Description
Technical Field
The utility model relates to a portable style square frame.
background
The aquatic plants are classified into phytoplankton, submerged plants, emergent aquatic plants and the like, and classified into lower aquatic vascular bundle plants and higher aquatic vascular bundle plants, which are commonly called algae and aquatic weeds. The sloping bank, near bank, shallow water, bay, beach and other slow flow places of rivers and lakes (river and lake for short) generally have a great deal of aquatic plant growth distribution. The aquatic plant is an important component in the water ecological system, is one of main providers of primary productivity, is an enrichment body of N, P, C in water, plays an important role in ecological system balance and ecological environment quality safety, is an important component of biosphere, is related to food supply of human beings, is an environmental element of habitat on which fishes and birds live, is a food base source of various aquatic and terrestrial animals, and is a main attachment substrate of a viscous egg-producing fish spawning site. Benthos live in the bottom of water or the bottom material, and the activity is slower, or inactive, can indirectly gather in aquatic plant appearance, can increase water community composition and correlation data information, obtains more research sample data.
the shallow water areas where large algae (spirogyra, stonewort and the like) and aquatic plants (submerged plants and emergent plants) (hereinafter collectively referred to as aquatic plants) are densely distributed can be called as grass shoals, generally are silt substrates, the water depth is about 2m at most, the substrate landform is relatively flat, but as the water depth is large, the aquatic plants are various in types and forms, mostly live in a fixed residence, have clustering property, large local biomass and density, the communities are relatively stable, roots are generally pricked into the substrate of a water body, roots take roots in water, most of the roots take a growth period in one year, and the roots grow to blossom and fruit and the like from seedlings. In fishery resource and ecological environment investigation, indicators such as the type, biomass, density, community, distribution, and the like of aquatic plants are predetermined investigation items and are also one of water area ecological indicator species. The aquatic plants are sensitive to the environment and have fragility, and the local or regional area is easy to die and disappear wholly, but in the flowing area, due to the wide distribution or germplasm mobility of the migration of water flow, fishes and birds, the aquatic plants have proper environmental conditions and can regenerate and colonize and develop. The aquatic weed research needs to observe various aquatic weed morphological characteristics in a specific living space above and below the water surface, the sample acquisition target has visibility and availability, and the fixed position can be acquired at one time. The sample survey is a necessary survey means, can quickly and accurately quantitatively collect samples, and provides reliable basis for scientific research. However, the water surface or the water cannot be scribed vertically or horizontally, the wire is difficult to be drawn for forming, and the sample frame is difficult to place at the luxuriant aquatic weeds or uneven substrates, so that the research sample of the aquatic weeds is difficult to be acquired in a positioning and quantitative manner, and the sampling and quantitative research is difficult to be carried out. In addition, the sample box is mainly used in research and study processes of agriculture, forestry, scientific research, teaching and the like, and a sample party is often required to be arranged in the field for research, so that factors such as the number, frequency, growth characteristics and the like of biological distribution are observed. At present, tools such as tape rulers and measuring ropes are generally adopted for setting a sample square, and a sample frame is manufactured by pulling and positioning on site, so that the boundary line and the direction are not easy to accurately control. In addition, the square sample frame is made of a thickened aluminum plate by hand, and is unfolded to form the square sample frame when in use, the frame is not fixed, and the wind resistance and the water flow resistance are weak. The method is suitable for positioning and collecting samples on land, and the sample frame is deformed and irregular due to the arrangement and the measurement in water, so that inaccurate survey data are easily caused. Therefore, in the research of aquatic organism resources, water body primary productivity, water body purification, fish spawning sites, water area ecological restoration and other works, a special sample frame suitable for quantitative aquatic organism collection is needed, and the problem is not solved at present.
