Net primary production and its spatial-temporal in Lu＇an mining area based on MODIS data
Abstract：Based on EOS/MODIS satelite remote sensing data and using spatial analysis module of ArcGIS9.3,analysed the temporal and spatial characters of vegetation NPP in Lu＇an mining area from 2001 to 2006.As to temporal heterogeneity,the net primary production from 2001 to 2003 is higher than 0.2 kg/m2 in most area while it is lower than 0.2 kg/m2 from 2004 to 2006.This significant decreasing trend deserves more attention.As to spatial heterogeneity,NPP pattern are closely related with both elevation and precipitation,but no direct relationship with latitude and longitude.The NPP data are up to 0.25 kg/m2 in low mountain and hill regions while NPP are less than 0.2 kg/m2 in plain or valley regions.The temporal changes of NPP are resulted from human activities,including coal mining and agriculture farming,while the spatial changes of NPP are related with natural factors,such as topography,vegetation types and precipitation,etc.
