It is crucial to pay close attention to the ecological security in land consolidation and utilization of coastal tidal areas and make an appropriate zoning scheme to meet the characteristics of its particular landscape. Landscape security patterns can identify the patterns that are crucial to the health and security of landscape ecological processes by analyzing and simulation them. This article applies the theory of landscape security pattern to land consolidation zoning in a coastal tidal area, Dafeng District, Yancheng, Jiangsu Province. The main landscape processes in land consolidation are explored in land consolidation in the area by literature review and field investigation, corresponding single landscape ecological security patterns are constructed using spatial analysis functions in ArcGIS 10.3, and land consolidation zones are determined according to the comprehensive landscape security pattern. The results show that: (1) The processes of water-soil conservation, water source protection, biodiversity conservation, local culture protection, and recreation are the main landscape processes. The security patterns generated by key points and resistance elements could affect land consolidation; (2) The comprehensive landscape security pattern is composed of the multi-landscape security patterns, which are classified into three levels of high, medium, and low. The areas of the levels account for 20.12%, 46.23% and 33.65% of Dafeng District, respectively; (3) The specific suggestions of ecological protection and ecological restoration in land consolidation are put forward for land consolidation zones with different levels of landscape security patterns. These results suggest that zoning based on landscape security patterns can provide guidance for land consolidation and regulation in coastal tidal areas.
