[0041] Embodiment 1:

[0042] The present invention provides a stable vegetation system for ecological restoration of mining wasteland. Please refer to Figures 1-12 , which includes a restored vegetation management unit and a restoration management platform. The input end of the restored vegetation management unit is connected with a wasteland parameter unit, a meteorological induction unit, a vegetation planning unit, and a root monitoring unit. The output end of the restored vegetation management unit is connected with a vegetation maintenance unit, a data output unit, and a vegetation anomaly warning unit;

The input end of the meteorological induction unit is signal - connected to the meteorological platform. The input end of the root monitoring unit is signal - connected to the root monitor. The output end of the vegetation maintenance unit is signal - connected to the irrigation system set in the mining wasteland. The output ends of the data output unit and the vegetation anomaly warning unit are both signal - connected to the restoration management platform;

[0044] The root monitoring device includes a positioning signal ring 1 fixedly wrapped around the main trunk of the vegetation. A growth monitoring sleeve 3 is fixedly connected to the lower end of the positioning signal ring 1. A companion root ring 2 fixedly wrapped around the outer end of the vegetation root ball is fixedly connected to the lower end of the growth monitoring sleeve 3. A plurality of evenly distributed elastic pulling wires are fixedly connected between the upper and lower inner walls of the growth monitoring sleeve 3. And in the initial state, the growth monitoring sleeve 3 maintains a contracted state under the action of the elastic pulling wires. A pressure sensor is fixedly connected to the lower inner wall of the growth monitoring sleeve 3. The output end of the pressure sensor is signal-connected to the root monitoring unit. Through the settings of the root monitoring unit and the root monitoring device, after the vegetation system plans ecological restoration according to the data of the mining waste land, it can conduct regional monitoring on the planted vegetation roots, can effectively judge the rationality of the ecological restoration plan according to the growth state of the vegetation roots, and can also adjust the maintenance process of the ecological restoration in a timely manner according to the growth data of the vegetation roots, providing reliable reference data in the subsequent continuous ecological restoration construction process, having biological representativeness that conforms to the mining waste land, and also promoting and assisting the growth of the vegetation roots through the settings of the companion root ring 2 and the growth monitoring sleeve 3, effectively improving the rooting strength of the vegetation and the stability of the vegetation growth on the mining waste land, so as to ensure the rationality and controllability of the vegetation system, thereby assisting ecological restoration personnel to promote the mining waste land to achieve the expected ecological restoration goal and shortening the ecological restoration cycle.

[0045] Please refer to Figures 1-3 , the root monitoring unit includes a root monitoring processing module. The input end of the root monitoring processing module is connected with a girth data module and a depth data module. The output end of the root monitoring processing module is signal-connected to the restored vegetation management unit. The input ends of the girth data module and the depth data module are both signal-connected to the pressure sensor. The settings of each module of the root monitoring unit can realize the comprehensive monitoring and collection of the vegetation root data, so as to judge the growth adaptability of this variety of vegetation on the mining waste land, and then adjust the ecological restoration plan of the vegetation system, reduce the cost in the ecological restoration construction process, and promote the efficiency of ecological restoration.

[0046] Please refer to Figure 4 and Figure 5 , a plurality of evenly distributed root protection support bars 41 are fixedly connected to the lower end of the companion root ring 2. A root guiding ring 4 is fixedly connected to the lower end of the root protection support bars 41. The settings of the root protection support bars 41 and the root guiding ring 4 can further guide the roots of the vegetation downward, increase the depth of its root growth, so as to ensure the anti-risk function of the vegetation, improve the survival rate of the vegetation, and ensure the sustainable function of ecological restoration.

[0047] Please refer to Figures 1-3 and Figure 11 、 Figure 12, the positioning signal ring 1, the root - accompanying ring 2, the growth monitoring sleeve 3, the root - guiding ring 4, the root - protecting strip 41 and the isolation sheet 5 are all made of elastic materials. While monitoring the root system data of vegetation, they can reduce the degree of restriction on root growth and the degree of damage to the roots. Moreover, they can make the root monitoring device adaptable to different states of vegetation roots, ensuring the validity of the detection data.

[0048] Please refer to Figures 1-3 and Figure 11 、 Figure 12 , a plurality of locking buckles are fixedly connected to the outer end of the positioning signal ring 1, and a locking hoop is slidably connected inside the locking buckle, ensuring the stability of the positioning signal ring 1 fixed on the main trunk of the vegetation. When the growth monitoring sleeve 3 and the root - guiding ring 4 grow along with the roots, it ensures the validity of data monitoring.

