Technical Field
The utility model relates to a runoff pond especially relates to a runoff pond for karst stony desertification area, belongs to field test and detects technical field.
Background
The karst rock desertification area has serious water and soil loss, and due to the special overground and underground binary structure, underground leakage and earth surface loss coexist, which brings great difficulty to the research and control of the water and soil loss in the area. By researching the water and soil loss and nutrient loss mechanism in the karst region, the water and soil nutrient loss rule is mastered, and corresponding leakage resistance control treatment is adopted according to the rule. The method has important practical significance for maintaining soil fertility in the karst rocky desertification area, promoting vegetation recovery and preventing water and soil loss; meanwhile, the ecological, economic and social development is promoted, the water and soil leakage and nutrient loss mechanism is researched, the vegetation recovery is combined with leakage resistance control and stony desertification control, and the stony desertification is controlled through vegetation recovery in the ecological industry, so that the ecological benefit is achieved, and the economic benefit and the social benefit are unified.
The runoff pond is a common and traditional water and soil loss monitoring method in karst rock desertification areas, and the method can only monitor the soil and water loss on the earth surface and the nutrient loss caused by the soil and water loss on the earth surface. In karst regions, due to the special overground and underground binary structure, surface water and soil loss and underground water and soil loss also exist. And the water and soil loss is difficult to monitor, and a large amount of nutrients can be lost, so that the growth of plants is influenced.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: the utility model provides a runoff pond for karst stony desertification area, the utility model discloses a 10 runoff pond the inside under different planting modes is with same arrangement method installation soil moisture sensor, through the change condition of moisture along with the rainfall under the different modes of contrast, the different planting mode underground part's of contrastive analysis moisture migration condition to and the earth's surface water and soil loss condition, reveal different planting mode water and soil nutrient leakage and loss situation, and then provide the scientific foundation for stony desertification comprehensive control, solve the leakage mechanism problem of karst stony desertification area nutrient.
The technical scheme of the utility model is that: the utility model provides a runoff pond for karst stony desertification area, it includes pond wall frame and soil moisture sensor, the concrete structure of pond wall frame for the square frame shape, is filled with the soil horizon in the centre of pond wall frame, plant different vegetation on the soil horizon, bury a plurality of soil moisture sensors in the centre of soil horizon.
The specification of the pool wall frame is 1200cm long, 300cm wide and 50cm deep.
The soil moisture sensors are uniformly distributed in the pool wall frame in three rows from left to right, and two rows are arranged, wherein one or two soil moisture sensors which are arranged at an overlapped interval are arranged in each row in the soil depth direction.
The soil moisture sensor is a 5TE soil moisture sensor of the American Decagon company, and the soil moisture sensor is connected with a data collector outside the soil layer through a data line.
The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, this technical scheme is through the dynamic change of the moisture of soil and conductivity in the different runoff ponds of the same monitoring method contrastive analysis, and the water-salt migration condition in the soil is monitored to system, science, accuracy. The method for installing the runoff pool instrument can systematically reflect the water-salt migration condition of the whole runoff pool. Meanwhile, the method can achieve long-time, objective and continuous dynamic monitoring, can reflect the water-salt migration condition in the runoff pond more truly, and avoids time-consuming and labor-consuming manual sampling analysis. Greatly improves the scientific research efficiency and time, and has a large amount of real and reliable data.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Example 1: as shown in the attached figures 1-4, the runoff pond for the karst stony desertification area comprises a pond wall frame 1 and soil moisture sensors 3, wherein the pond wall frame 1 is of a square concrete structure, a soil layer 2 is filled in the middle of the pond wall frame 1, different vegetation is planted on the soil layer 2, and the soil moisture sensors 3 are embedded in the middle of the soil layer 2.
Further, the cell wall frame 1 has a length of 1200cm, a width of 300cm and a depth of 50 cm.
Further, the soil moisture sensors 3 are uniformly distributed in the pool wall frame 1 in three rows from the left, the middle and the right, and two rows are arranged in each row, wherein one or two soil moisture sensors 3 which are arranged at an overlapped interval are arranged in the soil depth direction in each row.
