| 摘 要： | 本文以SPOT6 高空间分辨率遥感影像为数据源,通过植被覆盖度和地上生物量两个参数进行滩涂湿地入侵种互花米草植株高度的估算研究。结果表明,三沙湾滩涂湿地互花米草植株高度平均值为2.04 m,以1~2 m和2~3 m植株为主要分布高度,分布面积分别为6.83 km2和10.31 km2,占研究区互花米草总面积的33.83%和51.06%,小于1 m和大于3 m的互花米草仅占9.26%和5.84%。估算值与真实值之间的均方根误差为0.204,绝对误差为0.04~0.37 m。该方法是对高空间分辨率光学影像应用研究的重要尝试,其反演方法具有较好的可行性,可较为准确的获取滩涂湿地植株高度信息。

| 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. |
