【Abstract】 With continuous observation on long- term site, during Oct. 2000 to Oct. 2001, we had observed the floating vehicle of Road G210 within Niubeiliang National Nature Reserve period 04:00-22:00. The results show that, there were 65755 vehicles in observation days. The flux of vehicle is 782.8 vehicles per day, and the average is 1.37 vehicles per two minutes. The biggest flux of vehicle was recorded in the 15:00 everyday and the smallest in 06:00. The floating vehicles passed mainly in 09:00-22:00, the pass peak was 14:00-18:00. There are 4 periods of 04:00-07:00,07:00-13: 00,13:00-19:00 and 19:00-22:00 in every day. The floating vehicles was serious from 13:00 to 19:00, and it was medium from 19:00-22:00, 04:00-07:00 was extensive.更多还原
