Abstract :
It is significant for its water pollution control and estimation of wet land biomass to fast acquire space-time variation information of Dongping lake. This paper mainly researches the relative technologies of monitoring information on the variation of chlorophyll a concentrations using HJ-1A/1B image, such as, massive data auto- filter, image automatic preprocessing, chlorophyll a concentrations variable information monitoring etc. A processing flow of monitoring variation information of chlorophyll a concentrations, which applies to HJ image, is introduced. From the surveying result in 2009, using this processing flow could expeditiously discover the spatial-temporal variation regularity of chlorophyll a concentrations. The monitoring results could provide reliable data for the system of water quality pre-warning and estimating wetland biomass in Dongping lake.
