What are the measures to mitigate grazing on grassland communities?

Grazing is a kind of pastoralism behavior of livestock in grassland, which is a production method in which herbivores under artificial control collect pasture grass on grazing land and convert it into livestock products. In this mode of production, grazing livestock live on grassland, on the one hand, they collect pasture grass and take in nutrients from the grazing land; On the other hand, livestock are properly exercised in grazing and are exercised in sunlight and various climatic environments to maintain their health and growth.

Therefore, grazing is the main production mode for livestock to rely on the abundant nutrition and suitable living conditions provided by grazing, and under proper feeding management, the forage produced by light energy is converted into livestock products to achieve the purpose of grassland production. The impact of grazing on grasslands is manifold.

Grazing livestock have an impact on grassland through feeding, trampling and excretion (manure and urine), which affect the yield, quality and botanical composition of grassland pasture; Conversely, these factors are affected by the pasture properties of the grassland. Therefore, it is difficult to distinguish between them in terms of cause and effect.

In addition, many impacts are directly or indirectly affected by environmental conditions (climate and land).

The chef's words must be to enhance the protection of this wetland, and then make a fence for your exercise, and then carry out a playground restoration.

This paper discusses the impact of grazing on grassland from the perspectives of plant adaptation strategies and the effects of grazing on community structure and function.

Grazing livestock have an impact on the grassland through feeding, trampling, burrowing, and excretion (manure and urine), which affect the yield, quality, and botanical composition of the grassland: conversely, these factors are affected by the pasture properties of the grassland. Therefore, it is difficult to distinguish between them in terms of cause and effect.

In addition, many impacts are directly or indirectly affected by environmental conditions (climate and land). (1) Leaf harvesting Livestock grazing in grasslands, mainly foraging on forage stems and leaves, thus affecting forage yield, forage nutrients, forage reproduction, and grassland botany. 1.

Effect of leaf picking on forage yield Grazing livestock feed on forage stems and leaves, obtain nutrients from grazing grassland, and the frequency and level of forage intake directly affect the fractionation and leaf volume index of forage. Leaves are the organs of forage to produce nutrients, and the leaf accumulation is the same as light, temperature and other factors, which directly affect the speed of photosynthesis of forage.

Overgrazing refers to the fact that in grassland ecosystems, grazing exceeds the carrying capacity of the area, and this destructive behavior has a huge impact on grassland ecosystems. The following are the effects of overgrazing on grassland ecosystems:

Reduction of grassland vegetation cover: Overgrazing leads to overgrazing that removes the newly grown part of grassland vegetation, reduces grassland cover, and reduces the self-healing ability of grassland communities, thus negatively affecting the stability and health of grassland ecosystems.

Damage to soil structure: In the case of overgrazing, the hooves of livestock and the roads formed by excessive travel will destroy the structure of grassland vegetation and upper soil, resulting in soil tightening in the grassland, resulting in reduced water permeability and aeration, as well as runoff and soil erosion.

Reduced water quality: Overgrazing can lead to a decrease in grassland vegetation accessibility, reduce the impact of plum on vegetation roots, and when it rains, water flows rapidly into rivers and lakes, reducing the number and activity of important nutrients, organic matter, and spindle-shaped perturbation capillaries in the soil, resulting in a decline in water quality.

Destruction of grassland biodiversity: Grassland ecosystems are typical ecosystems, and in the case of overgrazing, the species and number of plants will be significantly reduced, and biodiversity will be severely damaged, resulting in the balance of ecosystems being affected, and the number of species and habitats dependent on grassland ecosystems will also be reduced accordingly.

In summary, overgrazing will lead to the reduction of grassland coverage, the destruction of soil structure, the decline of water quality, the loss of grassland biodiversity and other negative impacts, accelerate the process of grassland degradation and soil desertification, and affect the balance and health of grassland ecosystems.

The area and grass yield of a certain area of grassland are relatively fixed, a certain area and a certain amount of grass can only support a certain number of livestock, overgrazing exceeds the carrying capacity of the grassland and makes the grassland plants can not return to normal growth, caused.

Grassland degradation. Even semi-desertification, desertification.

Overgrazing is often caused by the arrogance of livestock, and the density is too high.

Soil compaction. And the reduction of grass production may also lead to:

Grassland vegetation. Structural destruction, i.e., a rapid decline in the population of pasture available to livestock, while the population of other plants that are not available to livestock flourishes, ultimately hindering the development of pastoralism.

I'm a high school student, so let's use my high school knowledge to answer! I hope it helps: there is a competitive relationship between grass and grass, which is easy to understand, and the land is limited!

Therefore, when there is a certain amount of grass, it will maintain a stable number, first set it to k, and the characteristics of the population are that the growth rate is the fastest when k 2, so it is just right to eat half of the grazing, because the grass grows the fastest at this time, and it is called overgrazing if it exceeds this limit