[0049] Please refer to Figures 1-12 , after the environmental data collection of the mining waste land is completed and the vegetation construction plan for the ecological restoration of the mining waste land is planned. First, select a part of the location of the mining waste land as an ecological restoration test area to form a vegetation planting network, conduct verification planting for various vegetations, and divide the monitoring areas for different varieties of vegetations. The root monitoring devices are selected and set according to the partition quantity for the vegetations planted in the monitoring areas. All the data of the vegetation construction plan are transmitted to the restored vegetation management unit through the data of the waste land parameter unit and the vegetation planning unit. During the verification planting process, the restored vegetation management unit also collects the meteorological data of the planting area through the meteorological sensing unit to ensure the reliability of the data in the subsequent data analysis process;

[0050] Then, the root system monitor is sleeved and wrapped around different varieties of vegetation. The positioning signal ring 1 is fixed on the main trunk of the vegetation near the root ball through a locking hoop. Then, the growth monitoring sleeve 3 and the root protection strips 41 wrap the root ball of the vegetation, and the root guiding ring 4 is sleeved at the lower end of the root ball. Then, according to the planting requirements of the vegetation, the vegetation with the root system monitor is planted at the set position in the monitoring area. During the growth process of the vegetation root system, due to the wrapping effect of the growth monitoring sleeve 3 and the root protection strips 41 on the root system, the vegetation root system will not grow upwards, but is guided downwards, assisting the rooting depth of the vegetation root system. Then, during the downward growth process of the vegetation root system, it will drive the companion root ring 2 to move downward, thereby pulling the growth monitoring sleeve 3 to produce an elongation deformation. Since the root system also grows longitudinally during growth, under the squeezing pressure of the soil, the pressure in the growth monitoring sleeve 3 continuously increases with the growth of the root system. The pressure sensor in the growth monitoring sleeve 3 transmits the data it senses to the girth data module and the depth data module. The girth data module and the depth data module analyze the pressure data, and then transmit the data to the root system monitoring and processing module, enabling it to conduct an overall analysis of the root system data. Then, the analyzed data is transmitted to the vegetation restoration management unit. The vegetation restoration management unit analyzes the growth data of the vegetation root system, and then transmits the analysis results to the data output unit, enabling the data output unit to display the data through the restoration management platform. If it is analyzed and judged that the vegetation grows poorly or the root system stops growing, the data is also transmitted to the vegetation abnormality warning unit at the same time, enabling the vegetation abnormality warning unit to give an abnormality prompt through the restoration management platform. And during the growth process of the vegetation, the vegetation restoration management unit also controls the action of the vegetation maintenance unit according to the meteorological data and the nature of the vegetation planted by the vegetation planning unit, so that the irrigation system irrigates and maintains the vegetation regularly;

[0051] After obtaining the ecological restoration data by forming a vegetation planting network in the ecological restoration test area, the ecological restoration personnel adjusted the applicability of the previous vegetation construction plan according to the growth data of the roots of different plant varieties. Then, they carried out vegetation planting on the mining waste land according to the adjusted data. Still, they divided the monitoring area according to the vegetation planting network formed by different variety planting areas. Then, root monitors were selected for the vegetation planted in the monitoring area. While improving the survival rate to a certain extent, it was also possible to achieve the overall monitoring of the ecological restoration status of the entire mining waste land, facilitating the adjustment of the growth and management of the vegetation by technology. After the vegetation system planned the ecological restoration according to the data of the mining waste land, it was possible to conduct regional monitoring on the roots of the planted vegetation, effectively judge the rationality of the ecological restoration plan according to the growth status of the vegetation roots, and also adjust the maintenance process of the ecological restoration in a timely manner according to the growth data of the vegetation roots, providing reliable reference data in the subsequent continuous ecological restoration construction process, having biological representativeness that conforms to the mining waste land, and also promoting and assisting the growth of the vegetation roots through the settings of the root-associated ring 2 and the growth monitoring sleeve 3, effectively improving the rooting strength of the vegetation and the stability of the vegetation growth on the mining waste land, thereby ensuring the rationality and controllability of the vegetation system, assisting the ecological restoration personnel to promote the mining waste land to achieve the expected ecological restoration goal and shortening the ecological restoration cycle.

[0052] Example 2:

[0053] The present invention provides a stable vegetation system for ecological restoration of mining waste land. Among them, the same or corresponding components as in Example 1 adopt the corresponding reference numerals in Example 1. For the sake of simplicity, only the differences from Example 1 will be described below. The difference between this Example 2 and Example 1 is that: Please refer to Figures 1-12 , a plurality of uniformly distributed induction grooves 42 are provided at the outer end of the root protection strip 41, a flipping group 6 is embedded in the induction groove 42, a torsion bar 52 is rotatably connected in the flipping group 6, an isolation piece 5 is fixedly connected to the upper end of the torsion bar 52. The settings of the flipping group 6 and the isolation piece 5 can, after the root-leading ring 4 and the root protection strip 41 complete the downward guidance of the vegetation roots, conduct outward expansion guidance on the vegetation roots, thereby ensuring the prosperity of the plant roots, ensuring the stability of the vegetation rooting, improving the growth efficiency and wind and sand resistance of the vegetation, and thus achieving the purpose of reducing soil and water loss on the mining waste land.

