Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration, and in particular to a swamp seed plant community restoration device based on micro-topography transformation. Background Art

[0002] Swamps are one of the most important ecosystems in nature, playing an important role in maintaining biodiversity and providing ecosystem services. Swamp plants, as one of the key components, are the basis for the stability of the structure, function and process of the swamp ecosystem. However, the increasingly degraded status of swamps has greatly reduced the service function of the ecosystem, making the restoration of swamp plants an important task in the current scientific research field. In the past, the restoration of swamp plants was mainly carried out by means of vegetation transplantation and seed sowing. However, when promoting this restoration measure, human, material and financial resources have become the biggest limitations, and the restoration results are often limited and random. This is because seeds require certain conditions in the early stage of germination and the growth of transplanted seedlings, and these conditions often show huge differences due to environmental heterogeneity, species differences and climate variability. Therefore, in-depth analysis of the impact of the key life history stages of seed plants on the stability of the entire community structure is the key to achieving the optimal consumption-benefit relationship. Given that the randomness and uncertainty of seed plant seed dispersal are affected by topographical features, surface geomorphic structural units, namely micro-topography transformation, are effective ways to increase the seed bank and improve the fate of seed germination. It is necessary to develop technical theoretical methods and devices based on micro-topography creation. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a swamp seed plant community restoration device based on micro-topography transformation.

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 7As shown, a swamp seed plant community restoration device based on micro-topography transformation includes a drum 1 and a driving device 5, wherein rollers 11 are provided at the axis of both ends of the drum 1, and the driving device 5 is connected to the rollers 11 through a connecting rod 12, and the driving device 5 pushes or pulls the drum 1; a plurality of raised pressing blocks 2 are detachably installed on the surface of the drum 1, and the pressing blocks 2 are various configurations (can be any shape) for constructing micro-topography, and a probe 3 for detecting soil hardness is also installed on the surface of the drum 1, and the function of the probe 3 for detecting soil hardness is to adjust the actual height between the drum 1 and the ground according to the hardness of the soil, so that the degree of compaction of the ground can be achieved, and the purpose of adjusting the depth of the pit groove can be achieved. Therefore, based on scientific research, the best survival micro-topography conditions for the survival of certain salt marsh plant seeds or seedlings are obtained to set the size of the pit shape. The probe 3 adjusts the height between the drum 1 and the ground according to the hardness of the soil, and adjusts the depth and shape of the cavity. Among them, the pressing block 2 and the drum 1 are connected by snap fit or screws. The driving device 5 adopts a rail-type (or chain-type) conveyor belt device to prevent the drum 1 from sinking into the muddy tidal flat, and the conveyor belt can realize automatic rolling and rolling distance design.

[0018] Preferably, the driving device 5 is also equipped with a lifting platform device 4 for adjusting the height position of the drum 1. Figure 5-Figure 7 As shown, the driving device 5 can adopt a rail-type transmission device, a chain-type transmission device or a conveyor belt transmission device to avoid the roller sinking due to tidal mud, and the conveyor belt can realize automatic rolling and rolling distance design.

[0019] In the process of creating micro-topography, since the number of seed banks and seed germination conditions depend on the stability of the size of micro-topography, and the stability of micro-topography depends on the hardness of the soil, it is necessary to obtain the relationship between the number of seed banks (S) and the number of seed germination (M) and the micro-topography structure (such as depth and opening size) based on research in advance, and at the same time, it is necessary to determine under what soil texture conditions such depth and opening size can remain stable. Finally, based on the optimal number of seed banks and the number of seed germination, the micro-topography creation structural components are screened. The components are selected, and the depth and caliber of the micro-topography are created according to the soil texture conditions, that is, the soil hardness. The depth and caliber are obtained according to the degree of rolling of the soil by the rolling wheel. In this process, a probe 3 for detecting the hardness of the soil is installed on the roller 1. After the probe 3 measures the hardness of the soil, the contact surface height between the roller 1 and the soil is automatically adjusted. If the soil is very soft, then only light rolling will appear to form a deeper micro-topography. If the soil is very hard, then heavy rolling is required. The data measured by the probe 3 should be comprehensively considered according to the research area, vegetation type, and terrain design size. Before starting the repair, the device must be parameterized, the micro-topography structure to be used must be given, and then the functional relationship must be set based on the functional relationship between soil hardness and terrain depth or opening area. After the setting, during the operation of the entire device, the probe will adjust the height of the roller 1 above the ground surface according to the hardness value of the soil to achieve regulation of the terrain compaction process. During use, different functional relationships will be set for different micro-topography structure selections, and this functional relationship needs to be measured on-site in advance to provide a standard curve. This standard curve is the standard function curve for the operation of the device. Figure 3 As shown, one of the configurations of the pressing block 2 is shown, that is, the side view of the pressing block 2 structure installed on the drum, and the shape pressed out on the surface is a graphic groove. Figure 4 As shown, the drum 1 is in a load-bearing state and is used to roll on the bottom surface. The shapes of the pressing blocks 2 installed on the drum 1 can be various, and their shapes depend on the microenvironmental conditions (dry and wet conditions, temperature, etc.) for the growth of seed vegetation.

[0020] The weight of the rolling is automatically adjusted by the lifting and supporting platform device 4, so that the height of the terrain component (block 2) on the outer surface of the drum and the ground changes. The depth of the constructed terrain meets the optimal depth. Since the ecological restoration process is often large-scale, it cannot be achieved in the form of manpower, and automation is required. This requires a moving platform capable of lifting the bracket and the drum 1. The driving device adopts a rail-type transmission device or a chain-type transmission device or a conveyor belt transmission device. The driving device is used to carry the drum 1, and then the restoration practice activities based on the creation of micro-topography are carried out in the restoration area. After the probe 3 measures the hardness of the soil, the height of the lifting and supporting platform device 4 bracket is automatically adjusted, so that the height of the terrain component on the outer surface of the drum 1 and the ground changes, so that the depth of the constructed terrain meets the optimal depth.

[0021] The above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. That is, all simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the invention description are still within the scope of the patent of the present invention, for example: by changing the probe, that is, the probe type, detecting the redox potential, conductivity, etc., because these are the conditions that affect seed germination, and these indicators are directly related to the microtopography.
