Description

Technical Field

[0001] The utility model relates to the technical field of investigation statistics, and more specifically, to an ecological field investigation sample frame. Background Art

[0002] Ecological field survey refers to the activities of ecologists or ecological researchers to conduct field observations, measurements and data collection in natural environments to understand the structure, function, dynamic changes and interactions of biological communities and ecosystems. Ecological field surveys usually require the collection of a large number of biological and environmental samples, the recording and observation of various biological phenomena, and the collection and organization of a large amount of data. Ecological field surveys are one of the important means of ecological research and are also the foundation of ecological research.

[0003] In ecological field surveys, in order to ensure that the collected data is representative and comparable, a sample plot is usually used as the basic unit of sampling. A sample plot is a rectangular area, usually a square or a rectangle, and its size can be determined according to the purpose of the research. In an ecosystem, multiple sample plots can be randomly selected, and each sample plot can be sampled and observed to obtain various data and information about the ecosystem.

[0004] Among them, it was found through searching that the utility model patent with patent application number CN202222374858.7 discloses an ecological field survey sample frame, which relates to the field of survey statistics technology, including several side panels, sleeves are symmetrically installed on the side panels, guide grooves are provided on the sleeves, a fixing nail is slidably connected in the sleeves, a push rod is connected to the upper end of the fixing nail, the push rod is slidably connected in the guide groove, a spring is sleeved on the fixing nail, the two ends of the spring are respectively connected to the fixing nail and the sleeve, and a hook ring is provided at the upper end of the sleeve;

[0005] When the structure is in use, a side panel on one side is placed on the ground, and then the push rod on the side panel is pushed downward along the guide groove, and the arc-shaped hook angle limit push rod is moved upward, so that the fixing nail extends from the sleeve and embeds into the ground to fix the side panel, and then the side panels are operated in sequence to form a sample square frame, so as to avoid the sample square frame slipping and deformation caused by the uneven ground when setting the sample square frame in the field, thereby improving the accuracy of collecting and estimating the total number of plants in the area. However, the structure is not easy to store and transport when in use, and the sampling storage capacity of the device itself is low, and it is not easy to classify different biological and environmental samples, and it is not convenient enough when in use.
