Abstract：As a kind of natural and environmental paving materials, the solid wood flooring has become popular among people whose demand is increasing day by day. However, how to understand and detect wood properties quickly has been a urgent problem to be solved for material selection and quality inspection. So the profile densities of two kinds of import solid wood floorings made of Dipteryx odorata，Pometia spp. were quickly detected for physical properties and major chemical compositions by using rapid detection technology, X-ray scanning method and fourier transfoum infrared spectrum(FTIR). At the same time，the basic density of wood was measured by direct measurement and we also analyzed the correlation between the rapid detection density and the basic density of the two kinds floors. The profile density results showed that the density of Dipteryx odorata was higher than that of Pometia spp. and the heterogeneity of two kinds solid wood were great，correlation analysis data showed that there was a high correlation between the average of profile density and the basic density，the correlation coefficients of fitted parameters were 0.983 and 0.981，respectively. Besides the correlation coefficients of all materials was 0.991. The FTIR results showed that the extracts of Dipteryx odorata was higher than that of Pometia spp.，the lignin characteristic peaks intensity ratio of I1 507/I1 425，I1 507/I1 740 of Dipteryx odorata was higher thanthat of Pometia spp.，while the cellulose characteristic peaks intensity ratio of I1 507/I1 425，I1 507/I1 740 was less than that of Pometia spp.. The results showed that the lignin content of Dipteryx odorata was higher than that of Pometia spp.，while the cellulose content was less than that of Pometia spp. Thus，the X-ray scanning method can quickly detect the heterogeneity of the wood and also can predict the basic density. While the FTIR can quickly detect the relative content of wood chemical components，so the combination of the two methods can detect the physical and chemical properties of solid floor woods and other lumbers rapidly.
