The results show that ecological pressure index increased from -1.089 to 1.363 and an increasing trend on the whole was exhibited during 2000-2009, especially after 2006, the ecological pressure grew in a straight line. Population density, industrial waste water discharge and chemical fertilizer consumption are the important factors influencing the ecological pressure index.
