4.1.2 Analysis of space sequence
The purpose is to reflect the given periods area of land use
change in the spatial distribution of the difference, Land use
changes there are significant regional differences We can use
the regional land-use changes in the relative rate of the
different land-use change to reflect the regional differences.
Here we use a single type of land use changes in the relative
rate to reflect the land-use change in the number of types of
regional differences a regional study area within a specific land
use types relative rate of change might be changing regional
disparities:

Ka, Kb represent the regional land-use study with the initial
and end of the study area, Ca. Cb behalf of the entire study area
land-use studies and beginning the end of the study area. If the
relative rate of change Repeatability, said changes in the region
over the entire domain.
Using the above formula can be studied in all areas of the mine
construction area relative changes in the rate of farmland and

Table.4-3.Relative of change of farmland and greenbelt area
From the above two forms, as can be seen in the mines and the
establishment of the early establishment of five to ten years,
Mine land for the construction of a substantial increase in the
area, the relative rate of change is greater than one, at the same
time, land for the construction of the increase will bring an area
of farmland and open space reduction, Farmland and open
space so the relative changes in the rate of greater than one, in
the mines and the establishment of the early period of
development in particular. Mine steady period, the construction
site in the rate of increase slowed, Because of the mining area
of arable land and ecological environment protection of the
increase, farmland and open space the size of a gradual pick up
the relative rate of change began over building sites. These
conclusions are consistent with the realities of development in
the mining area is characterized by basic proved the reliability
of the analysis.
4.2Analysis of driving force of mine land change
Land use change is aroused by natural, economic and social
factors and so on; driving force is the dynamics in-depth to
change the study of the residents of land-use change internal
rules. Driving mechanism can predict future trends and the
development of sustainable land use planning basis, study of
driving force is the reasonable basis to adjust the relation
between person and nature.
4.2.1 Regression analysis
Regression analysis is a statistical method, it is an objective
existence interrelated phenomena, choose a suitable form of a
mathematical model to express the phenomenon of the average
change in the number of relationships According to its relations.
If two or more of a comparison have close correlation, a major
phenomenon is caused by the changes. It can take advantage of
