Detection of thermal pollution from power plants on China’s eastern coast using remote sensing data

摘要: The acceleration of the industrialization process in China has increased demand for electricity and triggered a power-plant building boom, especially along China’s eastern coast, where economy gets off early enjoys fast development. thermal plumes, residual chlorine, nuclides other pollutions produced by nuclear power plants have exerted an impact on coastal eco-environment. To monitor pollution from at Yueqing Bay this research, distribution sea surface temperature (SST) surrounding is obtained using SST retrieval methods developed Landsat Enhanced Thematic Mapper Plus (ETM+), HJ-1B infrared sensor (IRS) Terra moderate resolution imaging spectroradiometer (MODIS) data. comparison results before after operation indicates that total area waters impacted discharge two approximately 17.95 km2, with highest rise 4.5 °C appearing over around outlet Huaneng Yuhuan plant shore, whereas Zheneng western shore reaches 3.8 °C. intensity scope influence mainly depend installed capacity plants, terrain, tide. Although more than 3 not large, still bay ecosystems due to relatively closed nature environment. Due rising water temperatures reproduction individual evolution fish, shrimp, crabs, shellfish aquatic creatures, long term, will affect volume natural fishery biological resources throughout waters. quantitative also suggest relative MODIS data, ETM+ IRS data high spatial are applicable estimation small-scale SST, temporal helpful study spatio-temporal variability plumes plants.
