Abstract
The utility model relates to a novel collecting quantitative frame for macrobenthos samples in an intertidal zone. The novel collecting quantitative frame for macrobenthos samples in the intertidal zone comprises a frame body and a handle, wherein the frame body is in the form of a cuboid with an upper opening; the bottom surface of the frame body is square; the height of the frame body is bigger than the side length of the bottom square; and a handle is arranged on two opposite sides of the upper opening of the frame body, respectively. The bottom square of the frame body is 25 cm in side length and 30cm in height. The novel collecting quantitative frame for macrobenthos samples in the intertidal zone can be used for enabling the sediment collecting depth to be 30cm on the basis of enabling the surface area to 0.0625 m<2>, and therefore, the novel collecting quantitative frame is in particular suitable for collecting the macrobenthos in the intertidal zone with soft mud substrate. Moreover, in a hard mud sandy sediment environment, when the quantitative frame cannot be easily inserted to the sediment, the quantitative frame can be pressed into the sediment by increasing physical strength through pedals. Meanwhile, after the sampling is completed, the novel collecting quantitative frame can be used for conveniently removing the sediment from the quantitative frame.
Description
Technical field
The utility model belongs to large-scale benthonic invertebrates sample sampling instrument technical field, particularly relates to the quantitative frame of a kind of novel intertidal zone large-scale zoobenthos sample collection.
Background technology
The clear and definite sampling area of large-scale zoobenthos quantitative sampling inevitable requirement just can be converted into population density (individual/square metre) and biomass (gram/square metre) like this, thereby carry out further time or spatial diversity analysis when later data is handled.When the large-scale zoobenthos sample of subtidal zone was gathered, " marine monitoring standard " regulation sampling area was 0.1m
2Or 0.025m
2,, use sampling area to be 0.1m usually both at home and abroad at this requirement
2Or 0.025m
2Grab type adopt or the bottom sampler (box bottom sampler, static(al) bottom sampler etc.) of other types.Gather for the large-scale zoobenthos sample in intertidal zone at present, " marine monitoring standard " also has clearly regulation, and the surface area of the large-scale zoobenthos quantitative collection in code requirement intertidal zone is 0.0625m
2, the degree of depth is 30cm, filter out comprising large-scale zoobenthos.Particularly consider in the actual samples process 0.0625m
2Be a very little area in fact, therefore,, then may in data handling procedure, produce very big error as can not be accurately quantitative.We in the sampling process of intertidal zone, use surface area to be 0.0625m in reality usually
2Small-sized quantitative frame (Fig. 2), this quantitative frame is convenient to a certain extent, standard the end sample collection of dwelling, but have following 2 obvious defectives simultaneously: (1) degree of depth can't accurately guarantee, usually can only judge by sampling person's subjective experience, though most large-scale zoobenthos are distributed in sedimental top layer, it is less to comprise large-scale zoobenthos in the sediments below the 20cm, but sampling depth lack of standardization causes sampling error certainly to a certain extent.Particularly along with the end dwell deepening continuously of ecological study and standard, will inevitably be more and more higher for the requirement of sampling.(2) in the sampling of the intertidal zone of ooze substrate, this quantitative frame is difficult to effectively use because ooze caves in easily, excavate certain depth after, on every side sediments can be constantly from around cave in, can't carry out quantitatively, cause tangible sampling error.
Summary of the invention
Technical problem to be solved in the utility model provides the quantitative frame of a kind of novel intertidal zone large-scale zoobenthos sample collection, designs a kind of novelty, science, practicality, to can be applicable to the intertidal zone quantitative frame of large-scale zoobenthos sample collection significant.
The technical scheme that its technical problem that solves the utility model adopts is: provide the large-scale zoobenthos sample collection of a kind of novel intertidal zone quantitative frame, comprise framework and handle, described framework is the cuboid of a top opening, the bottom surface of described framework is a square, described framework tall and big be the foursquare length of side in the bottom surface, on two opposite side of described framework top opening a handle is housed respectively.
25 centimetres of the bottom surface square length of sides of described framework, high 30 centimetres.
This patent mainly designs and comprises 2 points:
One, the degree of depth of the framework that will use at present is increased to 30cm by 10cm;
Two, in framework mouth both sides 1 lever is installed respectively.
Beneficial effect
The utility model design can guarantee that surface area is 0.0625m
2The basis on, guarantee gathering sediment depth is 30cm, this design is particularly suitable for the large-scale zoobenthos in intertidal zone of ooze substrate and gathers.And, in the sandy sediments environment of stiff mud, can not easily quantitative frame be inserted sedimental the time, by the foot-operated strength that increases, quantitative frame by in sediments, simultaneously, after finishing sampling work, is conveniently removed quantitative frame from sediments.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the prior art constructions schematic diagram.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the quantitative frame of a kind of novel intertidal zone large-scale zoobenthos sample collection, comprise framework 1 and handle 2, described framework 1 is the cuboid of a top opening, the bottom surface of described framework 1 is a square, described framework 1 tall and big be the foursquare length of side in the bottom surface, on two opposite side of described framework 1 top opening a handle 2 is housed respectively.
25 centimetres of the bottom surface square length of sides of described framework 1, high 30 centimetres.
This patent mainly designs and comprises 2 points:
The degree of depth of the framework 1 that one, will use at present is increased to 30cm by 10cm;
Two, in 1 mouthful of both sides of framework 1 lever is installed respectively.
At first quantitative frame is inserted in the sediments during sampling, then sediments in the quantitative frame is Removed All bushing screen, flushing then, the sediments residue that can not wash brings to the laboratory, dyes, rough segmentation, picks out large-scale zoobenthos.As run into ooze matter sediments, can with hand quantitative frame be pressed onto in the sediments very like a cork.As run into the sandy sediments of stiff mud, and then can apply bigger strength by trampling lever, quantitative frame is depressed in the sediments.After sediments Removes All, can quantitative frame be removed from sediments by handle, finish the once flushing task.
