In order to speed up the development of rural economy, protect agricultural eco-environment and keep the ecological environment and economic development balanced in Suihua City of Heilongjiang Province, using the methods of entropy, evaluation and the model of coordinate development, the coordination between agricultural eco-environment and rural economy are analyzed based on the statistics of Heilongjiang Province and Suihua City in 2000-2009. Results indicate that the integrated development index for agricultural eco-environment and rural economy shows an upward trend, which implies that rural economic development is faster than agricultural eco-environment construction. The curve of coordinated development shows an up-ward trend, being the coordinated development with high quality.Before 2007, rural economic development was slower than agricultural eco-environment construction, whereas,from 2007, agricultural eco-environ-ment construction lagged behind rural economic development, which indicates that agricultural eco-environ-ment limits rural economic development at present.Some measures should be taken to deal with the “three wastes” pollution, to develop recycle economy in rural area, to use fertilizers and pesticides rationally and to reduce the pollution and destruction of agricultural eco-environment, so as to make agricultural eco-environ-ment develop with rural economy sustainably and harmoniously
