Description

Technical Field

[0001] The present invention relates to the technical field of ecological restoration, and in particular to a system and method for assessing and restoring biodiversity in arid areas. Background Art

[0002] Arid areas are areas that lack sufficient rainfall and often experience persistent dryness and water shortages for most of the year. Ecosystems in these areas are easily affected, and agricultural production and human life may be seriously affected.

[0003] Currently, restoration work in arid areas is mainly implemented by increasing water supply, including rainwater collection, reservoir construction, and groundwater recharge. At the same time, in order to maintain soil fertility and moisture, measures such as preventing soil erosion, vegetation coverage, and artificial greening are also taken. However, without targeted and effective control measures, these efforts may not be able to completely restore the ecological environment in arid areas, and may even aggravate the problem of soil erosion.

[0075] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0076] like Figure 1 As shown, in some embodiments of the present application, this embodiment provides a biodiversity assessment and restoration system for arid areas, including: a vegetation planting unit, a soil moisture detection module, a temperature detection module, a fertility detection module, an irrigation module, a fertilizer release module, a scoring module and a central control module. The vegetation planting unit is set in a preset restoration area in the arid area, and the vegetation planting unit is planted with a number of vegetations. The vegetation planting unit is used to perform ecological restoration on the preset restoration area. There are several soil moisture detection modules, and the several soil moisture detection modules are respectively set in the preset restoration area. The soil moisture detection module is used to detect the soil moisture of the preset restoration area. The temperature detection module is set in the preset restoration area, and the temperature detection module is used to detect the real-time temperature of the preset restoration area. The fertility detection module is set in the preset restoration area, and the fertility detection module is used to detect the fertility of the preset restoration area, wherein the fertility includes: organic matter content, chemical nutrient content, and pH value. The irrigation module and the fertilizer release module are respectively set in the preset restoration area, and the irrigation module is used to irrigate the several vegetations in the vegetation planting unit, and the fertilizer release module is used to release fertilizer to the several vegetations in the vegetation planting unit. The scoring module is electrically connected to the soil moisture detection module, the temperature detection module and the fertility detection module respectively. The scoring module is used to obtain the soil moisture, real-time temperature and fertility of the preset restoration area, and evaluate the soil drought score according to the preset soil moisture, real-time temperature and fertility of the restoration area. The central control module is electrically connected to the scoring module, the irrigation module and the fertilizer release module respectively. The central control module is used to determine the drought level of the soil according to the soil drought score, and determine the irrigation amount of the vegetation and the release amount of fertilizer according to the soil drought level.

[0077] It can be seen that suitable vegetation is planted in the preset restoration area through the vegetation planting unit to increase soil coverage, reduce water evaporation and soil erosion, and thus improve the soil and water loss in the area. Secondly, the soil moisture detection module, temperature detection module and fertility detection module monitor key indicators such as soil moisture, temperature and fertility in real time, providing a scientific basis for decision makers to adjust irrigation and fertilization strategies and improve the efficiency of ecological restoration. The irrigation module and fertilizer release module provide water and nutrients to vegetation based on monitoring data, promote vegetation growth, and accelerate the recovery of the ecosystem. The scoring module assesses the degree of soil drought based on soil moisture, temperature and fertility, and the central control module determines the amount of irrigation and fertilizer release based on the score to achieve intelligent management and optimal resource utilization.

[0078] It is understandable that through the deployment of vegetation planting units, the system can effectively increase soil coverage, reduce water evaporation and soil erosion, thereby improving the soil and water loss in the region and protecting the stability and sustainability of soil resources. Secondly, the use of soil moisture detection module, temperature detection module and fertility detection module enables the system to monitor key indicators such as soil moisture, temperature and fertility in real time, which provides a scientific basis for decision makers to scientifically and rationally adjust irrigation and fertilization strategies, maximizing the efficiency and effectiveness of ecological restoration. In addition, the precise use of irrigation modules and fertilizer release modules provides vegetation with appropriate amounts of water and nutrients based on real-time monitoring data, promotes the healthy growth of vegetation, and helps accelerate the recovery and stability of the ecosystem. The introduction of the scoring module and the central control module enables the entire system to achieve intelligent management and optimal resource utilization, and intelligently adjusts the amount of irrigation and fertilizer release according to the soil drought score, thereby improving resource utilization efficiency and reducing waste.

