Study on the Temporal and Spatial Characteristics of Rural Industry Pollution Based on Pollution Degree

Herein we report the division of rural industry based on the different level of pollution,and the characteristics of spatiotemporal diversity with the evolution of rural industrial structure.Further,we discuss the mechanism of environmental impact and establish environment effect index in order to quantitatively evaluate the environmental pollution effect.The main conclusions are as follows:①The proportion of the light pollution rural industries revealed an increasing tendency from 1988to 2010,accordingly is the decline of the heavy pollution industries.The environmental effect index presents a trend of growth-decline-growth,and has been gradually increased since 2002.②The construction of rural industries had obviously regional difference between the developed eastern region and mid-west regions.At the provincial level,Jiangsu,Shandong,Zhejiang,Shanxi,Hebei,Henan,Guangdong,Liaoning,Shanghai account for a large proportion of heavy pollution industries and moderate pollution industries,these result in a large values in the environmental effect indexes,which is in complete agreement with the effect of regional level.In conclusion,we think different management measures in different regions should be implemented.
