Mu Us sandland with dry climate

scarce water

and fragile ecological environment

is very sensitive to all kinds of anthropogenic disturbances. Coal Mining resources in this region is bound to increase the burden on local environment

and make the ecological environment worse. Taking Dabaodang coal mine as an example

the number of patches

shape index

diversity index and other indicators were analyzed through field investigation

to find out the type and distribution of natural vegetation

using geographic information system technology and surface subsidence prediction model

and vegetation landscape pattern change caused by coal mining was predicted. The results showed that after coal mining

the landscape fragmentation increased

patch shape was complexitied

the landscape heterogeneity decreased

and the vegetation biomass reduced. The vegetation types changed. Bushes originally had Sabina vulgaris

Salix psammophila

Astragalus adsurgens as the dominant species of succeed to shrubs which was dominated by species Artemisia ordosica. From the change of whole mining area

there are some disturbance of coal mining to the natural ecological system

but was not cause the radical change

the natural ecological system still had certain recovery and control ability. A series of biological and engineering measures should be taken to promote ecological environment of the mining area to the direction of sustainable development.
