Description

Water level control methods for waterbird habitats

The present invention relates to wetland management, in particular to a water level control method for waterbird habitats.

Wetlands are transitional zones between terrestrial ecosystems and aquatic ecosystems. As a unique natural habitat, wetlands are extremely rich in biodiversity resources and provide good habitats and habitats for many wild animals, especially waterbirds. Foraging environment. In addition, wetlands also have the function of regulating ambient temperature and can absorb carbon dioxide. According to research, they can absorb approximately 2.87 grams of carbon per square meter.

In addition, there are many species of waterbirds, and each waterbird has its own preferred water depth. For example, the snipe family, the plovers and the teal use areas with water depths of 12 cm, 7 cm and 10 cm respectively; the antheridae require two types of habitats, namely resting on bare land and shoals within 12 cm of water depth, and 12 ~30 cm of deep water for feeding; Great Egrets and Little Egrets of the family Egretidae use areas ranging from bare land to water depths of 40 cm on average, but Great Egrets have high demand for surrounding vegetation, and Little Egrets use a higher proportion of bare land and shoals; Black-faced spoonbills prefer areas 18 to 35 centimeters deep and use exposed areas to rest.

In addition, when a wetland has a water level, the water depth distribution of the wetland can be obtained from the difference between the water level and the absolute terrain elevation distribution of the wetland. For example, assuming that the water level is -12 cm and the water level at the lowest point of the absolute terrain elevation distribution is -52 cm, then the water depth of the wetland at the lowest point is -12-(-52)=40 cm. Please refer to Figure 1 for its schematic diagram.

However, wetlands are visited by different waterbirds in different seasons. Therefore, a fixed water level cannot meet the habitat needs of waterbirds in different seasons. That is, some waterbirds may not be able to find habitats with suitable water depth in wetlands. In addition, if waterbirds suitable for a specific water depth of the wetland do not visit, the corresponding area of the specific water depth will become an ineffective habitat.

In order to solve the above problems, a novel water level control method for waterbird habitats is urgently needed in this field.

One object of the present invention is to disclose a water level control method in a waterbird habitat, which can dynamically adjust the water level of a wetland to maximize the number of species of waterbirds inhabiting the wetland.

Another object of the present invention is to disclose a water level control method for waterbird habitats, which can dynamically adjust the water level of a wetland according to different types of visiting waterbirds in different seasons to prevent local areas of the wetland from becoming ineffective habitats.

Another object of the present invention is to disclose a water level control method in a waterbird habitat, which can use green electricity to drive a gate to adjust the water level of a wetland while reducing carbon emissions.

In order to achieve the aforementioned purpose, a water level control method for waterbird habitats is proposed, which is executed by a control unit. The method includes the following steps: Read the absolute terrain elevation distribution of a wetland from a database; Read from the database the data on the species of waterbirds that inhabit the wetland within a predetermined period and the statistical data on the water depth distribution of a group of waterbird habitats corresponding to the data on the species of waterbirds that inhabit; Read the median of the statistical data with the largest water depth among the water depth distribution statistics of the waterbird habitat, and determine a target water level based on the sum of the median and the lowest terrain elevation of the absolute terrain elevation distribution; and A gate control device is driven to deliver water to the wetland or to withdraw water from the wetland so that the water level of the wetland reaches the target water level.

In a possible embodiment, the predetermined period is one month in the future or one quarter in the future.
