Abstract:

Quercus variabilis which distributes widely in China has got a high starch content. The plant has been valued as a non-grain ethanol crop inland, but studies concerning the productive potential of ethanol from Quercus variabilis as well as its spatial distribution are not adequate. In this research, spatial distribution of Quercus variabilis based on spatial analysis techniques has been analyzed and the resource potential of Quercus variabilis ethanol has been quantified. Data on climate, soil, topography, land use and that from relevant literature about Quercus variabilis has utilized by ArcGIS. The results indicated that the proper distribution area of Quercus variabilis is wide(26 250.41×104hm2), and the total potential ethanol productivity is 270.90×104t·a-1-1 204.11×104t·a-1,which catered to 42.71% of the total ethanol demand in China. Thereinto not much unused land(1.53×104hm2)could be exploited which could lead to 0.88% of the total ethanol demand for E10 gasoline in China. The productive potential of ethanol could be increased by through selection of high yielding variety and boost of plant management to meet 41.21% of E10 demand all around China. Therefore, Quercus variabilis should be deemed as a critical raw material of fuel ethanol in the future.