[0079] In some embodiments of the present application, when the scoring module evaluates the soil drought score according to the soil moisture, real-time temperature and fertility of the preset restoration area, it includes: the scoring module is also used to obtain the real-time soil moisture of the preset restoration area, and judge whether the preset restoration area is suitable for vegetation planting according to the relationship between the real-time soil moisture and the preset soil moisture: when the real-time soil moisture is higher than or equal to the preset soil moisture, the scoring module judges that the preset restoration area is suitable for vegetation planting. When the real-time soil moisture is lower than the preset soil moisture, the scoring module judges that the preset restoration area is not suitable for vegetation planting, and determines the soil drought score of the preset restoration area according to the relationship between the real-time soil moisture and the preset soil moisture.

[0080] It is understandable that the scoring module first obtains the real-time moisture data of the soil and compares it with the preset soil moisture. If the real-time humidity is higher than or equal to the preset humidity, the scoring module will judge that the area is suitable for vegetation planting, because high humidity may mean that additional water supply is needed to support vegetation growth. On the contrary, if the real-time humidity is lower than the preset humidity, the scoring module judges that the area is not suitable for vegetation planting because the soil moisture cannot meet the needs of the plants. The scoring module determines the soil drought score of the preset restoration area based on the relationship between the real-time soil moisture and the preset humidity. Such a scoring process fully considers the important impact of soil moisture on vegetation growth, thereby providing an important reference basis for better adjustment of ecological restoration strategies and measures.

[0081] In some embodiments of the present application, when the scoring module determines that the preset restoration area is not suitable for vegetation planting and determines the soil drought score of the preset restoration area according to the relationship between the real-time soil moisture and the preset soil moisture, the scoring module includes: the scoring module is also used to obtain the humidity difference L between the real-time soil moisture and the preset soil moisture, and set L=l-l0, l is the real-time soil moisture, and l0 is the preset soil moisture. The scoring module is also used to compare the humidity difference L with the preset humidity difference, and determine the soil drought score of the preset restoration area according to the comparison result: wherein the scoring module is also used to pre-set a first preset humidity difference L1 and a second preset humidity difference L2, and L1<L2. When L≤L1, the scoring module determines that the soil drought score of the preset restoration area is M3. When L1<L≤L2, the scoring module determines that the soil drought score of the preset restoration area is M2. When L>L2, the scoring module determines that the soil drought score of the preset restoration area is M1. Wherein, M1<M2<M3.

[0082] It is understandable that the scoring module obtains the humidity difference between the real-time soil humidity and the preset soil humidity, and then the scoring module compares the humidity difference L with the preset humidity difference range to determine the soil drought score of the preset restoration area. Within the preset humidity difference range, the scoring module determines different drought score levels according to different thresholds. For example, when the humidity difference L is within a smaller range (L≤L1), the scoring module determines that the soil drought score of the preset restoration area is M3, indicating severe drought; when the humidity difference L is within a relatively medium range (L1<L≤L2), the scoring module determines that the soil drought score is M2, indicating moderate drought; when the humidity difference L exceeds a larger range (L>L2), the scoring module determines that the soil drought score is M3, indicating mild drought. In this way, the scoring module can accurately assess the degree of soil drought according to the changes between the real-time humidity and the preset humidity, providing a more accurate reference for ecological restoration.

[0083] In some embodiments of the present application, when the scoring module determines that the soil drought score of the preset restoration area is Mi, i=1,2,3,...,i, it includes: the scoring module is also used to obtain the real-time soil organic matter content, the real-time soil chemical nutrient content and the real-time soil pH value of the preset restoration area. The scoring module is also used to obtain the organic matter content difference Q between the real-time soil organic matter content and the preset organic matter content, Q=q-q1, q is the real-time soil organic matter content, and q1 is the preset organic matter content. The scoring module is also used to obtain the nutrient content difference W between the real-time soil chemical nutrient content and the preset chemical nutrient content, W=w-w0, w is the real-time soil chemical nutrient content, and w0 is the preset chemical nutrient content. The scoring module is also used to obtain the pH difference R between the real-time soil pH value and the preset pH value, R=r-r0, r is the real-time soil pH value, and r0 is the preset pH value. The scoring module is also used to obtain the fertility score of the preset restoration area based on the organic matter content difference Q, the nutrient content difference W and the pH difference R, and based on the formula, the formula is as follows:

[0084] K=(Q*z1)+(W*z2)+(R*z3).

[0085] Among them, K is the fertility score of the preset restoration area, z1, z2 and z3 are weight coefficients, and the sum of z1, z2 and z3 is 1.

