How to protect the soil and reduce soil erosion? The more words there are, the bigger my reward will be. (600 best)

1. Use less plastic bags and disposable foam lunch boxes: they will cause white pollution, please refer to "White Pollution" for details

2. Do not take soil at will: if we Digging soil in wild areas such as roadsides, hillsides, and pastures

not only destroys the original vegetation, but also takes away the surface soil, which will become larger and larger under the erosion of rain and wind, resulting in grassland Degradation can even cause severe ecological events such as mountain mudslides and landslides, resulting in serious consequences. "A long embankment that is thousands of miles long ends in an ant nest." We should avoid even small acts of vandalism, and at the same time advocate planting trees and grass, protecting roads and slopes, and beautifying our living space.

3. Do not throw away batteries randomly

4. Do not abuse chemical fertilizers: Excessive use of chemical fertilizers will not only pollute water resources, but also harden the soil, affecting the ability of crops to retain water and nutrients. There is oxygen absorption.

Cultivated land protection:

(1) 1. Strictly control the conversion of cultivated land into non-cultivated land;

2. The state implements a compensation system for occupied cultivated land;

3. The state implements a basic farmland protection system;

4. Promote land development, reclamation and consolidation.

The quality protection of cultivated land includes the following aspects:

1. The state formulates measures to protect the quality of cultivated land, such as preventing soil erosion, desertification, salinization, and barrenness of cultivated land;

2. Realize the environmental protection of cultivated land.

Land consolidation

An important aspect of farmland protection is to vigorously promote land development and consolidation. Land consolidation is an activity that uses engineering, biological and other measures to comprehensively improve fields, water, roads, forests and villages, increase the effective cultivated land area, and improve land quality and utilization efficiency.

Treatment of water and soil erosion:

In order to protect, improve and rationally utilize the water and soil resources in hilly areas and windy and sandy areas, it is necessary to comprehensively control water and soil erosion. The main measures for comprehensive management include agricultural technical measures for soil and water conservation, vegetation construction measures for soil and water conservation, and engineering measures for soil and water conservation. The design and configuration of various treatment measures must follow the following principles:

① Give top priority to regulating surface runoff and reducing slope runoff. To this end, it is necessary to improve soil permeability and water-holding capacity; build engineering facilities to store runoff or safely discharge runoff on slopes to change small terrain; use vegetation to regulate and absorb surface runoff.

②Improve soil corrosion resistance. Measures such as changing the small terrain, applying more organic fertilizers, planting crops with strong soil-fixing roots, and applying soil polymerizers can be adopted.

③ Increase vegetation coverage and improve the protective effect of vegetation. It can create soil and water conservation forests to conserve water sources, regulate surface runoff and prevent erosion.

④ For land that has been eroded, in addition to preventing further erosion, measures to improve the physical and chemical properties of the soil and increase soil fertility should be supplemented to combine land protection and improvement.

⑤In hilly areas, comprehensive management should be carried out based on small watersheds as units, so as to combine forest and grass measures with engineering measures, combine slope control with gully control, and combine management with development to achieve centralized management. , continuous management, quick results.

⑥Carry out water and soil conservation planning and design according to local conditions, and adopt comprehensive management measures to fully consider the natural conditions, water and soil erosion characteristics and socio-economic conditions of different regions.

⑦Reflect the principle of optimal ecological and economic benefits. To carry out comprehensive management of soil and water conservation, it is necessary to compare multiple options and select the one with the best ecological and economic benefits.
