Abstract:

Delimiting ecological protection redlines, basic farmland protection zones, and urban growth boundaries is particularly crucial in coordinating urban land use and implementing the "integration of multi-planning." The purpose of this article is to explore the concept, spatial pattern, and influencing factors of "three lines" conflict at land parcel level, and to improve the theoretical framework and analytical methods of "multiple plans conflict" and "multiple plans integration." First, the connotation of "three lines" and "three lines" conflict are clarified by analyzing the essence of land use conflict and the three lines conflict index (TLCI) was constructed to characterize the intensity of the "three lines" conflict. A spatial overlay operation is performed on the "three lines" using ArcGIS software to produce the spatial distributions of "three lines" conflict of Wuhan City. Then we analyze the spatial pattern of three "three lines" conflict using a host of spatial pattern analysis methods (including spatial autocorrelation analysis, gradient analysis, and landscape pattern analysis). Finally, we identify the influencing factors of "three lines" conflict from the perspectives of socioeconomic status, natural environment conditions, and location factors using correlation analysis. The results indicate that: (1) Conflicts between ecological protection redlines and basic farmland protection zones, and conflicts between ecological protection redlines and urban growth boundaries are the main types of "three lines" conflict, accounting for 6.57% and 5.77% of the regional land areas, respectively in the Wuhan metropolitan area, and conflicts between farmland protection zones and urban growth boundaries are relatively few. (2) Spatial distributions of the three types of "three lines" conflict are different. Conflicts between ecological protection redlines and basic farmland protection zones are mainly distributed in the periphery of the Wuhan metropolitan area. Conflicts between ecological protection redlines and urban growth boundaries are mainly distributed in the core of the Wuhan metropolitan area. Conflicts between basic farmland protection zones and urban growth boundaries are mainly distributed in the transitional zone between the urban and rural ecotones. (3) The six indicators representing regional conditions have different effects on the intensity of the three types of conflicts. In conclusion, TLCI is a good measurement of regional comprehensive "three lines" conflict intensity. The spatial pattern analysis methods can well describe the characteristics of the "three lines" conflict. (3) The research on the formation mechanism and driving factors of "three lines" conflict needs to be further explored. This study can provide a systematic framework for analyzing "three lines" conflict and guidance to landscape planning for avoiding "multiple plans conflict."
