This invention discloses an ecological scheduling method and its application based on fish reproductive needs, belonging to the field of environmental protection technology in water conservancy and hydropower engineering. This invention specifically addresses the challenge of protecting fish that lay adhesive eggs. By establishing a population reproductive characteristic adaptation domain model (Ω(pi)), it quantifies for the first time the dynamic response relationship between water level fluctuations (proximal factor) and water temperature and flow velocity (terminal factor), breaking through the limitations of traditional ecological scheduling that only focuses on a single hydrological indicator. It achieves multi-objective collaborative optimization, balancing engineering needs such as flood control, power generation, and water supply with ecological protection through a dynamic adjustment model of ΔH(t). Through proximal factor monitoring and terminal factor feedback, it corrects the water level adjustment ΔH(t) in real time, improving the response speed compared to traditional methods. Furthermore, by dividing the control period according to the key processes of the fish life history, the water level fluctuation limit during the spawning period is more precise, providing an innovative technical method for ecological scheduling in water conservancy projects.

The invention discloses an SNP (Single Nucleotide Polymorphism) marker related to the body size and temperature adaptability of worker bees of apis cerana and application of the SNP marker. According to the invention, 25 key SNP sites and 10 associated genes for regulating and controlling the body type and temperature adaptation of the apis cerana are screened by a selection signal analysis method. Research finds that in the second intron region (6452066th site of the chromosome 7 of the bees) of the Foxo gene, the mutation type is T / C, and the mutation type is closely related to the body size and temperature adaptability of the Chinese bees. Through verification, in Hainan apis cerana and Aba apis cerana with extremely different body sizes and living environment temperatures, mutation position genotypes are different, TT is a large-body cold-resistant dominant genotype, and CC / TC is a small-body heat-resistant dominant genotype; a gene expression quantity detection result shows that the expression quantity of the Foxo gene is in negative correlation with a large body type and cold resistance and is in positive correlation with a small body type and heat resistance. The method can be used for genetic improvement of bee body shape characters and has breeding application value.
