Abstract: It is a typical and representative in the country that coal mining has been causing farmland subsided deeply and submerged in water seriously in Jining City.Using the combined methods of high-resolution remote sensing (RS) to obtain information and geographical information system (GIS) to analyze spatially，under the support of land use map，mine distribution map，administrative zoning map，coal mining subsidence land survey and statistic data，the information of coal mining subsidence farmland submerged in water in Jining City since coal mining to the year of 2009 were extracted with the man-computer interactive interpreting method.The results showed that: the perennial water farmland area of cola mining subsidence land was 4 780.49 hm2，accounted for 0.78% of the total area of cultivated land in Jining City，the governance and non-governance subsided farmland submerged in water accounted for 57.84% and 42.16% of the perennial water farmland area，respectively.The subsidence farmland submerged in water mainly distributed in the “Golden Triangle” junction of Qufu City，Yanzhou City and Zoucheng City，the southern Rencheng Distinct and the central region of Weishan County; And its distribution was irregular，a mine with a subsided farmland submerged in water or a mine with two or more subsided farmlands submerged in water.The findings provided a scientific basis for the local government to strengthen the real-time monitoring of the subsided farmlands submerged in water and formulated scientifically the reclamation scheme of the subsidence farmland submerged in water.
