Description

Technical Field

[0001] This utility model belongs to the field of agricultural ecological environment management technology, and more specifically, it relates to a farmland-type ecological buffer zone structure. Background Technology

[0002] River and lake ecological buffer zones serve as natural barriers between rivers and lakes, acting as a connection and transitional zone between river / lake ecosystems and terrestrial ecosystems. Spatially, they encompass not only the area between high and low water levels in rivers and lakes but also the region extending a certain distance from the high water level into the land. With urban development and farmland expansion, natural riverbank vegetation buffer zones are gradually being destroyed. River and lake shores, as a crucial component of these ecological buffer zones, are bearing the brunt of this land-to-water expansion, being progressively eroded and squeezed by cities and farmland.

[0003] Based on the above, the inventors have discovered the following problems: existing natural riverbanks are being directly cultivated into farmland and vegetable gardens, resulting in river and lake basins being adjacent to farmland, and pollutants being directly dumped or entering the river directly with rainfall runoff; farmland runoff carries large amounts of nutrients such as nitrogen and phosphorus, causing agricultural non-point source pollution; riverbanks are being hardened or channelized, and natural shorelines are gradually disappearing, leading to a gradual reduction in river ecosystems and threatening the ecological security of river and lake waters.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a farmland-type ecological buffer zone structure in order to achieve a more practical value. Utility Model Content

[0005] The purpose and effect of this utility model's farmland-type ecological buffer zone structure are achieved through the following specific technical means:

[0006] A farmland-type ecological buffer zone structure includes a first land buffer zone, an ecological storage pond, a second land buffer zone, and a sunken green space. The first land buffer zone, the ecological storage pond, the second land buffer zone, and the sunken green space are distributed sequentially from the farmland side to the riverbank side. The first land buffer zone and the second land buffer zone are planted with trees, shrubs, and herbaceous ground cover. The ecological storage pond is provided with an impermeable layer, an adsorption layer, and a plant layer from bottom to top. The sunken green space is covered with a buffer base and planted with herbaceous plants and shrubs.

[0007] Furthermore, the impermeable layer is covered with impermeable geotextile.

[0008] Furthermore, the adsorption layer is covered with ceramsite and gravel.

[0009] Furthermore, the plant layer is planted with emergent and submerged plants.

[0010] Furthermore, the buffer base is provided with several buffer blocks.

[0011] Furthermore, the buffer base is provided with a number of permeable holes, which are connected to the bottom of the recessed green space.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By sequentially setting up a land buffer zone I, an ecological storage pond, a land buffer zone II, and a sunken green space from the farmland side to the riverbank side, non-point source pollution from farmland is effectively intercepted, pollutants entering the river are reduced, the river's self-purification capacity is strengthened, the development of aquatic plant and animal diversity is promoted, and the ecological benefits are well realized.

[0014] By planting trees, shrubs, and ground cover, trees and shrubs can protect embankments, reduce riverbank erosion, intercept sediment, absorb and retain nutrients, and increase wildlife habitats. Ground cover can block particulate matter in surface runoff through plant roots, absorb nitrogen and phosphorus, degrade pollutants such as pesticides, and act as a barrier to slow down and accumulate runoff, promoting the infiltration and deposition of pollutants in runoff.

[0015] By planting herbaceous plants and shrubs, pollutants from surface runoff can be blocked from entering the river. At the same time, they can also store rainwater and regulate floods, ensuring that floods enter the river less during the rainy season and reducing sediment from being washed into the river channel, thus providing a regulating barrier for the restoration of the river's aquatic ecosystem.

