Abstract

Compared with megacity, the medium-sized city is playing a more and more important part in the rapid urbanization process in China. Due to the expanding scale of the medium-sized city, urban growth is sprawl and this way leads to ecological, social and environment problems that are unsustainable. To measure the urban growth of the medium sized city, cellular automata (CA) model is employed. CA has proven to be a popular and effective modeling approach to investigate dynamic urban growth systems and for evaluating the impacts of possible policy options. We use the SLEUTH model, which is a well known CA model, to simulate the future urban growth of Huaian, Jiangsu province of China. The results confirm the value of SLEUTH which provides a rich exploratory of knowledge for evaluating the effects of possible decision-making in local government.

Highlights

In the twenty-first century, the large cities of China are confronted with great challenges of environment and development inevitably
Two calibrations and forecasts of urbanization and land use change were completed for Huaian city
The first calibration and forecast used all of the data, aggregating the land use data into urban/non-urban, and the second, the data was disaggregated into six land use categories

Summary

Introduction

In the twenty-first century, the large cities of China are confronted with great challenges of environment and development inevitably. The National Ministry of Science and Technology of China decided to explore the coordinated development model of population, environment and resources in the process of Industrialization and Urbanization in the medium-sized and small-sized cities, which make up 56 percent of the city’s total, in 1986. Developmental experts agree that a sustainable city should meet the needs of the present without sacrificing the ability of future generations to meet their own needs. The ambiguity within this idea leads to a great deal of variation in terms of how cities carry out their attempts to become sustainable [2]. We focus on two of the most pressing issues that are directly affected by the urban form: management of urban planning and the conversion of surrounding agriculture and natural land
