RESEARCH AND APPLICATION OF GIS AND DATA MINING TECHNOLOGY IN MONITORIG ANG ASSESSMENT OF NATURAL GEOGRAPHY ENVIRONMENT

At present, with the acceleration of the economic development process, the maintenance of the ecological environment has received extensive attention. In order to simplify the workflow of natural geographical environment monitoring and evaluation, this paper combines GIS technology and data mining technology, and builds a decision tree model with monitoring and evaluation as the core. Dongting Lake is taken as the research object to verify the validity of the model. The research results show that the algorithm designed in this paper can classify the land types of natural geographical environment and improve the accuracy of environmental monitoring and evaluation.
