Abstract: Affected by the development of society and economy and people's needs, the cognition of cultivated land function has gradually changed from single production function to a synthesis of production function,ecological function,landscape function,social function and other functions. The multifunctionality of cultivated land has become a research hot spot issue. Many studies have focused on the evaluation and analysis of a single function, which lack of links between different functions. To identify the association degree of various functions of cultivated land and the correlation in different spaces, based on land utilization alteration data and statistical yearbook data,using cold hot spot analysis and partial correlation analysis to quantitatively analyze the production function, ecological function and landscape function of cultivated land in Qingpu District, Shanghai and classify five dominant functional areas to identify spatial association of whole district and each dominant functional areas. The results showed that:(1) The spatial distribution of each function of cultivated land was significantly different. The distribution of production function and ecological function showed a trend of high in east and low in west,the landscape function was opposite,which was high in west and low in east. On the whole, the cultivated land multifunction was better in the east and the north was poor.(2)Advantage area of production function, ecological function and landscape function were mainly distributed in the northeast, southeast, southwest and north, the inferior areas of all functions were concentrated in the northwest,no significant functional areas centered around Dianshan Lake.(3)In the whole area, it showed a synergistic relationship in production-ecology function and production-landscape function,it had a trade-off relationship in ecology-landscape function,the correlation was obviously different in each dominant function area that compared with the whole area.The conclusion showed that: There were significant trade-offs and synergies relationship between the functions of cultivated land and some differences in each dominant functional region. By analyzing the spatial distribution differences and correlations of arable land various function, slowed down the trade-off relationship and enhanced the synergy relationship between multifunction and targeted protection can be carried out to achieve sustainable use of cultivated land.
