Abstract
In view of the shortcomings of the study on the evolution pattern of the current mining landscape pattern,this paper select eight indicators to analyze the landscape pattern characteristics of the study area.At first,We use FRAGSTATS to calculate the landscape pattern index,then analyze the change pattern of landscape pattern in the study area by comparing the classification data sets of the three periods in 2005 and 2015.The results show that,Study area on landscape pattern is the best granularity analysis for 20m;2005~2010,the mine development and expansion leads to increased cultivated land,grassland and woodland landscape patch fragmentation,the overall landscape pattern in mining area is the trend of fragmentation and complex;2010~2015,damaged arable land,grassland and woodland landscape has resumed due to the mining area ecological environment governance work carried out,area,the overall landscape pattern in mining area is the trend of rules and equalization.
