Description

Survey dipperstick of plant diversity

Technical Field

The invention relates to an auxiliary measuring tool for investigating plant diversity, in particular to a measuring scale for investigating plant diversity.

Background

In the aspect of ecology, landscape pattern and the like, the diversity of plants in a certain place needs to be determined. The most commonly used method in determining plant diversity is the same method: a plurality of sampling points are selected in a measuring area, a plurality of sampling parties are selected from each sampling point, and then plant data statistics is carried out on each sampling party. Randomly selecting a plurality of samples in the living environment of the investigated plant population, counting the number, density, coverage and height of individuals in each sample, and obtaining the data such as population density, relative coverage, relative height, frequency, important value and the like of each sample. The size of the sample is generally 1 meter by 1 meter or 5 meters by 5 meters square, and four measuring staff are required to stand at four right-angled points of the square to divide the measuring range of the sample by taking a tape measure. Because each sample has more data to be measured, four investigators are occupied for more time, and the selection range of the sample is changed by the posture adjustment of the surveyors sometimes to influence the measurement effect. To investigate accuracy, the number of samples is thousands to hundreds. Every appearance needs five surveyors, and one measures the reading, and four-digit long-time pole of standing is lifted and is enclosed the rope, can not move or influence data, consumes a large amount of manpower resources, and the pole is easily moved inconvenient carrying, and the string is twined easily, and the measurement process still needs to use a plurality of chi to measure.

Detailed Description

As shown in fig. 1 to 5, a measuring ruler for investigating the diversity of plants comprises a fixing device and a flexible rule; the number of the fixing devices is four; the number of the flexible rulers is four; the four fixing devices are completely the same, and the four flexible rulers are completely the same. The four flexible rulers, namely a flexible ruler I2, a flexible ruler II 4, a flexible ruler III 6 and a flexible ruler IV 8 are respectively connected with four fixing devices, namely a fixing device I1, a fixing device II 3, a fixing device III 5 and a fixing device IV 7, to form a square; the fixing device comprises two mutually perpendicular ruler guide arms 9, and ruler guide grooves 10 are formed in the ruler guide arms 9. The two mutually perpendicular guide arms 9 intersect to form an L-shape, and the insertion ground end 12 is mounted on the guide arm 9 below the plane of the two mutually perpendicular guide arms 9. The ground insertion end 12 is below the intersection of two mutually perpendicular guide arms 9. A fixed flexible rule end 11 is arranged above the intersection of the two mutually perpendicular guide rule arms 9. Two ends of the flexible rule are provided with flexible rule hanging rings 14, and the flexible rule hanging rings 14 are sleeved on the fixed flexible rule end 11. The flexible rule hanging ring 14 is circular or square. The distal ends of the two tape guide arms 9 have a correcting direction surface 13. The scale surface 15 of the tape is facing upwards.

The using process of the invention is as follows: according to the installation shown in the figure 1, the ground inserting end 12 of the fixing device I1 is inserted into the soil for fixing, one flexible rule hanging ring 14 of the flexible rule I2 is hung on the fixed flexible rule end 11 of the fixing device I1, the flexible rule I2 is straightened along the correcting direction surface 13 of the fixing device I1, the fixed flexible rule end 11 of the fixing device II 3 is inserted into the other flexible rule hanging ring 14 of the flexible rule I2, and the ground inserting end 12 of the fixing device II 3 is inserted into the soil for fixing under the condition that the flexible rule I2 is straightened and the direction is unchanged. And hanging one flexible rule hanging ring 14 of the second flexible rule 4 on the fixed flexible rule end 11 of the second fixing device 3, pressing the flexible rule hanging ring 14 of the second flexible rule 4 on the flexible rule hanging ring 14 of the first flexible rule 2, straightening the second flexible rule 4 along the correction direction surface 13 of the second fixing device 3, finding a ground fixed point of the third fixing device 5, fixing the third fixing device 5, and hanging the other flexible rule hanging ring 14 of the second flexible rule 4 on the fixed flexible rule end 11 of the third fixing device 5.
