摘要：CSS stands for C ity S imulation S hell. CSS is a menu driven shell for simulating the growth of the city, developed using Arc Macro Language (AML) of Arc/Info GIS. It generates different simulated city models in a semi-automated way. Urban areas in the country are rapidly growing and thus there is a need to monitor the growth and changes in urban land use pattern over time. These inputs are helpful for planning the city in a sustainable manner utilizing natural resources and facilities optimally. While preparing the Master Plan of the city, one needs to do various projections related to population and physical growth of urban built-up land. It is in this context, the simulation exercises are helpful to predict the future growth of the city based up on the past growth. An attempt has been made in this study to simulate the future growth based upon the past growth of the city employing a multi-parametric approach. In the present study, a semi-automated shell for city growth simulation has been developed. The concept behind the shell is to simulate the future growth of the city based upon the past growth of the city employing a multi-parameter approach. The input required for the shell is the composite layer having all the characteristics of physical parameters like existing land use pattern, slope, soil, water availability, transportation network and natural hazards etc. Since in order to predict the future growth, urban land requirement is needed and for that population for the required time is needed. This shell gives the user the flexibility to either give the population as input or user can give only present population and the shell will provide the population for the required time. Based on that projected population and population density, calculation of the land needed for the urban growth and the allocation of that land will be done by the shell automatically. Hence, the output of the shell is simulated city for the given period. Using this shell, growth of any city can be simulated by slightly modifying the parameters used and criteria. This shell also provides the facility to use either the standard criteria or user defined criteria. Also, there is an option to select the urban suitable classes for the land allocation process so that different simulated city models can be generated. The output of the shell also includes the land required for the city growth
