The paddy field ecosystem service function includes: rice and light industry raw material production; carbon sink; promoting the function of energy flow; promoting the function of the material cycle; maintaining the equilibrium of district ecosystem; providing natural environment esthetics and social, culture, science, education and spirit value; increase soil fertility. However, along the modern agricultural development, particularly the large quantity of agrochemical application such as fertilizer, chemicals, the growth regulates etc., the agriculture region and the plant and the water body at the edge is damaged, the wild living organisms was harmed, biodiversity was decreased, so the paddy field ecosystem was destroyed. Therefore enhance the service function of the paddy field ecosystem is a problem that modern agriculture must be solved. Experts suggest the technique of combine modern farming technique and modern cultural technique to raise fish, crabs, shrimps, ducks etc., thus strengthen the function of paddy ecosystem. This year, our province is popularizing this technique to further develop this intensified model and enhance the paddy ecosystem function.Based on the investigation of the ecosystem service function, this research aims to find the ways to enhance the paddy field ecosystem service function. Research results showed: fish cultivation can strengthen the soil ventilation, increase the paddy field fertility, increase the nutrition status, and increase the yield by about 10%, increase the supply of light industry raw material; Reduce to sun-burning of the paddy field in the course of rice production, promote the fish production without additional space, make the carbon sink function well, improve the ecosystem environment, clean water, strengthen the paddy field ecosystem resistant ability of the nature disasters, reduced the agrochemicals application, strengthened the paddy field ecosystem function of esthetics, social, culture, science, education, spirit value and maintain the equilibrium function of ecosystem in the district; Meanwhile, promote the function of the energy flow and material cycle of the paddy field ecosystem, therefore increasing the economic, ecological, and social benefit of the paddy field ecosystem, improved agricultural product quality and increase the farmer’s income. So, paddy field raising can greatly strengthen the paddy field ecosystem function.
