Nuclear power industry had a great development in China in recent years and the environmental problems, such as thermal plume, has caused wide public concern. Taking the Hongyanhe nuclear power plant as example, this paper computed and achieved the sea surface temperature distribution with MODIS, HJ-1B and Landsat-8 thermal infrared data separately. These data were imaged in same time phase but different...
The reclamation in coastal areas has been playing an increasingly important role in expanding living space, which has aroused wild public concerns. With the increasing number of remote sensing images, the need to automatically achieve the precise coastline reflecting the status of reclamation has never been so urgent as it is now.

Ambient levels of formaldehyde and BTEX (benzene, toluene and xylene) compounds were monitored at seven residential areas in Xicheng District, Beijing, during the period of November-December 2009. Formaldehyde was collected using 2, 4 dinitmphenyihydmzine (DNPH) modified silica tube and analyzed by HPLC. BTEX compounds were collected with activated carbon tube and analyzed by GC-FID. The concentrations...
A 4-month data set was used to investigate historical changes between the number of the Cyanobacteria and concentrations of total nitrogen (TN), total phosphorus (TP), TN:TP, chemical oxygen dawdling (COD), NO3, pH and Chl-a in a shallow temperate zone lake (Guishui Lake, Beijing, China). The aim was to evaluate changes in the risk of Cyanobacteria blooms, which have occurred several times in the...
