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: 
(4-2) 
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