[0054] Please refer to Figures 1-10, the flipping group 6 includes a liquid-absorbing expansion block embedded in the induction groove 42 and a protective shell fixed to the outer end of the liquid-absorbing expansion block. The liquid-absorbing expansion block is made of expanding rubber, and when installing the liquid-absorbing expansion block, its expansion direction is set to the vertical direction. The torsion bar 52 passes through the protective shell and is rotationally matched with the protective shell. The liquid-absorbing expansion block is located at an eccentric position below the torsion bar 52. The eccentric distance from the center of the torsion bar 52 to the outer end face of the liquid-absorbing expansion block is set as e. The specific value of e here is three-fifths to one-half times the radius of the torsion bar 52, and the liquid-absorbing expansion block is located inside the torsion bar 52, so as to realize the outward turning of the torsion bar 52. After the liquid-absorbing expansion block absorbs liquid, it generates an expansion effect, which can lift and rotate the torsion bar 52 and limit its position, and then realizes the flipping of the torsion bar 52 driving the isolation piece 5, effectively increasing the synergistic effect of the growth monitoring sleeve 3 and the isolation piece 5, and promoting the growth state of the vegetation roots at each stage.

[0055] Please refer to Figures 6-10 , a drainage hole communicating with the induction groove 42 is opened on the root protection strip 41. A plurality of moisture-absorbing plug strips 31 corresponding to the root protection strips 41 are fixedly connected to the inner upper wall of the growth monitoring sleeve 3. A plurality of blocking holes 21 communicating with the drainage holes are opened on the root companion ring 2. The lower ends of the moisture-absorbing plug strips 31 extend to the outside of the growth monitoring sleeve 3 and extend into the blocking holes 21. The growth monitoring sleeve 3 is filled with a drainage liquid, and the drainage liquid here is water. During the growth of the growth monitoring sleeve 3 along with the vegetation roots, since the moisture-absorbing plug strips 31 gradually separate from the blocking holes 21, the drainage liquid inside them will continuously flow into the drainage holes, and then the liquid-absorbing expansion block generates liquid absorption and expansion, which can promote the growth of the vegetation roots, making the isolation piece 5 and the growth monitoring sleeve 3 have a synchronous effect, and reducing the trigger energy consumption, improving the environmental adaptability of the root monitoring device and the adaptability of accompanying growth.

[0056] Please refer to Figures 1-3 , trigger connection pieces are respectively fixedly connected to the upper and lower inner walls of the protective shell, and the positions of the trigger connection pieces correspond to the liquid-absorbing expansion block. The input end of the root monitoring processing module is also connected with a root leading state induction module. The input ends of the depth data module and the root leading state induction module are both connected to the trigger connection piece. The setting of the trigger connection piece fully realizes the full data monitoring of the root growth state by the root monitoring processing module, provides sufficient reference data for the regulation of the vegetation restoration management unit, effectively assists the vegetation restoration management unit to select the vegetation varieties for ecological restoration, and according to the different growth data of the roots of different vegetation varieties, plant them in different required mining waste areas, so as to ensure the reliability of ecological restoration.

[0057] Please refer to Figure 4 , Figure 5 and Figures 8-12, a plurality of root protection packages 51 are fixedly connected to the inner end of the isolation sheet 5. The root protection packages 51 are filled with nutrient solution. A plurality of permeation micropores are formed in the root protection packages 51. The root protection packages 51 can protect the roots of the vegetation in the initial stage of vegetation planting, promote its survival and the growth efficiency of the roots, thereby reducing the cost loss of ecological restoration.

[0058] Please refer to Figures 1-12 , during the process of the growth monitoring sleeve 3 and the root guiding ring 4 following the growth of the vegetation roots, as the growth monitoring sleeve 3 is continuously stretched, the moisture absorption plug strip 31 inside it gradually disengages from the plugging hole 21. After it releases the seal of the plugging hole 21, the drainage liquid in the growth monitoring sleeve 3 enters the drainage hole through the plugging hole 21 and then wets the liquid absorption expansion block, causing the liquid absorption expansion block to continuously absorb water and swell. Then, it exerts a pushing effect on the torsion strip 52, causing the torsion strip 52 to drive the isolation sheet 5 to turn outwards, increasing the gap between the root protection branches 41, enabling the vegetation roots to grow longitudinally, expanding the growth range of the vegetation roots, thereby ensuring its grasping force on the soil and water and the stability of the soil and water. During the continuous expansion of the liquid absorption expansion block, after it expands to contact the inner wall of the protective shell, it abuts against the trigger connection piece, causing the trigger connection piece to be powered on and send a connection signal to the depth data module and the root guiding state induction module. After receiving the data, the root system monitoring and processing module analyzes the growth state of the vegetation roots, and then transmits the analysis data to the restored vegetation management unit. The restored vegetation management unit can timely obtain the data of the vegetation growth, which is convenient for adjusting and controlling the ecological restoration plan.

[0059] The above is only the best implementation mode adopted by the present application in combination with the current actual needs, but the protection scope of the present application is not limited thereto.
