Abstract: A mining eco-environment damage evaluation method, a mining eco-environment damage evaluation system, and a storable medium are provided. The method includes: acquiring a data source to obtain an eco-environment influence factor; obtaining evaluation index information of the mining eco-environment damage; constructing a mine ecological destruction and environmental pollution loss system; establishing n loss evaluation models; and performing loss calculation on different loss evaluation models, thereby realizing damage evaluation on the mining eco-environment. The method combines actual eco-environment problems, selects key evaluation indexes emphatically, and improves evaluation accuracy based on reducing evaluation calculation amount.

Abstract: A method and a system to analyze the driving relationship between ecosystem service and urban agglomeration development are provided. The spatial-temporal evolution characteristics of ESV in the Yangtze River Delta urban agglomeration are analyzed based on the revised equivalent value coefficient and land use data, the driving characteristics and the driving influence evolution characteristics of 10 indicators of human activities and natural conditions on ESV are explored through RF and SEM, an interaction relationship among influencing factors of ESV and the direct and indirect driving effect of the influencing factors on ESV are quantitatively measured under a unified framework, and the ESV evolution mode and the driving mechanism of the urban agglomeration are explored. The method can deeply study the interaction relationship among the influencing factors of the ESV, as well as the driving characteristics and driving paths of the driving factors to the ESV.

Abstract: The present disclosure provides a mechanical property detection device and a force detection system, and relates to the technical field of hydrate experiment equipment. The mechanical property detection device includes a reaction kettle, a thrust mechanism, and a force detection sensor; a reaction platform and a reaction frame provided on the reaction platform are provided in the reaction kettle, an end of the thrust mechanism extends into the reaction kettle, and can push the reaction frame to move relative to the reaction platform, and the force detection sensor is configured to detect magnitude of a thrust of the thrust mechanism when pushing the reaction frame, so as to solve the technical problems such as inconvenience in testing an adhesive force of gas hydrate in the prior art.