[0086] In some embodiments of the present application, the scoring module is further used to adjust the soil drought score Mi of the preset restoration area according to the relationship between the fertility score K and the preset fertility score, including: wherein the scoring module is also used to preset a first preset fertility score K1 and a second preset fertility score K2, and the scoring module is also used to preset a first preset adjustment coefficient N1, a second preset adjustment coefficient N2 and a third preset adjustment coefficient N3, and K1<K2, N1<N2<N3<1; when K≤K1, the scoring module selects the first preset adjustment coefficient N1 to adjust the soil drought score Mi of the preset restoration area. When K1<K≤K2, the scoring module selects the second preset adjustment coefficient N2 to adjust the soil drought score Mi of the preset restoration area. When K>K2, the scoring module selects the third preset adjustment coefficient N3 to adjust the soil drought score Mi of the preset restoration area. When the scoring module selects the i-th preset adjustment coefficient Ni to adjust the soil drought score Mi of the preset restoration area, i=1,2,3, and determines that the adjusted soil drought score of the preset restoration area is P, and sets P=M i*N i.

[0087] It can be understood that the scoring module obtains important indicators such as the real-time organic matter content, chemical nutrient content and pH value of the soil, and calculates the difference between the preset values. Subsequently, based on these differences, the scoring module uses the preset weight coefficient and formula to calculate the fertility score K of the preset restoration area. Next, the scoring module adjusts the soil drought score Mi of the preset restoration area based on the relationship between the fertility score K and the preset fertility score. Specifically, the scoring module compares the fertility score K with the preset fertility score according to different preset thresholds and adjustment coefficients to determine the degree of adjustment of the drought score. When the fertility score K is within different threshold ranges, the corresponding adjustment coefficient is selected to adjust the drought score. In this way, the scoring module can dynamically adjust the drought score according to the soil fertility status, so that the drought score more accurately reflects the actual degree of drought in the soil.

[0088] In some embodiments of the present application, when the scoring module selects the i-th preset adjustment coefficient Ni to adjust the soil drought score Mi of the preset repair area, and determines that the adjusted soil drought score of the preset repair area is P, it includes: the scoring module is also used to obtain the real-time temperature of the preset repair area, and determine the water evaporation degree of the preset repair area according to the relationship between the real-time temperature and the preset temperature: when the real-time temperature is lower than the preset temperature, the scoring module determines that the water evaporation degree of the preset repair area is low. When the real-time temperature is higher than or equal to the preset temperature, the scoring module determines that the water evaporation degree of the preset repair area is high, and according to the relationship between the real-time temperature and the preset temperature, the adjusted soil drought score P of the preset repair area is corrected.

[0089] In some embodiments of the present application, when the scoring module determines that the water evaporation degree of the preset repair area is high, and according to the relationship between the real-time temperature and the preset temperature, the soil drought score P of the preset repair area is corrected and adjusted, including: the scoring module is also used to obtain the temperature difference J between the real-time temperature and the preset temperature, J=j-j0, wherein j is the real-time temperature and j0 is the preset temperature. The scoring module is also used to compare the temperature difference J with the preset temperature difference, and select the corresponding correction coefficient according to the comparison result to correct the soil drought score P of the preset repair area after adjustment: wherein the scoring module is also used to pre-set the first preset temperature difference J1 and the second preset temperature difference J2, and the scoring module is also used to pre-set the first preset correction coefficient B1, the second preset correction coefficient B2 and the third preset correction coefficient B3, and J1<J2, B1<B2<B3<0.8. When J≤J1, the scoring module selects the first preset correction coefficient B1 to correct the soil drought score P of the preset repair area after adjustment. When J1<J≤J2, the scoring module selects the second preset correction coefficient B2 to correct the preset soil drought score P of the repair area after adjustment. When J>J2, the scoring module selects the third preset correction coefficient B3 to correct the preset soil drought score P of the repair area after adjustment. When the scoring module selects the i-th preset correction coefficient Bi to correct the preset soil drought score P of the repair area after adjustment, i=1,2,3, and determines that the corrected preset soil drought score of the repair area is P1, and sets P1=P*Bi.

