Paper Abstract

In the paper brings forward that complexity degree of land use structure can be used as one of quantitative indices to define the land use/land cover (LU/LC) status expression precision scale. Then by simulating population density spatial differences in Wuhan district, according to the value of complexity degree of land use structure, divides the experiment area into a kind of non-uniform and multi-grid structure. Consulting one grid cells' status high or low in the multi-hierarchy data structure, the LU/LC status expression precision scale rough or fine can be defined in a degree. Furthermore, the outcome of simulating population density shows that the multi-grids land data structure can integrate land use data with other social and economic statistics conveniently and neatly to complete some simple land data mining tasks such as the data computation or analysis effectively, then can reflect the LU/LC status of some region.
