%X In order to study the influence of different bandwidth's remote sensing data on estimating chlorophyll-a concentration in waters,this paper analyzes and calculates the correlation coefficient between normalized reflectance of different bandwidth and chlorophyll-a concentration based on real-measurement hyperspectral reflectance.With constant increase of bandwidth in a scope of 75.93nm,it has found that the maximum correlation coefficient decreases by degrees,the maximum positive correlation band moves to long wave,the maximum negative correlation band moves to short wave while estimating chlorophyll-a concentration in waters.As the bandwidth changes in the scope of 31.60nm,both the maximum positive correlation band and the maximum negative correlation band will keep a relative stable state.Finally,through contrasting the mean and standard deviation of different bandwidth's correlation coefficient,we think 723.51nm~733.00nm is the best band range for estimating chlorophyll-a concentration.This will provide important reference value for band setting of remote sensing sensor and band choosing of real chlorophyll-a estimation by remote sensing in water.
