Environmental problems, causes, and measures in the upper, middle and lower reaches of the Yangtze R

The main problem of the Yangtze River is flood control in the middle and lower reaches of the Yangtze River. River improvement in the middle and lower reaches and Dongting Lake, strengthening flood control management and non-engineering flood control measures, strengthening the construction of embankments in the middle and lower reaches, building reservoirs on tributaries, and preventing soil erosion.

Yangtze River: Upstream: Water.

Soil erosion. Solve the problem of source application: return farmland to forest and grassland, and plant trees.

Middle and lower reaches: sediment accumulation, flood disasters, water pollution.

Solution: return farmland to lakes and prevent water pollution.

Yellow River: Upstream: Severe desertification, flooding.

Solution: Strengthen the construction of ecological environment and dredge rivers.

Midstream: Soil erosion.

Solution: Carry out comprehensive management of soil and water conservation.

Downstream: above-ground river, Lingxun.

Solution: Strengthen the embankment and dredge the river.

The main problems of the Yangtze River and their solutions.

Upstream: Soil and water flows.

Measures: Afforestation.

Middle and lower reaches: sediment accumulation, flood disasters, water pollution.

Measures: Returning farmland to lakes, reinforcing river dams, and preventing water pollution.

The main ecological problems and solutions of the main stream of the Yellow River.

Upstream: Severe desertification, flooding.

Measures: Strengthen ecological and environmental governance.

Midstream: Severe soil erosion.

Measures: Carry out integrated management of soil and water conservation.

Downstream: Above-ground rivers are severe.

Measures: Reinforcement of levees or dams.

Yellow River: Soil erosion and above-ground rivers. upstream construction of water conservancy projects; soil and water conservation in the midstream; Downstream reinforcement of the embankment.

Yangtze River: Floods. afforestation of vegetation in the middle and upper reaches to increase vegetation coverage; In the middle and lower reaches, the embankment was reinforced, the bend was straightened, and the river channel was dredged.

The Yangtze River is the largest river in China, and its upstream, middle and lower reaches have many problems. Among them, these problems are often brought about by human activities, which may include industrialization and urbanization. The development of coastal areas, the construction of water conservancy projects, and the deterioration of the ecological environment are also important factors leading to problems in the Yangtze River.

The management of the ecological environment and water resources in the entire Yangtze River basin is a comprehensive, complex and long-term task.

In the upper reaches of the Yangtze River, soil erosion is often a common problem. Deforestation and over-exploitation can cause significant damage to river ecosystems, often causing materials such as soil, rocks and boulders to enter rivers with heavy rainfall, resulting in rapid river flows, increased pollution, and ultimately major flooding. Therefore, the relevant departments in the upper reaches of the Nagahandpi River should give priority to forest protection measures and soil and water conservation.

In addition, efforts should be made to strengthen the construction of water conservancy projects, including strengthening barrages, reservoirs, embankments, river dredging, and the construction of water and sediment storage projects, so as to bring better protection and development to the areas along the rivers.

The problems in the middle reaches of the Yangtze River are mainly related to water management and water pollution. With the development of urbanization and the increase of economic activities, the river water resources in the middle reaches of the Yangtze River are facing serious pressure. Therefore, the relevant departments should strengthen the management of water resources, formulate more scientific and reasonable water resources management policies, rationally allocate and utilize water resources, and strictly control and punish illegal occupation of water resources.

In addition, the problem of water pollution can be solved by strengthening supervision and investing funds to carry out water pollution control.

The problems in the lower reaches of the Yangtze River are mainly related to the protection of water resources and the deterioration of the ecological environment. The lower reaches of the Yangtze River are one of the most important economic regions in China, but it is also highly populated and industrialized. Therefore, the protection of water resources is very important, and it is necessary to strictly control and regulate discharge, as well as strengthen the treatment and management of garbage in areas along the river.

The deterioration of the ecological environment is also one of the problems in the lower reaches of the Yangtze River, and in this regard, the relevant departments can promote ecological restoration and adopt sustainable measures for agricultural production to achieve a balance between economic development and ecological protection.

To sum up, the problems existing in the upper, middle and lower reaches of the Yangtze River are very complex and long-term tasks. It is necessary for the state and relevant departments along the Yangtze River to actively explore and promote a series of relevant measures to strengthen the cultural protection and ecological construction of the Yangtze River area, and promote the balanced development of economic development and ecological environment. <>
