The Correlation Analysis of the Landsat TM Data,Its DerivedData,Meteorological Data and Topographic Data with theBiomass of the Tropical Forest Vegetation ofDifferent Forest
不同树种组的热带森林植被生物量与遥感地学数据之间的相关性分析

correlation analysis of the Landsat TM data, its derived data, meteorological data andtopographic data with the biomass of the tropical forest vegetation for the lithocarpus forest, the otherbroad leaf forest and the hard broad-leaf forest is explored here in Xishuangbanna, Yunnan province, P.R.of China. It includes four steps. Firstly, the biomass for each forest sample is calculated by using thefield inventory data of each sample. Secondly, GIS Database is established according the coordinate of eachforest sample. Secondly, Remote sensing image and its derived data, meteorological data, topographicaldata and the biomass of each sample are referenced to the same projection and coordination. Finally, thecorrelation between the Landsat TM and its derived data, meteorological data, topographical data and thebiomass is analyzed respectively for the lithocarpus forest, the other broad leaf forest and the hard broad-leaf forest. It is shown as follows: (1) The correlations of the biomass of lithocarpus forest and LandsatTM1,TM2,TM2,TM4,TM5,TM7,Bright,Green,Wet,VI3,DVI,PC1 and PVI are obvious at 0.05 level.(2) The correlation between the biomass of the other broad leaf forest and average rainfall per year isobvious at level 0.05. (3)The correlation of the biomass of the hard broad-leaf forest and average rainfallper year is obvious at level 0.05.Key words:
