In the economic development of the new normal and construction of ‘Beautiful China’ requirements, delimiting the basic farmland protection red line, urban growth boundary and ecological protection red line (e.g. three lines) scientifically is needed for coordinating production-life-ecology spaces, allocating land resources and optimizing patterns of urban landscapes. Based on analysis and understanding of connotation of these three lines, we put forward an analysis framework and coordination strategy, and selects Jintan District in Changzhou, Jiangsu as a case study. By constructing an ecological-farming-construction oriented land suitability assessment system, we analyzed the suitability of land use under different target interest orientation and identified the land use conflict zone using comprehensive suitability evaluation results. The principle of ecological priority, concentration, neighborhood harmony and space recognition, therefore, can couple and coordinate each type of conflict zone and provide new ideas to delimit the three lines. We found that the ecological protection red line in Jintan District is mainly distributed in the west of Maoshan area and Tianhuang lake wetland in the north, Qianzi lake and Changdang lake area, with a total area of 260.63 km2. The basic farmland area is 303.57 km2, mainly distributed in the east side of the Maoshan area and the low hills, central alluvial lake plow plain and eastern high-Kang plain. The urban growth boundary delineates the maximum extent of the central city'’ expansion, with a total area of 69.43 km2.

Key words: basic farmland protection red line, urban growth boundary, ecological protection red line, land use conflict, coupling coordination, Jintan District in Changzhou
