Description

Technical Field

[0001] This invention relates to the field of building materials technology, and in particular to a pre-laid ring-shaped replanting method suitable for deep-water lakes and reservoirs. Background Technology

[0002] Submerged plant cultivation is a crucial step in aquatic ecological restoration. According to relevant research, the planting method is closely related to the survival rate of planted vegetation. Southwest China has a unique geographical environment, with many lakes and reservoirs forming deep "V" shapes, averaging over 3.5 meters in depth, and shallow water areas accounting for less than 30%. This makes submerged plant cultivation inefficient, underwater forest construction difficult, and prevents the use of conventional methods for submerged plant cultivation, resulting in insufficient planting area and density.

[0003] Currently, for deep lakes and reservoirs, the common practice is to replenish water to overflow the planting area before planting submerged plants, alternating between replenishment and planting. However, due to rising water levels and the circular increase in water area, the increase in planting area varies per unit of time, leading to significant dynamic changes in labor and submerged plant availability. Labor and planting efficiency cannot be dynamically matched with the amount of water replenishment, greatly reducing the efficiency of submerged plant planting, failing to guarantee the planting area and density, diminishing ecological restoration capacity, increasing the cost of subsequent replanting, and jeopardizing the safety of underwater planting personnel. Therefore, a solution is urgently needed.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a pre-laying ring-shaped retreat planting method suitable for deep water lakes and reservoirs. This planting method calculates the difference in area between the water area to be planted on the same day and the next day due to water replenishment, and adopts an advanced planting method to solve the problem of mismatch between labor allocation per unit time and planting area during the planting and water replenishment process in deep water lakes.

[0006] To achieve the aforementioned objective, the technical solution of the present invention is implemented as follows: a pre-laid circular replanting method suitable for deep-water lakes and reservoirs, the circular replanting method comprising:

[0007] S1. Construct a planting mathematical model, which is used to calculate the daily planting area of ​​the water area to be planted.

[0008] S2. Based on the planting mathematical model, calculate the areas that need to be planted ahead of schedule due to rising water levels after daily water replenishment.

[0009] S3. Arrange for workers to plant underwater vegetation in the waters that need to be planted in advance;

[0010] S5. In areas where advanced planting has been completed, workers will be arranged to cover the areas with sunshade nets, depending on the weather and temperature.

[0011] S6. Once the water level rises to submerge the pre-planted areas, arrange for workers to remove the sunshade nets.

[0012] Preferably, the planting mathematical model sets the water area to be planted as a circle and uses it as a prerequisite for calculation.

[0013] Preferably, the main calculation parameters of the planting mathematical model include determining the slope K of the slope of the planting water area, determining the calculation period, the amount of water replenishment within the calculation period, and the water area of ​​the water area to be planted.

[0014] Preferably, the calculation period is from 12:00 noon on the same day to 6:00 a.m. on the next day.

[0015] Preferably, the water replenishment amount within the calculation period is the daily water replenishment amount Q of the water area to be planted, determined at 12:00 every day.

[0016] Preferably, the water area of ​​the water area to be planted within the calculation period includes the water area S1 of the water area to be planted determined at 12:00 every day, and the water area S1 and the daily water replenishment Q are substituted into the planting mathematical model; the planting mathematical model calculates the height H of the water level to be planted at 6:00 on the second day, the width L of the water area extending outward in the horizontal direction, and the water area S2 of the water area to be planted at 6:00 on the second day, and arranges personnel to plant ahead of time based on the area difference between the water area S2 and the water area S1.

[0017] Preferably, the calculation cycle also includes the period from 6 to 12 on the second day, determining the amount of water replenishment from 6 to 12, and substituting it with the water area S2 of the water area to be planted at 6 into the planting mathematical model, and arranging the number of planting workers in the morning according to the calculation results of the planting mathematical model; the workers arrive at the site and then begin the circular backward and forward planting of the planting area of ​​the first night.

[0018] Preferably, the calculation logic of the planting mathematical model is as follows: determine the water replenishment amount Q within the calculation period, the water area S1 at 12 noon on the current day, and determine the slope K of the planting water area slope; and assume that the horizontal outward extension width of the water area from 12 noon on the current day to 6 am on the next day is L, and the water level rise height is H, then:

[0019] ①: H = kL;

[0020] ②: The radius of the water area to be planted is set to a circle on that day.

[0027] ⑧: Expand the area according to the water area △ S calculates the number of planting workers needed that afternoon and allocates personnel accordingly.