[0090] It can be understood that the scoring module obtains the real-time temperature of the preset repair area, and judges the degree of water evaporation based on the relationship between the real-time temperature and the preset temperature. If the real-time temperature is lower than the preset temperature, the water evaporation degree is judged to be low; if the real-time temperature is higher than or equal to the preset temperature, the water evaporation degree is judged to be high. Then, the scoring module compares the difference between the real-time temperature and the preset temperature, that is, the temperature difference J, with the preset temperature difference range to determine the correction coefficient. According to different temperature difference ranges, the corresponding correction coefficient is selected to correct the soil drought score of the adjusted preset repair area. For example, when the temperature difference J is within a small range (J≤J1), the first preset correction coefficient B1 is selected for correction; when the temperature difference J is within a medium range (J1<J≤J2), the second preset correction coefficient B2 is selected for correction; when the temperature difference J exceeds a larger range (J>J2), the third preset correction coefficient B3 is selected for correction. In this way, the scoring module can dynamically adjust the soil drought score according to the change of real-time temperature, so that the score more accurately reflects the actual drought situation of the soil.

[0091] In some embodiments of the present application, when the central control module is used to determine the drought level of the soil according to the soil drought score, it includes: the central control module is also used to pre-set a first preset drought score A1 and a second preset drought score A2, and A1<A2. The central control module is also used to determine the drought level of the soil according to the relationship between the revised preset soil drought score P1 of the restoration area and each preset drought score, wherein: when P1≤A1, the central control module determines that the drought level of the soil is low. When A1<P1≤A2, the central control module determines that the drought level of the soil is medium: when P1>A2, the central control module determines that the drought level of the soil is high: wherein low<medium<high.

[0092] In some embodiments of the present application, when the central control module determines the amount of watering for vegetation and the amount of fertilizer released according to the drought level of the soil, it includes: the central control module is also used to pre-set the first preset watering amount, the second preset watering amount and the third preset watering amount, the central control module is also used to pre-set the first preset fertilizer release amount, the second preset fertilizer release amount and the third preset fertilizer release amount, and the first preset watering amount < the second preset watering amount < the third preset watering amount, the first preset fertilizer release amount < the second preset fertilizer release amount < the third preset fertilizer release amount. When the drought level of the soil is low, the central control module determines the first preset watering amount as the amount of watering for vegetation, and determines the first preset fertilizer release amount as the amount of fertilizer released for vegetation. When the drought level of the soil is medium, the central control module determines the second preset watering amount as the amount of watering for vegetation, and determines the second preset fertilizer release amount as the amount of fertilizer released for vegetation. When the drought level of the soil is high, the central control module determines the third preset irrigation amount as the irrigation amount for the vegetation, and determines the third preset fertilizer release amount as the fertilizer release amount for the vegetation.

[0093] It can be understood that the central control module pre-sets thresholds for different drought levels, namely the first preset drought score A1 and the second preset drought score A2, to ensure the classification standard of drought levels. Subsequently, according to the relationship between the revised preset soil drought score P1 of the restoration area and the preset drought score threshold, the central control module determines the drought level of the soil, which is divided into low, medium and high levels. Then, the central control module formulates corresponding irrigation and fertilization strategies based on the irrigation amount and fertilizer release amount preset for different drought levels. For example, when the drought level of the soil is low, the first preset irrigation amount and the first preset fertilizer release amount are determined; when the drought level of the soil is medium, the second preset irrigation amount and the second preset fertilizer release amount are determined; when the drought level of the soil is high, the third preset irrigation amount and the third preset fertilizer release amount are determined. In this way, the central control module can dynamically adjust the water and nutrient supply of the vegetation according to the degree of drought of the soil to improve the efficiency and effectiveness of ecological restoration.

[0094] In the above embodiment, the use of vegetation planting units can not only improve soil coverage, reduce water evaporation and soil erosion, but more importantly, it can also improve soil structure, increase soil organic matter content, and improve soil water and fertilizer retention capacity, thereby providing a more favorable environment for plant growth. Secondly, the setting of soil moisture detection module, temperature detection module and fertility detection module can monitor and grasp the moisture, temperature and fertility of soil in real time. The accurate monitoring of these key indicators provides a scientific basis for decision makers, and can adjust the irrigation and fertilization strategies according to actual conditions, maximize the use of limited water resources and fertilizer resources, and improve the efficiency and effectiveness of ecological restoration. In addition, the use of irrigation modules and fertilizer release modules enables the precise control of water and nutrition supply according to real-time monitoring data to ensure that the nutrients and water required for vegetation growth are sufficient. The introduction of scoring modules and central control modules enables the entire system to achieve intelligent management and optimal resource utilization, automatically adjust the irrigation amount and fertilizer release amount according to actual conditions, maximize resource utilization efficiency, and achieve sustainable development of ecological restoration.
