Abstract. A set of algorithm stored into the Dynamics of Land System (DLS)
model is a collection of program that simulates pattern change of land uses by
conducting scenario analysis of the area of land use change. In this paper we
show that the model analyzes causes of the dynamics of land use pattern, simu-
lates the process of land use changes and assists land use planning and land
management decisions. We introduce the main procedures of DLS including
framework, parameter configuration, function modules and results output.
Keywords: Algorithm, Simulate, Parameter configuration, DLS.
1 Framework
The DLS model fully considers the links between related models of nature, ecology and
economy. It also extracts decision-making reference information used in land use
planning, environmental planning and management of natural resources by designing
different scenarios of changing regional land use area [1, 2]. Users of the DLS model
can input nonlinear demand change, different conversion rules and driving factors at
different pattern changes of land uses to simulate and analyze the complex changes of
regional land use patterns. The DLS model also considers the influence of macroscopic
factors such as topography, environment, trade and institutional arrangement and land
management policies to more accurately simulate possible scenarios of pattern changes
of land uses.
2 Function Modules
The DLS model is based on quantitative analysis of land use pattern changes at the pixel
level, interactions among driving factors and spatial-temporal distribution of land use
pattern change [3]. It simulates the pattern changes of regional land uses by analyzing
