Simple Simulation of Abandoned Farmland Based on Multiagent Modeling Approach

摘要

In recent years, the agent-based model (ABM) has been widely applied and popularized in land-use and land-cover change (LUCC). It expresses the spatiotemporal heterogeneities of a model with individuals and ultimately obtains the emergence of individuals' behaviors on a macroscopic scale. This paper takes Taipusi Banner in the Inner Mongolia farming-pastoral zone as the study area based on local questionnaire data. The model synthesizes climate factors, the Grain for Green policy, direct subsidies of grain, and socioeconomic factors and simulates household farmland use behaviors in the next 30 years based on the Repastj toolbox in the Java language and in Eclipse. This model precisely reflects the LUCC process and its corresponding factors' interactions, provides deep insight into the integration process of these factors, and gives advice to governments on how to make land-use and food-security policies long-lasting and reasonable.
