ABSTRACT
Alternative land use zoning scenarios provide guidance for sustainable land use controls. This study focused on an ecologically vulnerable catchment on the Loess Plateau in China, proposed a novel land use zoning model, and generated alternative zoning solutions to satisfy the various requirements of land use stakeholders and managers. This model combined multiple zoning objectives, i.e., maximum zoning suitability, maximum planning compatibility and maximum spatial compactness, with land use constraints by using goal programming technique, and employed a modified simulated annealing algorithm to search for the optimal zoning solutions. The land use zoning knowledge was incorporated into the initialisation operator and neighbourhood selection strategy of the simulated annealing algorithm to improve its efficiency. The case study indicates that the model is both effective and robust. Five optimal zoning scenarios of the study area were helpful for satisfying the requirements of land use controls in loess hilly regions, e.g., land use intensification, agricultural protection and environmental conservation.

Mentions: As a geographically contiguous part of administrative division, land use zones are divided based on land quality and natural, social and economic land use conditions, and have their own ordinances that prescribe what types of land use is allowable within them [12,13,14]. These zones bridge the gap between micro and macro land use controls, provide guidance in the case of conflicts between the various land use activities and determine the best land use options in practice [15]. Land use zoning towards sustainable development involves a set of sustainability objectives related to agricultural land prevention, ecological environment restoration, urban sprawl restriction and scattered rural settlement reclamation. Accordingly, nine different types of land use zones have been employed to regulate land use activities at the county scale in China, which is the major scale of Chinese land use planning and management [5,16]. According to the Chinese land use planning outline (2006–2020) at the county scale, these zones contain basic farmland preservation areas (BFPA), general agricultural land (GAL), forestry land (FL), pasture land (PL), urban construction land (UCL), rural construction land (RCL), independent industrial and mining land (IIML), tourism land (TL), and natural and humanistic preservation areas (NHLPA) [17]. Each type of zone is a combination of land units with approximate attribute values and can provide one type of land use regulations to policy makers and land managers. These zones have several characteristics in common, e.g., a zone may comprise some subregions (e.g.,and, separated by the unit) that are not spatially contiguous, but the land unitswithin each subregion are compact, and the minimum areas of subregions within each zone are correlated with the spatial scale in a zoning map (Figure 1).
