为促进海滨湿地生态系统的健康可持续发展,以海滨湿地碱蓬为研究对象,利用便携式地物光谱仪测量碱蓬的反射光谱,应用称重法测定碱蓬的地上鲜生物量,定量分析碱蓬地上鲜生物量与其反射光谱变换形式之间的相关性,并应用线性或非线性模拟法构建海滨湿地碱蓬生物量估算模型.研究结果表明:碱蓬地上鲜生物量与变量(R800-R635)/(R800+R635)之间的相关性最大,以该变量构建的碱蓬生物量线性回归模型精度最高.该研究为海滨湿地脆弱生态定量遥感监测提供技术支撑.“,”In order to improve the healthy and sustainable development of coastal wetland ecosystem,the authors took Suaeda Salsa as investigated subject and acquired hyperspectral reflectance spectra of Suaeda Salsa and biomass data.The correlation was analyzed between biomass and reflectance spectra formation forms.The estimation models of Suaeda Salsa biomass were constructed based on those variables,which had relative higher relationship with biomass of Suaeda Salsa.The results indicated that the coefficient was the greatest between biomass and the variable named as (R800-R635)/(R800 + R635),and that the precision of estimation model based on the variable was the highest.The study will provide quantitative remote sensing technology applied in vulnerable coastal wetland ecosystem with technique support.
