A mysterious world at the edge of the ocean: What are lagoons and why are they important?
The lagoon area is an important intersection of the ocean, ecosystems and even human activities. In this globally diverse corner, lagoons not only provide habitat for countless organisms, but also have a profound impact on human life and economic activities. This article will take a closer look at the characteristics of the lagoon area and its importance to the ecosystem.
Lagoons are an extremely important part of coastal ecosystems, yet their true value is often overlooked.
Concept and definition of lagoon area
The lagoon area, also known as the shore or nearshore area, is the portion of the ocean, lake, or river that is close to the shore. Ecologically, lagoonal areas include areas from the high water mark to permanently flooded coastal areas, and the definition of these areas often varies with geographic location and discipline.
In lakes, the lagoon zone is the area where the radiation required for photosynthesis can penetrate deep into the lake bottom. The waters here have higher oxygen concentrations and richer food resources than other deeper waters in the lake, thus supporting a diverse range of organisms.
Biodiversity of the lagoon
In the lagoon area, the diversity of life is on full display. Many fish, invertebrates and aquatic plants depend on the ecological environment here. According to a list of species in the world's largest lakes, more than 93% of species live in shallow lagoon areas and 72% of species are completely dependent on the ecosystem of this area.
The ecosystem in the lagoon area provides habitat for organisms and supports human activities.
Ecological functions of the lagoon area
Lagoon areas play multiple roles in the ecosystem. These areas can filter out pollutants from the water, regulate water levels and promote water flow, thereby effectively protecting the surrounding environment. The existence of wetlands provides a place for many species to reproduce and forage.
The impact of human activities on the lagoon area
With the continuous increase of human activities, the lagoon area faces many challenges. Urban expansion, tourism development, and fishing activities can have negative impacts on these ecosystems. In particular, increased pollutants and the invasion of alien species threaten the biodiversity and ecological balance of the lagoon.
In addition, water level fluctuations and climate change are also major challenges facing the lagoon area. The recovery of the lagoon is limited by human intervention, especially water conservancy projects and construction activities, which have a significant impact on its ecological functions.
The importance of protecting the lagoon area
To protect the biodiversity of the lagoon and build a healthy ecosystem, we need to raise awareness of the importance of these areas and take effective conservation measures. This requires the government, research institutions and non-governmental organizations to work together to develop reasonable planning and management measures.
Protecting the lagoon area is not only about protecting the ecology, but also about protecting the future of our own human race.
As global environmental changes intensify, the importance of lagoon areas becomes increasingly prominent. People need to rethink how to protect these fragile ecosystems while carrying out economic activities? This is a challenge we all face, but also an opportunity for the future?
