Evaluation and analysis of the exploitative intensity of mineral resources in Jiangxi province

The exploitative intensity of mineral resource can comprehensively reflect the status of mineral resource exploitative activities in the region, and has important guiding significance for the regional mineral sustainable development planning, and ecological environmental protection management.This paper takes Jiangxi province as the research area, collects 3 annual mineral resource development multi-source data, determines 3 categories, a total of 12 evaluation indicators based on the PSR model, and applies the fuzzy neural network method that can fuzz qualitative indicators to evaluate the exploitative intensity of mineral resources, and comprehensive analysis.During 2015 to 2019, the overall exploitative intensity of mineral resources in Jiangxi province decreased by 0.028 7.In 2019, Ganzhou city and Shangrao city had the highest exploitative intensity values, 0.098 1 and 0.092 1 respectively; Ji’an city and Nanchang city are the lowest, with 0.066 6 and 0.059 8; the exploitative intensity value of non-ferrous metal mines and energy mines are the highest at 0.732 3, 0.674 4, and special non-metals and other minerals are the lowest at 0.221 0, 0.217 0.The high-strength areas in the province are mainly northern Shangrao city, involving copper mines, Xinyu city and Pingxiang city in the central part, involving coal mines and iron mines, and Ganzhou city in the south, involving rare earth mines and tungsten mines.The research results are in good agreement with the actual mineral development situation.Based on the results, corresponding suggestions are made for the development of mineral resources in Jiangxi province.
