The invention discloses a mine ecological safety identification method based on a convolutional neural network model, and relates to the technical field of mine ecological safety identification. A convolutional neural network CNN is introduced to automatically optimize a resistance value, a time dimension and a dynamic factor are combined, and a resistance surface is monitored and adjusted in real time, so that the safety of mine ecological safety identification is improved. The method can dynamically respond to the influence of topographic change, vegetation density fluctuation and meteorological change, can capture the real-time influence of sudden rainfall, mining area extension or vegetation restoration and the like, the generated resistance surface has high timeliness and accurately reflects the dynamic characteristics of an ecological system, and meanwhile, the circuit theory and deep learning are combined, so that the method can be widely applied to the field of ecological engineering. According to the method, multiple potential migration paths are generated, dependence on a single minimum resistance path is avoided, more diversified migration choices are provided, path weights are dynamically optimized in combination with a time sequence model, channels with high ecological values and high migration requirements are preferentially protected, and it is guaranteed that a migration network has enough elasticity and adaptability.

The invention discloses an invasive organism selenium-rich compost formula and a preparation method. According to the invading organism selenium-rich compost formula, an invading plant mikania micrantha and invading animal ampullaria gigas meat are used as compost raw materials, and selenium elements in different forms are used as selenium sources. The compost formula can prolong the high-temperature period of the compost, accelerate the composting process, degrade more and more organic substances, increase the nutrient content of the compost and reduce the emission of greenhouse gases in the composting process; therefore, the problems of short high-temperature period duration, low organic matter degradation efficiency and greenhouse gas emission in the traditional composting process are solved. The invention not only provides a new method for resource utilization of invasive organisms, but also enables the compost to have higher nutritional value and ecological value through an exogenous selenium application mode.
