Based on land use maps interpreted from remote sensing image of 1974,1987 and 2003,as well as GIS technology combining with the method of mathematical statistics,taking the northern part of the Ailao Mountains as the case study area,the characteristics of dynamic change of land use were analyzed in this paper.

The study of composition and physico-chemical characteristics of fluid inclusions from three gold deposits hosted in the Ailaoshan gold mineralization belt indicated that the ore-forming fluid was characterized as being rich in Na+, K+, Cl-,SO2-4,F-and CO2, and belongs to the Na type solution, epi- to mesothermal in nature, moderately saline, intermediate to weak alkaline, and relatively reducing.
