Application of Game Analysis and Mathematical Optimization Model in Soil Fertility Evaluation Intelligent Monitoring System

Based on the study of various game analysis and mathematical optimization, this paper establishes a hierarchical structure model, uses weighted C4.5 and weighted DBSCAN algorithms for soil analysis and evaluation, and develops and designs a soil fertility evaluation system based on J2EE technology. Based on game theory, by analyzing the KMRW reputation game between environmental supervision departments and enterprises, the game of illegal reporting by intermediaries and the game of due diligence by government supervision departments, the soil pH value has dropped from 1981 to 2006 for 26 years. 23 units, the soil organic matter content decreased from 21.5 gk in 1981 to 14.1 gk in 2006, a decrease of 35.3%; the contents of soil total nitrogen, alkali-hydrolyzable nitrogen, available phosphorus and available potassium were significantly rise.
