APPLICATION OF REMOTE SENSING TECHNIQUE ON LOCATING UNDERGROUND WATER IN MINFENG DISTRICT IN XING JIANG AUTO-NOMOUS REGION

The model for locating underground water has been set up applying remote sensing technique,on the basis of interpreting reflections of landscape,hydrographichal,ancient river course in the desert area in Minfeng District,Xinjiang Autonomous Region.The bright red color reflection is interpreted as vegetation community fond of fresh water and dump soil that stands for broadleaf vegetation rich in chlorophyll.They are distributed in riverbed,flood land and ancient river course area which is abundant in fresh water.The brown red and purple red reflection is interpreted as vegetation fond of salt-water damp soil that stands for salt-resistant little leaf and thorn vegetation community.This vegetation community is distributed in salt-water areas,such as salt swamp and salt basins.The red tiny spot reflection is interpreted as drought-resistant vegetation community that stands for jungle vegetation.They are distributed in stable and unstable sand hills.Whose water level is very deep.Then the overflowing area and charging area is decided.The mineral density of underground water increases from less than 1 g/L to 5~7 g/L from the south to the north.At last the underground water source fit for exploring is found in the desert fringe of Mingfeng and Yutang District.
