Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

In the description of the present invention, it should be understood that the terms "central", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., used herein are used in the orientation or positional relationship indicated in the drawings, which are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted" and "connected" are to be interpreted broadly, e.g., as being either fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 4, an embodiment of the present invention provides a bird food source retention facility in a river beach, including a closure pile wall 1, where both sides of the closure pile wall 1 are provided with a rough stone layer 2, the closure pile wall 1 extends from a river bank 3 to the interior of a river in an arc shape, and an upper end of the closure pile wall 1 is higher than an upper surface of the rough stone layer 2.

Based on above-mentioned scheme, when the ebb, the food source is detained by enclosing pile wall 1 and rubble layer 2, and birds can stand and seek food on enclosing pile wall 1, can provide more food sources for birds, increases birds dwell time and seeks the food total amount, and rubble layer 2 provides the space for the benthonic animal, has promoted the diversity of the benthonic animal that stops in river beach and birds.

Specifically, in the present embodiment, as shown in fig. 1, the source detention facility is similar to a fan shape, as shown in fig. 2, the rubble layer 2 on one side close to the river bank 3 is longer than the rubble layer 2 on the other side, the water level is limited by controlling the height difference between the rubble layer 2 and the upper end of the enclosing pile wall 1, so that birds can find food conveniently, and the water level is generally 0.3-1.5 m.

In this embodiment, as shown in fig. 1, the enclosure pile wall 1 is composed of three rows of wooden piles, which can sufficiently block benthonic organisms, but other rows may be provided in other embodiments.

In order to provide adaptive stopping points for birds of different sizes, as shown in fig. 3 and 4, in some embodiments, the upper end surface of the enclosure pile wall 1 is in a shape of high and low undulations from one end of the enclosure pile wall 1 to the other end, that is, the height of the pile is high or low, and the distance between the upper end of the enclosure pile wall 1 and the horizontal plane 5 has various forms, which can be controlled by the pile driving height. Different foraging depths (namely water depths) formed by combining the height fluctuation of the rubble layer 2 meet the feeding requirements of different birds.

Specifically, the foraging depths of different birds can be referred to as follows: aigrette, such as small aigrette, night aigrette, pall, etc., which uses small and medium aquatic animals as food, and the foraging water level is within 0.3 m; wild goose ducks such as spotted-mouth ducks and swan geese, which like wide water surface, mainly feed on aquatic plants, have the foraging water depth of less than 0.3m and the inhabitation water level of less than 1 m; plover curls, such as golden plover, black wing long-foot curls, and the like, feed on benthonic animals, and have a foraging water depth of 0.05m to 0.15 m; Podicedidae, the aquatic animals and plants are taken in water with water depth over 50 cm.

In the present embodiment, as shown in fig. 2, the particle size of the whetstone on the lower portion of the whetstone layer 2 is larger than that on the upper portion of the whetstone layer 2. Specifically, the silt line position 4 in the middle of the rubble layer 2 is used as a boundary, and the particle size of the rubble above the silt line position 4 is smaller than that of the rubble below the silt line position 4. The hair stone gaps provide acupuncture points for benthonic organisms, and the hair stones with different particle sizes generate gaps with different sizes, so that different activity environments are provided for the benthonic organisms.

Further, the particle size of the rubble on the lower part of the rubble layer 2 is 60-80 mm, and the particle size of the rubble on the upper part of the rubble layer 2 is 30-50 mm.

Optionally, the enclosure pile wall 1 can be made of pine piles, bamboo piles or cement piles.

To sum up, the embodiment of the utility model provides a river beach bird food source detention facility, when ebb tide, the food source is detented by the enclosure pile wall 1 and the rubble layer 2, birds can stand on the enclosure pile wall 1 to seek food, more food sources can be provided for the birds, the bird detention time and the total amount of foraging are increased, the rubble layer 2 provides space for benthonic animals, and the diversity of the benthonic animals and the birds staying on the river beach is improved.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
