Description

Technical Field

[0001] The present application relates to the field of plant adaptability evaluation, and in particular to a method and system for determining a plant adaptability index value. Background Art

[0002] The construction of photovoltaic power stations has developed rapidly. The desert area (including deserts) is 2.61 million km2, accounting for 27.2% of the country's land area, of which the desert area is about 700,000 km2 and the Gobi area is more than 500,000 km2, providing a vast space for the development of the photovoltaic industry. More than 60% of the potential for solar energy resource development is concentrated in the western desert areas. These areas not only have good solar energy resources, but also do not occupy precious arable land resources, and the land use cost is low, making them ideal places for large-scale construction of ground-based photovoltaics.

[0003] The desert region has a dry climate, scarce precipitation, and frequent wind and sand activities, which poses a huge challenge to the safe and stable operation of photovoltaic power stations. Studies have shown that wind and sand activities cause erosion under photovoltaic panels, forming wind erosion pits (grooves) with the lower edge of the photovoltaic panels as the axis, and the base columns are exposed, which will threaten the stability of the fixed structure of photovoltaic modules. At the same time, after the forward movement of sand dunes and the obstruction of wind and sand flow, sand burial and sand accumulation will form on the leeward side of the photovoltaic panels. Strong winds and sandstorms directly blow over photovoltaic arrays, causing damage to photovoltaic modules. Therefore, planting plants in the above-mentioned areas is the main means of preventing sand and consolidating soil. How to accurately select plants with better adaptability has become a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present application provides a method and system for determining a plant adaptability index value, so as to at least solve the technical problem of low accuracy in determining the plant adaptability index.

[0019] Furthermore, the adaptability index values ​​of various types of plants are determined according to the membership values ​​of various indicators of various types of plants, including:

[0020] Determine the average values ​​of the membership functions of various types of plants according to the membership values ​​of various indicators of various types of plants;

[0021] The average values ​​of the membership functions of the various types of plants are used as the adaptability index values ​​of the various types of plants.

[0042] Embodiment 1

[0043] Figure 1 A flow chart of a method for determining a plant adaptability index value according to an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes:

[0044] Step 1: Obtain the index values ​​of various types of plants in the area and determine the relationship between each index value and ecological adaptability.

[0045] In the embodiment of the present disclosure, the various indicator values ​​include:

[0046] Survival rate index value, relative growth rate index value, plant height index value, root length index value, photosynthetic parameter index value, leaf relative water content index value and leaf water potential index value;

[0047] The photosynthetic parameter index values ​​include: photosynthetic rate index value and stomatal conductance index value.

[0048] It should be noted that the relationship between the various index values ​​and ecological adaptability includes:

[0049] The index value is positively correlated with ecological adaptability, and the index value is negatively correlated with ecological adaptability.

[0050] The survival rate index value, relative growth rate index value, plant height index value, root length index value, photosynthetic parameter index value, leaf relative water content index value and leaf water potential index value in this embodiment are all positively correlated with ecological adaptability.

[0051] It should be noted that the process of obtaining each indicator value includes:

[0052] 1. Survival rate index value:

[0053] At a fixed time point, record the number of plants planted, and after a period of time (such as a few weeks or months), record the number of surviving plants again. Use the following formula to calculate the survival rate: Survival rate = (number of surviving plants / total number of plants planted) × 100%;

[0054] 2. Relative growth rate index value:

[0055] During a period of time, the initial biomass of the plant (e.g., the weight or volume of the plant) is recorded. At the end of the same period of time, the biomass of the plant is recorded again, and the relative growth rate is calculated using the following formula: relative growth rate index value = (ln (biomass final value) - ln (biomass initial value)) / time;

[0056] 3. Plant height index value:

[0057] Use a measuring tape to measure the distance from the soil surface to the highest point of the plant (usually the tip of the plant or the tops of the leaves).

[0058] 4. Root length index value:

[0059] Remove the plant from the soil and gently clean the roots to ensure they are intact. Using a root length gauge or ruler, measure the total length of the roots along the axis of the root system.

[0060] 5. Photosynthetic parameter index values:

[0061] Use a photosynthesis measurement system (such as Li-Cor6400) to measure parameters such as photosynthetic rate and stomatal conductance, and record them.

[0062] 6. Leaf relative water content index value:

[0063] Collect a certain number of leaf samples and record their freshness quality;

[0064] Immerse the leaf sample completely in deionized water to saturate it, shake the water off the leaf surface, and record the saturated mass of the leaf;

[0065] The leaf samples were placed in a desiccator until their weight stabilized and the dry mass of the leaves was recorded.

[0066] The relative leaf water content was calculated using the following formula:

[0067] Leaf relative water content index value = ((fresh mass - dry mass) / (saturated mass - dry mass)) × 100%;

[0068] 7. Leaf water potential index value:

[0069] Determine the leaf water potential index value using a pressure chamber or water potential meter.

[0070] Step 2: Determine the membership value of each indicator of each type of plant based on the relationship between each indicator value and ecological adaptability and each indicator value of each type of plant.

[0071] In the embodiment of the present disclosure, step 2 specifically includes:

[0072] Based on the values ​​of various indicators of various types of plants, the maximum and minimum values ​​of various indicators are screened out;

[0073] When the index value is positively correlated with ecological adaptability, the membership value of each index of each type of plant is determined using the formula U(Xij)=(Xij-Xjmin) / (Xjmax-Xjmin);

[0074] When the index value is negatively correlated with ecological adaptability, the formula U(Xij)=1-(Xij-Xjmin) / (Xjmax-Xjmin) is used to determine the membership value of each index of each type of plant;

[0075] Among them, U(Xij) is the membership value of the jth indicator of the i-th plant, Xij is the j-th indicator value of the i-th plant, Xjmin is the minimum value of the j-th indicator, and Xjmax is the maximum value of the j-th indicator.

[0076] Step 3: Determine the adaptability index value of each type of plant according to the membership value of each index of each type of plant.

[0077] In the embodiment of the present disclosure, step 3 specifically includes:

[0078] Determine the average values ​​of the membership functions of various types of plants according to the membership values ​​of various indicators of various types of plants;

[0079] The average values ​​of the membership functions of the various types of plants are used as the adaptability index values ​​of the various types of plants.

[0080] It should be noted that the larger the average value, the better the adaptability of the species.

[0081] In summary, the method for determining the adaptability index value of a plant proposed in this embodiment can accurately determine the adaptability index of various types of plants, providing a basis for the subsequent construction of a photovoltaic power station.
