In this paper, we use regression analysis of multivariate linear

Use each type of factor and cultivated areas for stepwise 
regression analysis, to determine the coefficient of such factors

factors. Process to take into account various indicators

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

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.
