的湖泊。湖泊的营养状态提供了有关污染状况以及湖泊所在区域的地理细节的可靠信息。当区分贫营养和富营营养的湖泊时,所考虑的主要营养素是Nitrogen and Phosphorus。

什么是贫营养湖泊?
贫营养湖指的湖泊very less nutrient composition. Thus, the levels of Nitrogen and Phosphorus in an oligotrophic lake are very low. Highly oxygenated water can be observed in the oligotrophic lakes. Hence the oxygen levels of the water are comparatively high. The water in oligotrophic lakes is also very cold. This increases the dissolution of oxygen in the water, further increasing the oxygen levels. The bottom water of the oligotrophic lake makes it difficult for the survival of most aquatic organisms due to very low temperature. The fish found in oligotrophic lakes include whitefish and trout.
贫营养湖中的藻类含量非常低,因为它们没有足够的营养条件。因此,光穿透性很高,并且没有产生的气味。
这decomposition process in oligotrophic lakes is very slow as there are very fewer分解器由于养分的可用性较小。贫营养湖泊的存在还表明,该区域中含有化学物质的污染水平和表面径流较少。
什么是富营营养的湖泊?
Eutrophic lakes are the lakes that have an excessive algal growth due to the high content of nutrients. Eutrophication is the process that creates this kind on lakes. In eutrophic lakes, there is a high content of Nitrogen and Phosphorus. Since eutrophic lakes are rich in nutrients; they support for the increased growth of algal forms such as小球藻and螺旋藻。
这增加了生物氧的需求。因此,湖底通常是缺氧的,因为它没有得到足够的氧气。由于Excel藻类开花的生长,光渗入湖泊的渗透也减少了。分解率在富营养化的湖泊中很高,因此,这些湖泊中有一种气味。
贫营养和富营营养的湖泊之间有什么相似性?
- Both types of lakes depict the nutrient levels of the aquatic environments.
贫营养和富营营养的湖泊有什么区别?
Oligotrophic and eutrophic lakes are two types of lakes defined based on the nutrient composition of the lake. Oligotrophic lakes do not contain a high level of nutrients. Hence, they contain oxygen-rich clean water. On the other hand, eutrophic lakes contain high levels of nutrients mainly nitrogen and phosphorus hence, they have increased growth of algal blooms. This is the key difference between oligotrophic and eutrophic lakes. Furthermore, another notable difference between oligotrophic and eutrophic lakes is that the eutrophic lakes have a high oxygen demand and high rate of decomposition.

摘要 - 贫营养与富营营养的湖泊
湖泊的营养水平根据湖泊的营养成分定义。贫营养湖泊中存在分钟的营养成分。相比之下,富营营养的湖泊中有高浓度的养分。此外,在富营养的湖泊中,氮和磷具有很高的水平。由于农业土地上的地表径流水过多以及由于污染而导致的富营营养湖泊。因此,富营养化的湖泊富含藻类种群,并导致死水有机物的快速分解。相比之下,贫营养的湖泊的藻类形式较少或没有藻类形式,并且含有透明的冷水。这是贫营养和富营营养的湖泊之间的差异。
