The dry and hot river valley area is rich in light and heat resources, the climate is hot and there is little rain, the soil erosion is serious, and the ecology is very fragile. The dry and hot river valley area refers to the general term for the river valley belt area with the two basic properties of dryness and heat. The vegetation system on the slope of the dry and hot river valley is relatively fragile and can be easily affected by human and environmental factors, resulting in the destruction of the ecosystem.

[0003] As people's environmental awareness continues to increase, vegetation restoration in dry and hot river valleys has received more and more attention. However, due to the high temperature and low humidity environmental characteristics of dry and hot river valleys, in the process of vegetation restoration in dry and hot river valleys, ecological restoration plants are easily affected by temperature and moisture, resulting in low survival rate and poor ecological restoration effect. The effect of auxiliary vegetation restoration on slopes in dry and hot river valleys is poor.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown, a multi-layer protective structure for slope vegetation restoration in a dry-hot valley area in one embodiment of the present invention includes: a slope body 1, multiple groups of soil consolidation and moisture retention structures 2, and multiple groups of greening restoration structures 3.

[0032] like Figures 1 to 4 As shown, multiple groups of soil consolidation and moisture retention structures 2 are fixedly assembled on the top of the slope 1, and the soil consolidation and moisture retention structures 2 include soil consolidation limiters 201, which are fixedly assembled on the top of the slope 1. The soil consolidation limiters 201 are used to perform soil and water conservation and moisture retention treatment on the slope 1.

[0033] like Figures 3 to 6 As shown, the soil fixing limiter 201 is composed of a pair of side plates 2011, a soil fixing front plate 2012, a rear plate 2013 and a supporting bottom plate 2014. The pair of side plates 2011 are arranged between the soil fixing front plate 2012 and the rear plate 2013, and the supporting bottom plate 2014 is arranged at the bottom of the pair of side plates 2011.

[0034] It is worth noting that the height of the soil fixing front plate 2012 is lower than that of the rear plate 2013. The cooperation between the soil fixing front plate 2012 and the rear plate 2013 makes the side of the soil fixing limiter 201 inclined, so as to facilitate the assembly of the soil fixing limiter 201 on the upper surface of the slope 1.

[0035] Specifically, seepage holes are provided on the soil-fixing front plate 2012 and the rear plate 2013. The seepage holes guide the multiple soil-fixing position-limiting members 201, thereby playing a role of synchronously moisturizing the multiple soil-fixing position-limiting members 201.

[0036] like Figure 1 to Figure 2 As shown, a diversion protection kit 204 is fixedly installed in the seepage hole. The diversion protection kit 204 plays the role of assembly fixation and position limiting protection for the seepage pipe 205, reducing the risk of deformation and damage of the seepage pipe 205 due to external force during actual application.

[0037] like Figure 1 to Figure 2 As shown, a plurality of uniformly distributed seepage pipes 205 are fixedly mounted in the diversion protection kit 204. The plurality of seepage pipes 205 connect and conduct the plurality of soil fixing limiters 201, thereby facilitating the seepage conduction of the water storage and moisture retention layers 208 in the plurality of soil fixing limiters 201.

[0038] like Figure 1 to Figure 2 As shown, both sides of the diversion protection kit 204 are fixedly connected with anti-blocking filter screens 206, and the anti-blocking filter screens 206 are arranged in cooperation with the seepage pipe 205. By arranging the anti-blocking filter screens 206 at both ends of the seepage pipe 205, the anti-blocking filter screens 206 can prevent the seepage pipe 205 from blocking, thereby ensuring the stability of the seepage pipe 205 in use.

[0039] like Figures 1 to 4As shown, the side of the soil-fixing and limiting member 201 close to the slope 1 is filled with a water-proof and moisturizing layer 202. The water-proof and moisturizing layer 202 supports and limits the cultivation bottom layer 207, the water storage and moisturizing layer 208 and the cultivation matrix layer 203 and fixes the soil and keeps the moisture.

[0040] Specifically, the water-insulating and moisture-retaining layer 202 is composed of waste mineral residue, waste ceramics, bentonite and cement concrete. The water-insulating and moisture-retaining layer 202 plays a role of water-insulating and moisture-retaining for the cultivation bottom layer 207 and the slope 1, thereby improving the moisture-retaining effect of the water-storage and moisture-retaining layer 208.

[0041] like Figures 1 to 3 As shown, the soil-fixing stopper 201 cooperates with the water-isolating and moisture-retaining layer 202 to form a soil and water conservation cavity, and the soil and water conservation cavity is filled with a cultivation matrix layer 203. The cultivation matrix layer 203 provides the cultivated plants 302 with the nutrients and soil required for planting.

[0042] Specifically, the cultivation substrate layer 203 is a mixture of soil, peat, microbial residue, perlite and compound fertilizer, and provides the cultivated plants 302 with the nutrients required for cultivation.