[0016] The buffer blocks on the buffer base buffer the impact of the water source and intercept the sediment. The water source on the buffer base seeps into the bottom of the sunken green space through the infiltration holes to prevent the surface from being washed away by the water source.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 3 As shown:

[0027] This utility model provides a farmland-type ecological buffer zone structure, including a land buffer zone 1, an ecological storage pond 2, a second land buffer zone 3, and a sunken green space 4. The land buffer zone 1, ecological storage pond 2, second land buffer zone 3, and sunken green space 4 are distributed sequentially from the farmland side to the riverbank side. The land buffer zone 1 and second land buffer zone 3 are planted with trees, shrubs, and ground cover. The trees and shrubs can protect the riverbank, reduce riverbank erosion, intercept sediment, absorb and retain nutrients, and increase wildlife habitat. The ground cover can block particulate matter in surface runoff and absorb pollutants through its root system. Nitrogen and phosphorus, as well as pesticide and other pollutants, act as a barrier to slow down and accumulate runoff, promoting the infiltration and deposition of pollutants in the runoff. The ecological storage pond 2 is equipped with an impermeable layer 8, an adsorption layer 9, and a plant layer 10 from bottom to top. The sunken green space 4 is covered with a buffer base 5 and planted with herbaceous plants and shrubs. The herbaceous plants and shrubs block pollutants brought by surface runoff from entering the river, and at the same time, they can also accumulate rainwater and regulate floods, ensuring that floods enter the river slowly during the rainy season, reducing the amount of sediment washed into the river channel, and providing a regulating barrier for the restoration of the river's aquatic ecosystem.

[0028] The impermeable layer 8 is covered with impermeable geotextile to prevent farmland sewage from seeping or running off.

[0029] The adsorption layer 9 is laid with ceramsite and gravel to adsorb pollutants such as nitrogen, phosphorus and pesticides in wastewater.

[0030] The plant layer 10 is planted with emergent and submerged plants, which effectively transform and retain pollutants through plant absorption and substrate adsorption. At the same time, the farmland runoff flowing into the ecological storage pond 2 can be recycled for irrigation, thereby improving the water resource utilization rate.

[0031] The buffer base 5 is provided with several buffer blocks 6, which intercept mud and sand, buffer water sources, and prevent the surface from being washed away by water sources.

[0032] The buffer base 5 is provided with a number of permeation holes 7, which are connected to the bottom of the sunken green space 4. The use of the permeation holes 7 facilitates the water source on the buffer base 5 to permeate to the bottom of the sunken green space 4.

[0033] The specific usage and function of this embodiment are as follows:

[0034] First, check the integrity of the structure. Use is only permitted after confirmation of its integrity. During use, the structure is arranged sequentially from the farmland side to the riverbank side: Land Buffer Zone 1, Ecological Storage Pond 2, Land Buffer Zone 2, and Sunken Green Space 4. Land Buffer Zones 1 and 2 are planted with trees, shrubs, and ground cover. Trees and shrubs protect the riverbank, reduce riverbank erosion, intercept sediment, absorb and retain nutrients, and increase wildlife habitat. Ground cover, through its root system, blocks particulate matter in surface runoff, absorbs nitrogen and phosphorus, and degrades pollutants such as pesticides, acting as a barrier to slow and accumulate runoff, promoting the infiltration and deposition of pollutants. Ecological Storage Pond 2, from bottom to top, consists of an impermeable layer 8, an adsorption layer 9, and a plant layer 10. The impermeable layer 8 is laid with impermeable geotextile to prevent farmland wastewater infiltration or runoff. The adsorption layer 9 is laid with expanded clay and gravel to adsorb nitrogen, phosphorus, and pesticide pollutants from wastewater. The plant layer 10 is planted with emergent plants and... Submerged plants effectively transform and retain pollutants through plant absorption and substrate adsorption. Simultaneously, farmland runoff flowing into the ecological storage pond 2 can be recycled for irrigation, improving water resource utilization. Herbaceous plants and shrubs planted in the sunken green space 4 block pollutants from surface runoff into the river, while also accumulating rainwater and regulating floods, ensuring slower flooding during the rainy season and reducing sediment runoff into the river channel. This provides a buffer barrier for the restoration of the river's aquatic ecosystem. Buffer blocks 6 on the buffer base 5 buffer the impact of water sources and retain sediment. Water from the buffer base 5 permeates through infiltration holes 7 to the bottom of the sunken green space 4, preventing surface erosion. This effectively intercepts non-point source pollution from farmland, reduces pollutants entering the river, helps strengthen the river's self-purification capacity, promotes aquatic biodiversity, and ensures good ecological benefits. This device has a novel overall design and simple structure, making it worthy of widespread promotion and use.
