Description

Technical Field

[0001] The present invention relates to the technical field of forest ecological technology, and more specifically to a design and construction method for restoration and reconstruction of a forest ecosystem. Background Art

[0002] Mining and development will bring many ecological and environmental problems, especially in the hilly areas in the south. Mining will cause serious damage to the mountains and vegetation, not only damaging the natural habitats of wild animals, but also easily causing disasters such as landslides and mountain torrents. Therefore, mine forest ecological restoration is a very important environmental governance issue.

[0003] At present, the forest ecological restoration of abandoned mountainous areas of mines mainly relies on surface vegetation. Vegetation on the surface requires backfilling the abandoned ground in advance and laying a sand and stone soil layer before the grass seeds can be planted to make it grow smoothly. However, the following problems often occur during the construction process:

[0004] The surface of abandoned mountains is deserted, and the laid soil and gravel layers are difficult to maintain. They are susceptible to wind erosion, wind blowing, soil erosion and other problems, which affect the growth and survival of vegetation on the soil and gravel layers. Restoration is difficult and the restoration effect is limited. On the other hand, the solid waste from mines is washed and soaked by rainwater, and the harmful components in it can easily seep into the sand and gravel soil layers, causing soil acid-base pollution, organic toxic pollution and heavy metal pollution, affecting the normal growth and survival of vegetation.

[0005] Chinese Patent: An ecological restoration structure for abandoned mines, authorization announcement number: CN219679200U. This patent document discloses the specific structure and use method of the ecological restoration structure in the prior art. From the above-mentioned disclosed patent content, it can be seen that by using the sand fixation net, the impact of water erosion and wind on sand and grass seeds can be effectively reduced, the growth and survival rate of vegetation can be improved, and the effect of forest ecological restoration can be improved.

[0006] Based on the existing forest ecological technology, this technical solution further improves and perfects the existing technology and proposes a design and construction method for the restoration and reconstruction of the forest ecosystem. It can not only effectively modify and lay the soil sand and stone layer to improve the growth and survival of vegetation, but also optimize and improve the structure of the sand fixation net to improve its use function and facilitate installation and folding.

[0041] Step 2: Laying the sand and gravel soil layer

[0042] The soil layer is laid on the ground of the abandoned land of the forest and mine to form a soil layer for the growth of grass and trees; the laying of the soil layer includes the following specific steps:

[0043] A) Pour mud into the waste residue layer to fully wrap the waste residue with the mud;

[0044] B) then laying a clay layer on the surface of the mud slag layer to form a water-proof layer;

[0045] A soil layer is laid on the surface of the adhesive layer, and the fertility of the soil is improved by fertilizing the soil to complete the laying of the soil layer.

[0046] Step 3: Planting vegetation

[0047] Planting the vegetation grass selected in step 1 in the soil layer laid in step 2, the planting time is the same as the vigorous growth period of the vegetation grass;

[0048] Step 4: Fixing the sandy soil layer

[0049] Use sand-fixing net auxiliary tools to fix the soil layer planted with vegetation, reduce the probability of vegetation and soil layer being eroded by water and wind, and improve the survival rate of vegetation;

[0050] Step 5: Vegetation Restoration and Management

[0052] Regularly sprinkle maintenance water rich in nutrient solution;

[0053] Regular sampling is carried out to observe various growth indicators of vegetation, and non-surviving vegetation is replanted in a timely manner until the vegetation grows normally and the mine ecology is restored.

[0054] By selecting vegetation grass seeds, modifying and paving sandy soil layers, and installing and using sand-fixing nets, we can not only effectively repair and improve the ecological soil of abandoned mountains, but also protect the soil and vegetation, increase the growth and survival rate of ecological vegetation, and thus achieve the restoration and reconstruction of the forest ecological environment.

[0055] like Figure 2 and Figure 3 As shown, the sand-fixing net auxiliary tool includes a fixed rod body 1, a net body 2 and a fixing member 3.
