英文摘要 | The remote sensing pollution mechanism in soil pollution-Cd is discussed depending on the research into the chlorophyll content of rice leaf polluted-Cd in this paper. The response models of remote sensing information parameters, which reflected chlorophyll content variety of rice canopy, with soil Cd pollution degree are established based on Hyperion satellite data and a great number of ground experiment data. To extract sensitive remote sensing parameter to Cd pollution, multiple discriminant analysis (MDA). was applied over the data. Experiment indicated that MCARI is the most sensitive parameter to the chlorophyll content of rice polluted-Cd, which response coefficient is 0.59. The research result showed that the pollution monitoring of Cd element in soil in large area might carry on initially according to this model, because different Cd pollution degree is in different position in the model, however, the precision of pollution model need be improved.; Computer Science, Interdisciplinary Applications; Environmental Sciences; Geography, Physical; Remote Sensing; Telecommunications; CPCI-S(ISTP); 0 |
