GOLD-ORE RESOURCES ASSESSMENT OF SOUTH NINGXIA BASED ON GIS AND RELATED MATHEMATICAL MODELS

This article mainly discusses gold r esources appraisement of south Ningxia based on ArcView platform.In appraisal process,spatial data a re edited,managed and analyzed in th e platform,a gold ore resource location appraisal model is built through Ave nue,which is a secondary developmen t language of ArcView,and a gold ore resource quantity appraisal model i s built through Visual C program,at t he same time,the resource quantity appraisal model has a little impact coupling with ArcView.The models ful fill an ore deposit location assessm ent and gold ore resources assessment succe ssfully,and bring forward an assessment outcome and work suggestions fo r production departments.Furthermo re,it offers us a new method and thought for GIS applying in ore resources assessment of West China.
