Technical Field

[0001] The utility model relates to the field of plant diversity investigation tools, in particular to an adjustable portable sample square frame. Background Art

[0002] In outdoor surveys of biological (plant) diversity, when conducting sample data statistics within the sample site, some existing sample frames have irregular boundaries and are highly mobile. Commonly used sample frames are fixed sample frames, or are directly surrounded by wire, which take up a large space and cannot be adjusted in size. They have poor adaptability and are not easy to carry when encountering special areas.
