With the continuous innovation of science and technology, the mathematical modeling and analysis of bodily injury in the process of exercise have always been a hot and difficult point in the research field of scholars. Although there are many research results on the nonlinear classification of the basketball sports neural network model, usually only one model is used, which has certain defects. The combination forecasting model based on the ARIMA model and neural network based on LSTM can make up for this defect. In the process of the experiment, the most important is the construction of the combination model and the acquisition of volunteer data in the process of the ball game. In this experiment, the ARIMA model is used as the linear part of the data, and LSTM neural network model is used to get the sequence of body injury. The results of the empirical study show that: it is reasonable to divide the injury of thigh and calf in the process of basketball sports, which is very consistent with the force point of the human body in the process of sports. The results of the two models predicting the average degree of bodily injury for many times are about 0.32 and 0.38 respectively, which are far less than 1. The execution time of the program for simultaneous prediction on the computer is about 1 minute, which is extremely effective.

The purpose of this article is to explore the possibility of creating an ecological network that includes core areas, buffer zones, ecological corridors, and restoration areas in the section of the Shamakhi district of the Shahdagh National Park (Azerbaijan). Materials and methods. As materials, we used vector and raster data, as well as literature materials to determine and analyse the elements of an ecological network. Operations were performed by using ArcGIS 10.8 and ERDAS Imagine software. During the field research, observations were made in order to match the elements of the ecological network with the cameral study. Results. In the article, protected natural areas are presented as the core areas and the surrounding areas as buffer zones under the relevant legislation. Riverbeds, mountain passes, trails, and forests which should be planted in the areas we offer, were considered as main factors during the construction of ecological corridors in the national park and the buffer zones. In this case, “least-cost” modelling was applied and ecological corridors were designated to ensure connectivity between core areas. As a result, the optimal ecological network model for the study area has been developed and mapped in the article. Conclusion. The high growth rate of consumption of natural resources led to the loss of biodiversity in the last decades. At present, it is important to take the necessary measures, and connectivity of ecosystems and natural complexes play an important role in sustainability. The presented model in the study can help to conserve biodiversity, reduce anthropogenic impacts, eliminate environmental barriers, and develop appropriate forms of land use.
