This invention relates to a method for simulating and predicting the spread of *Carex chinensis* mound communities in marsh wetlands. The invention belongs to the field of marsh wetland plant community spread simulation technology, specifically a method for simulating and predicting the spread of *Carex chinensis* mound communities. This invention addresses the problem of not being able to simulate and predict the spread paths and rates of *Carex chinensis* mound communities in marsh wetlands using existing ecological and environmental data. The method involves: acquiring and interpreting remote sensing images; acquiring community characteristic data and ecological and environmental data; processing the acquired remote sensing images and ecological and environmental data to form a database; creating an MCE suitability atlas; simulating the spread of *Carex chinensis* mound communities; verifying the accuracy of the simulation results; and then making predictions. This invention can accurately predict the spread paths and rates of *Carex chinensis* mound communities in marsh wetlands and can be applied to wetland restoration and management.

The utility model discloses an ecological circulating system based on fly ash resource utilization has solved the technical problem of low resource utilization rate. The device includes soil conditioner preparation device, facility agriculture device, anaerobic fermentation device, separation device, purification device, sustainable aviation fuel production device etc. The anaerobic fermentation device carries out fermentation treatment to the crop leftover material or waste of facility agriculture device, to obtain marsh gas, marsh liquid and marsh residue. The separation device separates the marsh liquid and the marsh residue. The marsh residue and the marsh liquid are used for facility agriculture production. The purification device purifies and separates the marsh gas to obtain biological natural gas and green carbon dioxide. The green carbon dioxide can be used for increasing the yield of facility agriculture. It can also be combined with green hydrogen to produce sustainable aviation fuel. The utility model can realize the reasonable integration and utilization of resources, construct a relatively complete ecological circulating system and industrial chain, and improve the resource utilization efficiency.

This application provides a method, apparatus, and equipment for predicting the impact of marsh vegetation change on land surface temperature, belonging to the field of ecological remote sensing and climate effect assessment technology. Based on long-term series leaf area index, land surface temperature, digital elevation model, and marsh wetland distribution data, it first determines the vegetation pixel distribution as the study area within the unchanged marsh wetland distribution range; it then constructs annual and multi-year average growing season datasets using the maximum value synthesis and arithmetic mean methods; within the grid cells, pixels are divided into high and low value groups based on the multi-year average growing season leaf area index, and the difference between the multi-year average growing season leaf area index and the average land surface temperature of all pixels in the high and low value groups is calculated to quantify the degree of land surface temperature change caused by marsh wetland vegetation cover change; finally, by combining the vegetation change trend at the pixel scale, it achieves accurate prediction of the future impact on land surface temperature.

The application relates to a method for improving the survival rate of bighead carp in salt-alkaline water breeding, and belongs to the technical field of fish breeding. The purpose of the application is to solve the problem that the fish species cultivated in fresh water ponds in the process of bighead carp breeding in medium-high salt-alkaline water in the northeast region have a severe stress reaction when being directly put into the medium-high salt-alkaline water in spring and autumn, and the individuals often die when the stress exceeds the bearing range of the fish body, resulting in low survival rate of the put fish species and poor economic benefits of the breeding. The application uses target salt-alkaline lakes, marshes and the like to prepare low-alkaline pond water with a concentration of 1 / 3-1 / 2 of the maximum alkalinity value of the bighead carp fish species in salt-alkaline water breeding, and the fish body is adaptively domesticated to enhance the stress resistance of the fish body and reduce the stress reaction of the fish species cultivated in fresh water ponds when being directly put into the medium-high salt-alkaline water. The application can obtain a method for improving the survival rate of bighead carp in salt-alkaline water breeding.