[0043] like Figure 1 to Figure 2 As shown, an inclined angle α is formed between the upper surface of the cultivation matrix layer 203 and the horizontal plane, and the height of the cultivation matrix layer 203 close to the soil fixing front plate 2012 is higher than the height of the other side, and the range of the inclined angle α is 10° to 20°. By setting the upper surface of the cultivation matrix layer 203 to be inclined inward, the stability of the cultivation of the cultivated plants 302 is ensured.

[0044] like Figure 3 to Figure 4 As shown, the soil and water conservation cavity is filled with a cultivation bottom layer 207. The cultivation bottom layer 207 supports and assists the water storage and moisture retention layer 208 in moisture retention and water storage.

[0045] Specifically, the cultivation bottom layer 207 is composed of soil, water retaining agent and plant ash.

[0046] like Figure 3 to Figure 4 As shown, a water storage and moisture retention layer 208 is filled between the cultivation bottom layer 207 and the cultivation matrix layer 203, and the seepage holes on one side of the soil-fixing front plate 2012 are connected to the water storage and moisture retention layer 208. The water storage and moisture retention layer 208 plays a role in storing and moisturizing the soil-fixing limiter 201, thereby ensuring the moisture required for the cultivation process of the cultivated plants 302 and improving the cultivation survival rate of the cultivated plants 302.

[0047] The water storage and moisture retention layer 208 is composed of clay, ceramsite, water-absorbing resin and plant fiber. The water storage and moisture retention layer 208 plays a role of water storage and moisture retention, reduces the risk of water evaporation of the cultivation matrix layer 203 due to the influence of the external temperature, and improves the planting survival rate of the cultivated plants 302.

[0048] like Figures 5 and 6 As shown, multiple groups of greening restoration structures 3 are assembled above the soil-fixing stopper 201, and the greening restoration structures 3 include multiple groups of cultivation partitions 301, and both sides of the multiple groups of cultivation partitions 301 are fixedly connected to the inner wall of the soil-fixing stopper 201. The soil-fixing stopper 201 is spatially separated by the cultivation partitions 301. At the same time, the soil-fixing protective net 303 can be assembled and fixed by the cultivation partitions 301.

[0049] Specifically, the cultivation partition 301 divides the cultivation substrate layer 203 into a plurality of vegetation cultivation grooves, through which the cultivation plants 302 are planted.

[0050] like Figure 1 As shown, multiple vegetation cultivation grooves are planted with cultivated plants 302. The cultivated plants 302 are used to restore vegetation on the slope 1.

[0051] It is worth noting that the cultivated plants 302 are nitrogen-fixing broad-leaved trees or shrubs, and the planting density of the cultivated plants 302 is 1000-1200 plants / h㎡.

[0052] like Figures 5 and 6 As shown, soil-fixing protection nets 303 are evenly distributed in multiple vegetation planting grooves, and the soil-fixing protection nets 303 are mounted on the outside of the cultivated plants 302.

[0053] Specifically, a plurality of diversion irrigation holes are provided above the soil-fixing protection net 303. By providing the diversion irrigation holes above the soil-fixing protection net 303, not only the ventilation and air permeability of the cultivation matrix layer 203 can be ensured, but also the direct sunlight area of ​​the cultivation matrix layer 203 is reduced, thereby reducing the evaporation of water in the cultivation matrix layer 203 due to sunlight.

[0054] Preferably, the soil-fixing protection net 303 is woven from polypropylene and polyester fibers.

[0055] When in use, multiple soil-fixing stoppers 201 can be fixedly assembled on the top of the slope 1, and a water-insulating and moisturizing layer 202 can be laid on the side of the soil-fixing stoppers 201, and then the cultivation bottom layer 207, the water-storage and moisturizing layer 208 and the cultivation matrix layer 203 are sequentially filled into the soil and water conservation cavity. Subsequently, the soil-fixing protective net 303 is laid on the top of the cultivation matrix layer 203, and the cultivation partition 301 can be fixedly assembled in the soil-fixing stoppers 201 according to the size of the cultivated plants 302 and the cultivation density requirements, and the cultivation matrix layer 203 is divided into multiple vegetation planting grooves, and the cultivated plants 302 are planted in the vegetation planting grooves.

[0056] During use, the cultivation matrix layer 203 can provide a cultivation foundation for the cultivated plants 302, and the cultivation matrix layer 203 and the water storage and moisture retention layer 208 can play a role in water storage and moisture retention. During the water storage and moisture retention process of the water storage and moisture retention layer 208, the cooperation of the multiple diversion protection kits 204, the seepage pipes 205 and the anti-blocking filter 206 can be used to infiltrate the multiple soil-fixing limiters 201, thereby synchronously fixing the soil and moisturizing the multiple soil-fixing limiters 201.

[0057] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
