In this paper, we use regression analysis of multivariate linear

construction sites X5.
Use each type of factor and cultivated areas for stepwise
regression analysis, to determine the coefficient of such factors
contribution rate arable land area by regression equations of the
variable in order to determine changes in the main driving
factors. Process to take into account various indicators
dimensional data volume is relatively varied more, so first of
all make raw data standardization by formula.
4.2.2 Establish driving model
We make experiment based on the statistical of the study area
during 1976-2005, take a land type for example, select an area
of arable land due to variable Y, and choose five categories,
eight indicators as independent variables to analyze its driving
mechanism: population category (the local population XI1,
agricultural population XI2, the number of total households
X13). Economic output (total agricultural output X21,
industrial output X22), the standard of living (per capita

Ya is the dimensionless data for non-dimensional data, the
average variable Syy is the deviation of the square and square
root. The following table by the above formula standardized
data:

By the use of standardized statistical data table stepwise
regression analysis, obtained the regression equation:

We can see that total population end of year; construction land
and collapse area and agriculture have very important relation
with the change of arable land, population end of year, the total
output value of agriculture and farmland area is a positive
correlation, and the collapse area, Construction sites, with the
area of cultivated land is a negative correlation, it note that the
increase in population and the increase in agricultural output
led to the increase in the amount of arable land, and the
collapse area and the construction area will inevitably lead to
an increase in the decrease in the amount of arable land, And
these two factors on changes in land area is greater than that of
the local population and total output value of agriculture, Total
causing the result of the decrease in arable land area. However,
we still see a positive side, that the population and agricultural
output value of the two drivers factor also plays an important
role, This shows that the state of agricultural and rural
investment is increasing, and especially for mine land
reclamation and reconstruction increased the intensity of the
treatment, it is gratifying. In addition, we also note that mining
subsidence factor is cultivated acreage change the dominant
factor, it is the need to reduce the coal mining subsidence and
subsidence areas have land structure, this is the significance of
the study lies.

land use drivers analysis found: Mine as a special geographical
area, due to resource development and the cumulative affects
of ongoing, facing a serious ecological damage to the
environment. Which mine land resources and the evolution
triggered by a series of negative effects is the most serious
problem impact of the mining area of sustainable development.
Shenyang mine district need to reduce the coal mining
subsidence and make land rectification for subsidence areas.
