Abstract

Abstract

In this paper,plant height of invaded Spartina alterniflora in the coastal wetland was studied through fractional vegetation cover and aboveground biomass by using SPOT6 high spatial resolution satellite data. Results showed that,the average plant height was 2.04 m,most of the plant heights were between 1 m to 2 m and 2 m to 3 m,with distribution area of 6.83 km² and 10.31 km² respectively,accounting for about 33.83% and 51.06% of the total S.alterniflora area. While,plant height value less than 1 m and more than 3 m accounted for about 9.26% and 5.84% only. Root mean square error of estimated and measured value of S.alterniflora plant height was 0.204,and absolute error was between 0.04 m to 0.37 m. This study was an important test in high spatial resolution optical image application,obtained more accurate plant height in coastal wetland,and had good feasibility.
