Remote sensing invertion of groundwater level in Yuka-Dachaidan basin delta area of Qinghai province
摘要
Abstract
The purpose is to get the situation of groundwater level distribution in Yuka-Dachaidan basin delta area in Qinghai province by data of satellite remote sensing.The paper obtained NDVI by use of TM8 data,and retrived land surface temperature ( TS ) from atmospheric transmission equation to con-struct TS-NDVI space.The temperature vegetation dryness index ( TVDI) was obtained and topsoil mois-ture was retrieved by using TVDI.In arid and semi-arid regions,the topsoil moisture and TVDI are de-pended on groundwater level , so the groundwater level distribution can be calculated through the correla-tion between the topsoil moisture ,TVDI and groundwater level.The result is in accordance with actual. The correlation coefficients of groundwater depth obtained by soil moisture and TVDI ,and by measurement are 0.83 and 0.765 respectively.关键词
