A number of biological processes, such as invasive plant species and cell migration, are composed of two key mechanisms: motility and reproduction. Due to the spatially exclusive interacting behavior of these processes a cellular automata (CA) model is specified to simulate a one-dimensional invasion process. Three (independence, Poisson, and 2D-Markov chain) approximations are considered that ...

Projections and predictions of urban growth provide information that can lead to a certain level preparedness for making cities resilient sustainable. To ascertain the degree confidence in predicting growth, this paper back-tests Cellular Automata (CA)-Markov Prediction Model (PM) by comparing results model 2010 2020 with actual land-use patterns Isparta same years. The data used are Landsat im...

This paper investigates the potential of a cellular automata (CA) model based on logistic regression (logit) and Markov Chain Monte Carlo (MCMC) to simulate the dynamics of urban growth. The model assesses urbanization likelihood based on (i) a set of urban development driving forces (calibrated based on logit) and (ii) the land-use of neighboring cells (calibrated based on MCMC). An innovative...

Conversion rule is a key element for cellular automata (CA) model, and it significant challenging issue both domestic international experts. Traditional research regarding CA models often constructs single conversion the entire study area, without differentiating on basis of unique growth features each location. On this, partitioned heterogeneous land-use simulation model (PHLUS) constructed by...

In order to promote the healthy development of Nanchang city in future and maintain virtuous cycle urban ecosystem, this paper uses CA-Markov model simulate forecast land use 2030 explore urbanization process city. Firstly, changes from 2000 2020 are described, followed by simulations for as a verification accuracy, projections based on accuracy requirements. The results show that: (1) rate exp...
