To reduce the environment pollution risk from livestock and poultry breeding (LPB), it was necessary to control regional carrying capacity of livestock and poultry (CCLP). Landsat 8 images in March and July, 2016 was used to extract cultivated land area in Minhou County by using remote sensing (RS) technology. On this basis, CCLP of Minhou County in village scale was estimated by livestock and poultry density, livestock manure nitrogen (phosphorus) load of farmland, and the alarm value of pig manure equivalent load. The results showed that the total cultivated land area in Minhou County was 27665.11 ha and had a relative error of 3.08 % comparing to actual cultivated land area in Minhou County of 26838.00 ha. The results also indicated that the CCLP of Minhou County calculated by 4 index was different. Among them, the livestock and poultry density was the most stringent index, followed by the alarm value of pig manure equivalent load, livestock manure nitrogen load of farmland and livestock manure phosphorus load of farmland. Moreover, the result demonstrated that the maximum and minimum CCLP of Minhou County calculated by 4 indexes was all in Xitou village and Houcun village in Baisha Town. The results could provide a scientific basis for spatial layout of livestock and poultry breeding (LPB) and prevention of environmental pollution might be caused by LPB.
