英文摘要： In the recent years, the serious incidents about heavy metal pollution caused by mining and industrial production had frequently happened in China. It made the life and health of the local residents some kinds of severe harm. Consequently, it is very necessary and has important significance that to carry out the research of heavy metal pollution. The hyperspectral remote sensing is a frontal area in the application research of remote sensing technology nowadays, and the analysis and evaluation of environment during the exploiting and mining of mineral resources are the hot and difficult issues of hyperspectral remote sensing applications. The Research work will take the Zijin's gold-copper mining areas in Fujian province as a case study area, and applies space-borne hyperspectral remote sensing and surface spectral measuring to acquire the micro-pollution information of heavy metal such as copper (Cu) or lead (Pb) especially to soil and vegetation in the study area. The key theories and technologies include (1) how to define the heavy metal spectral response intervals effectively; (2) the algorithm of wavelet packet transformation of hyperspectral image data of heavy metal environment pollution; (3) the spectral decomposition and explanation of linear wavelet packet transformation in frequency domain of micro-p
