Computer-Based Estimation System for Land Productivity - Advanced Research on Computer Education, Simulation and Modeling - page 321

The estimation of land productivity is found by substituting K 1 and K 2 into the land
productivity calculation formula.
4 Summary
Land productivity is one of the important indices in the assessment of effects of the
dynamics of land system change. The ESLP is a collection of several application pro-
grams, including land suitability assessment, the evaluation of land productivity, and
some advanced applications which use the stock of land resources as the fundamental
input information. The ESLP involves numerous parameters in the process of land
productivity estimation, and the calculation processes are lengthy and complex. This
chapter describes the processes, parameters needed and methods of data preparation,
which will improve the ability of readers to use this model and provide a foundation for
its wide application.
