An Agent-Based Reasoning of Impacts of Regional Climate Changes on Land Use Changes in the Three-River Headwaters Region of China

Table 1

The factors that impact the agents’ behaviors.

Categories	Variables	Impacts on behaviors
Climate	Temperature	Different climatic conditions determine the agents’ land use practices; for example, mild climate is suitable for cropping, pasturing, and so forth.
	Precipitation
Economy	Initial account	The amount of the agents’ account impacts their land use practice, such as investment, land bid, and cost control.
	Nonagricultural income
	Price
Bad events	Natural disasters	Weight of balancing the economy and nature.
Policy	GFG	The compensation can stimulate the agents to transform other land uses into grassland and forest land.
	Nature reserve	Ban the agents’ land use practices in the core area.
Topography	Distance to water	The conversion area of grassland to cultivated land decreases with the increment of distance to water and slope.
	Slope
Soil property	Soil nitrogen	Agents are willing to keep the fertile land parcel as grassland.
	Soil phosphorous
	Soil potassium
Land use	Land use	The initial land use determines the results of next step.; The land use type and area determine the probabilities of land use change.
