| 摘 要： | 以锡林郭勒盟为研究区域,将遥感技术用于草地地上生物量估算,分析了遥感植被指数与草地地上生物量之间的相关关系,比较和分析了三种植被指数的应用范围,研究了草地地上生物量遥感监测的方法,并利用遥感植被指数建立了草地地上生物量估算模型.研究表明:锡林郭勒草地地上生物量估产的植被指数是NDVI,其估产模型是"S"曲线,回归模型Y=e5.983-0.479/x(R=0.828, R2=0.685).

| Abstract: | The remote sensing technique was used to measure biomass in Xilinguole League. The correlation between the vegetation indices and the biomass was analyzed. Application range for three types of vegetation indices and biomass monitoring method by remote sensing was discussed. The results showed that NDVI has the best correlation to the region of Xilinguole; S regression is suitable for the region of Xilinguole. By the analysis of estimating errors in 2001 and 2005, the results show that the estimating errors accuracy of S regression model is 91.6~ in the region of Xilinguole in 2001 and that is 87. 1% in 2005. Models based on vegetation index were set up for estimating hiomass and dynamical vegetation monitoring in large area. |
