In order to constructe the eco-environment of Luan mine land system scitifically

the variances of natural and environmental factor sand artificial factors such as industry and mining production are analyzed and the mine land eco-environment pressure evaluation index system is established. Eco-env ironmental pressure of Luan mine land is divided into four types

e. g.

natura-l resources pressure A1

resource consumption pressure A2

environmental pollution pressure A3

and production scale pressure A4. Results show that the total eco-environmental pressure of Luan mine land system belongs to the moderate pressure and sub-pressures followed a descending order of resource consumption pressure A2

environmental pollution pressure A3

production scale pressure A4

and natura-l resources pressure A1. Because of different units of land system under different eco-environmental pressures

this may show different land ecological functions. Ther efore

the land system can be divided into production land type

protection land type

consumption land type

and mixed land type

according to the eco-environmental characteristics. Luan mine land is divided into eleven types of ecological function zones and the four regions of earth and rock slope consumption area

subsidence and wet land protect ion area

mine-industry eco-economic area

and Hirakawa arable land production area. Its area ratios are 6.50%

19.16%

8.77%

and 65.57%

respectively. The production land and consumption land are oversized and the mixed land and the protect ion area are very small

which indicates that there is an unreasonable use in Luan mine land system. Based on above analysis and Luan mine actual situation

the corresponding countermeasures of mine land system were proposed for eco-environmental protection and mult-i dimensional ecology economical system.