[0028] The beneficial effects of this invention are reflected in:

[0029] (1) This invention utilizes the principle of rising water level and expanding planting area to construct a planting mathematical model. The planting mathematical model calculates the labor demand per unit time in different time periods, thereby solving the problem that labor and planting efficiency cannot achieve dynamic balance with water replenishment and improving the planting efficiency of submerged plants.

[0030] (2) This invention adopts the method of pre-planting submerged plants, that is, planting in advance. This method of planting in advance based on the amount of water replenishment can not only reduce the safety hazards of operators and ensure the root depth of submerged plants, but also improve the adhesion stability of the submerged plant base and reduce the cost of replanting later while solving the safety problem of underwater planting.

[0031] (3) By adopting a ring-shaped receding planting method, this invention can not only improve the uniformity and aesthetics of submerged plant planting, but also solve the problem that the planting density and uniformity do not meet the requirements due to the turbidity of the water in underwater planting. This improves the efficiency of planting operations, avoids the need for replanting later, and reduces planting costs. Detailed Implementation

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] This invention provides a pre-laid circular replanting method suitable for deep-water lakes and reservoirs, comprising:

[0035] S1. Construct a mathematical model for planting. On-site staff will use the mathematical model to calculate the daily planting area and the number of people responsible for planting in the waters to be planted.

[0036] S2. Based on the planting mathematical model, calculate the areas that need to be planted ahead of schedule due to rising water levels after daily water replenishment.

[0037] S3. Arrange workers in advance to plant underwater plants in the waters where planting is required.

[0038] S5. In areas where advanced planting has been completed, workers should be arranged to cover the planted plants with sunshade nets according to the weather and temperature to prevent them from dehydrating and dying.

[0039] S6. Once the water level rises to submerge the areas planted ahead of schedule, arrange for workers to remove the sunshade nets.

[0040] The prerequisite for using the planting mathematical model is to designate the water area to be planted as a circle. This facilitates calculations and reduces the difficulty of data collection. During actual planting operations, the number of personnel can be adjusted based on the calculation results to ensure the effectiveness of the planting mathematical model.

[0041] The main computational parameters for the planting mathematical model include: determining the slope K of the slope of the planting water area, determining the calculation period, the amount of water replenishment during the calculation period, and the water area of ​​the water area to be planted.

[0042] Considering that the water replenishment work of the reservoir is carried out from the afternoon to the morning of the next day, the calculation period of the mathematical model is set to 12 noon on the same day to 6 am the next day.

[0043] In practice, at 12:00 noon each day, staff determine the water replenishment amount for the calculation period as Q; simultaneously, they determine the water area S1 of the area to be planted within the calculation period. The water area S1 and the daily water replenishment amount Q are then input into the planting mathematical model to calculate the water level height H reached at 6:00 AM the following day. Combined with the slope K of the planting area's side slope, the horizontal width L of the area to be planted and the water area S2 are calculated. The difference in water area between the two days, S2 - S1, is then derived from the calculation.

[0044] This method allows us to predict the area that needs to be planted in advance, i.e., the area difference. Based on the planting area of ​​each worker per unit of time, it is easier to arrange for people to plant between 12 noon on the same day and 6 am on the next day.

[0045] In addition, if the water area to be planted is to be replenished between 6:00 AM and 12:00 PM the next day, the amount of water replenished and the area of ​​the water area to be planted at 6:00 AM can be used as a basis to input the planting mathematical model. The number of planting workers in the morning can be arranged according to the calculation results of the planting mathematical model. After the workers arrive at the site, they will start planting in a circular backward movement in the planting area of ​​the first night.

[0046] Example 2,

[0047] The calculation method for the planting mathematical model is as follows:

[0048] Calculate the water replenishment volume Q during the calculation period, and the water area S1 at 12:00 noon. Assume the horizontal outward extension width of the water area from 12:00 noon to 6:00 the next day is L, and the water level rise is H, then:

[0049] ①: H = kL;

[0050] ②: The radius of the water area to be planted is set to a circle on the same day.

[0051] ③:S2=π(r+L) 2 ;

[0052] ④:

[0053] ⑤: Substituting ①, ②, and ③ into ④ and simplifying, we can solve using the formula for a cubic equation.

[0054]

[0055] ⑥: Substitute the results from ② and ⑤ into ③ to obtain S2;

[0056] ⑦: The water area will expand from 12 noon to 6 am the next day. △ S = S2 - S1;

[0057] ⑧: Expand the area according to the water area △ S calculates the number of planting workers needed that afternoon and allocates personnel accordingly.

[0058] The above solution not only allows for the rational allocation of personnel to plant in advance in the designated planting areas, thus eliminating the dangers of underwater operations, but also improves the survival rate of underwater vegetation, thereby reducing construction difficulty and enhancing planting results.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
