Abstract: The results of environmental monitoring and evaluation of soil, irrigation water and air in the pear production bases of Daweishan Town and Zhonghe Town in Liuyang City, Hunan Province showed that the 7 indexes of soil quality, 9 indexes of irrigation water quality, 4 indexes of air quality, and 27 indexes of fruit quality reached the standards set by the government regulation policy for production of “green pear”. The environmental conditions of the production bases completely fulfill the requirements for production of green fruit pears. However, cadmium, arsenic and volatile phenol may become the main pollutants in soil, irrigating water, and air in the pear production bases in the following years. Based on the current situation of the pear production bases, we propose to decrease cadmium and arsenic in the soils as well as suspending particles in the air by planting grasses, increasing vegetative coverage, and forbidding the use of arsenic preparation．
