| 摘 要： | 以Landsat TM影像和高分一号影像为数据源,结合外业实测数据,利用遥感影像和实测数据建立崂山林场生物量多元线性反演模型,比较分析不同数据源下反演出的模型精度,估测了崂山林场森林生物量。研究发现,利TM遥感影像作为数据源的崂山林场森林生物量反演模型平均精度为77.12%。高分一号遥感数据反演的生物量模型平均反演精度达到80.75%,高于TM数据源下的生物量反演模型精度。分别根据TM遥感影像和高分一号遥感影像林分生物量估测模型,估测的崂山林场2009年的林分生物量为401185.62t,2013年的林分生物量为402485.44t。

| Abstract: | Based on Landsat TM image and GaoFeng NO.1 image as data sources,combining with the actual measured data to establish Laoshan forest farm sample biomass multivariate linear inversion model by using multivariate linear relationship between remote sensing data and measured data.Through a comparative analysis of different data source‘s model accuracy to estimate biomass of farm Laoshan.Through the study found that using the TM remote sensing image as data source,The inversion model average accuracy of farm Laoshan is 77.12%.Using GaoFeng No.1,the average inversion accuracy is 80.75%,significantly higher than the biomass inversion model in the case of the TM data accuracy.Estimation models are based on TM images and Gaofeng NO.1 images stand biomass estimation Laoshan Forest Biomass in 2009 was 401185.2tons,in 2013the stand biomass was 402485.44 tons. |
