通过采用合适的养护方案，达到保护植物群落的目的，并使人工植物群落向自然

By adopting appropriate conservation programs, the purpose of protecting plant communities is achieved, and artificial plant communities are gradually transitioned to natural communities. Finally, a biological community that can be self-renewing, healthy, stable and efficient can be formed. <br><br>Mine vegetation restoration should be based on different types of mine destruction and their degree, choose one or more vegetation restoration methods according to local conditions, take into account the production and life of the mine and surrounding communities, and should fully coordinate the ecological, economic and social development of the area. <br><br>Soil is an indispensable condition for plant growth and the basis for plant growth and development. It can fix plants and maintain normal life activities of plant roots, so that the environment has a relatively stable and suitable temperature. It can also provide the water and fertilizer needed for plant growth. Plants can absorb N, P, K, Ca, Zn, S and other elements from the soil. The air in the pores of the soil can also provide oxygen for the life activities of plant roots. <br><br>The growth of plants is inseparable from their own photosynthesis, and light intensity is the main energy source for the photosynthesis of vegetation in the mining area. Because different plants have different requirements for light intensity, some plants are shade-tolerant, and some plants like the sun. The <br><br>temperature also has a great influence on plant growth. The enzyme activity at different temperatures is also different, and the growth activity of the plant varies with temperature. The changes are constantly changing. <br><br>Generally, plants contain 60% to 90% water, which is the source of plant life activities. The absorption and transformation of nutrients in plants, as well as respiration and transpiration, are inseparable from the participation of water. <br><br>Then evaluate the land and soil of each type of mine site. Different types of land correspond to different vegetation restoration methods, planting patterns and suitable plant types,<br><br>The first step is to prepare the land. The flat ground adopts the method of cavernous land preparation. The cavernous land preparation is a circular or rectangular pit, so that the cave surface is flat or slightly inclined inward with the original slope surface, the cave diameter is 40.5cm, and the depth is kept within 25-40cm. For soil slopes, cavernous land preparation, horizontal belt land preparation or fish scale pit land preparation methods are used; for rock slopes, cave or fish scale pit land preparation methods are used. The bandwidth of the horizontal belt preparation method varies according to the site conditions, generally 10-20m. When the slope is large, the bandwidth can be smaller, and when the slope is small, the bandwidth should be larger. The depth of site preparation is 30-50cm. The site preparation of fish scale pits is to excavate suitable fish scale pits by small blasting on the side slopes where conditions permit, and to fill the pits with planting shrubs and creeping plants with a depth of 40-60cm. <br>The second is species selection. The flat land is suitable for planting forages or green manure plants first, and after the soil is slightly improved, then planting native plants; slopes should choose vegetation with developed root systems, easy survival, drought tolerance, and strong adaptability to the environment.

By adopting appropriate conservation programmes, the goal of protecting plant communities and gradually transitioning artificial plant communities to natural communities results in a biocommunity that can be self-renewing, healthy, stable and efficient.<br><br>Mine vegetation restoration should be based on different types of mine damage and the extent of damage, according to local conditions to choose one or more methods to restore vegetation, taking into account the production and life of the mines and surrounding communities, should fully coordinate the ecological, economic and social development of the region,<br><br>Soil is an essential condition for plant growth and the basis for plant growth and development. It can fix plants and maintain normal life activity of plant roots, so that the environment has a relatively stable and suitable temperature. It can also provide the moisture and nutrients needed for plant growth, which can absorb elements such as N, P, K, Ca, Zn, S, etc. from the soil. The air in the pores in the soil also provides oxygen for the life activities of the plant roots.<br><br>Plant growth can not be separated from its own photosynthesis, light intensity is the mining vegetation photosynthesis of the main energy source. Because different plants have different needs for light intensity, some plants are yin-resistant, and some plants are happy to be yang,<br><br>Temperature also has a great influence on plant growth, the activity of enzymes at different temperatures is also different, plant growth activity also changes with the temperature changes.<br><br>The general plant contains 60% to 90% of the water, water is the source of plant life activities. The absorption and transformation of nutrients in plants, as well as the respiration and steaming effect, are inseparable from the participation of water.<br><br>Then the soil soil of the land type of each mining area is evaluated. Different types of land correspond to different vegetation restoration methods, planting patterns and plant types suitable for planting,<br><br>The first step is to do the whole thing. Flat use of cave-like ground-like method, cave-shaped whole for round or rectangular pits, so that the cave surface and the original slope flat or slightly inward tilt, hole diameter 40.5cm, depth remained within 25-40cm. The soil slope surface adopts the method of cave-like whole land, horizontal belt whole land or fish scale pit whole ground, while the rock slope surface adopts the method of cave or fish scale pit whole ground. The bandwidth of the horizontal belt-grounding method varies according to the ground conditions, generally 10 to 20m, when the slope is larger, the bandwidth can be smaller, when the slope is small, the bandwidth should be larger. The depth of the whole land is 30 to 50 cm. Fish scale pits are made on a conditional slope with small blasting to dig suitable fish scale pits, and to fill the pits to plant Joe shrubs and vine-climbing plants at depths of 40-60cm.<br>The second is the choice of species. The flat land is suitable for planting grass or green fertilizer plants first, and then planting native plants after the soil has been improved, and the slope should choose vegetation with developed roots, easy to survive, drought-tolerant and more adaptable to the environment.

Through the use of appropriate conservation programs, to achieve the purpose of plant community protection, and make the artificial plant community gradually transition to the natural community, and finally form a self renewing, healthy, stable and efficient biological community.<br>According to different types and degrees of mine damage, one or more methods of vegetation restoration should be selected according to the local conditions, and the production and life of the mine and surrounding communities should be considered. The ecological, economic and social development of the area should be fully coordinated,<br>Soil is an essential condition for plant growth and the basis for plant growth and development. It can fix the plant, keep the normal life activity of the plant root, and make the environment have a relatively stable and appropriate temperature. It can also provide water and fertilizer for plant growth, and plants can absorb n, P, K, CA, Zn, s and other elements from the soil. The air in the pores of soil can also provide oxygen for the life activities of plant roots.<br>The growth of plants is inseparable from their own photosynthesis, and the light intensity is the main energy source for photosynthesis of the vegetation in the mining area.

Water plays an important role in the absorption and transformation of nutrients, respiration and transpiration.<br>Then the soil of each type of mining site is evaluated. Different site types correspond to different vegetation restoration methods, planting patterns and suitable plant types,<br>First of all, land preparation should be carried out. The method of hole shaped land preparation is adopted for the flat land. The hole shaped land preparation is circular or rectangular, so that the hole surface is flat with the original slope or slightly inclined inward, the hole diameter is 40.5cm, and the depth is kept within 25-40cm. The soil slope adopts the method of hole shaped land preparation, horizontal belt land preparation or fish scale pit land preparation; the rock slope adopts the method of hole shaped or fish scale pit land preparation. The bandwidth of horizontal belt preparation method varies with site conditions, generally 10-20 M. when the slope is large, the bandwidth can be smaller, the slope is small, and the bandwidth should be larger. The depth of land preparation is 30-50cm. Fish scale pit preparation is to excavate appropriate fish scale pit by small blasting on the slope where conditions permit, and fill the pit with trees, shrubs and climbing rattan plants, with a depth of 40-60cm.<br>The second is species selection. The flat land is suitable for planting grass or green fertilizer plants first, and then planting local plants after the soil is slightly improved; the slope should select vegetation with developed root system, easy to survive, drought resistance and strong adaptability to the environment.<br>
