Abstract:

Based on the research data of rural environmental changes of 467 rural households in 17 counties of 6 provinces of LowerandMiddle Reaches of the Yangtze River in the period of 2005～2010,this paper has established a differential equation model of rural environmental changes and its influencing factors in the process of modernization,and conducted an indepth analysis about the present condition and the affecting factors during the past five years.The results show that there is a decided downward trend of rural environmental quality indicators in LowerandMiddle Reaches of the Yangtze River of our country,and the conditions of rural areas in Middle Reaches of the Yangtze River represent a greater decline in rural environmental quality than that of the Lower Reaches of the Yangtze River,but agricultural production environment has marked improvement in Lower Reaches of the Yangtze River.The influencing factors of rural environmental quality changes in Lower and Middle Reaches of the Yangtze River are both homogeneous and also has difference.Homogeneous reflects in excessive development of natural resources and people’s weak awareness of environmental protection.Difference shows that the main influencing factors of rural environmental quality changes in Middle Reaches of the Yangtze River is that the process of urbanization and agricultural modernization speed up the falling of environment quality.But in Lower Reaches of the Yangtze River,population pressure, high degree of industrialization and the integration of urban and rural areas,rural areas facing superposition influence of life and industrial waste disposal,these factors caused a drop of rural environmental quality.The conclusion provides policy recommendations for the objective of “The Eleventh FiveYear” Plan which devoted to promote the simultaneous development of national industrialization,urbanization and agricultural modernization
