Research on long time series Normalized Difference Vegetation Index (NDVI) dynamic changes in mining areas is beneficial to clarify the impacts from global change and to reveal the influence of human activities on the mining area ecological environment. The long time series GIMMS AVHRR NDVI3g (1982-2013,32 a) global vegetation index and climate information (i. e.,precipitation and temperature) were selected as data sets. Data synthesis operation,linear regression and trend fitting contrasting the maximum NDVI, average NDVI and the total NDVI of directly affected areas,buffer areas (10 km and 20 km) and checked areas were used to calculate the change trends of the start,end and length of growing season. Three components in time,space and climate were implied using IDL programming language. Analysis of the sequential correlation results indicated that due to global warming,the mining area start of growing season (SOS) has been postponed 3 d,end of growing season (EOS) has advanced 30 d and length of growing season (LOS) has shorten 33 d -a reduction rate of 10.3 d/(10 a). With the increasing of mining years,the annual average of total NDVI declined during the 32 year research period,with a decline rate of 0.18/(10 a). Analysis of the spatial correlation indicated that the LOS in the buffer area (10 km and 20 km) and checked area (CK) have been extended, and the LOS in the mining area has been shortened. The LOS in mining area is 3 days shorter than that in the CK. The annual average NDVI over 32 years was 0.2936,0.2964, 0.3250 and 0.2918 for the mining area,the 10 km buffer area,the 20 km buffer area and the CK respectively. The relationships of different research districts were as follows: annual NDVI growth rate was followed by mining area (1.09%) < 10 km buffer area (2.16%) < 20 km buffer area (8.86%) < CK (9.87%). The annual NDVI growth rate in the mining area was lower than that in the CK. The total NDVI in the mining area began to decrease since 1995,while the total NDVI in non-mining area showed an increasing trend. This indicated that coal mining has had an obvious effect on regional ecological processes. The analysis of climate change correlation indicated that the NDVI is increasing with the increasing of temperature and decreasing of precipitation. The annual NDVI growth rate in natural ecological CK is higher than that in the mining area; the LOS in the CK showed a trend of extended with increasing of temperature and decreasing of precipitation,while the LOS in the mining area showed a shortening trend. The NDVI in the mining area, in addition to the interference by climate change,is also the result of mining activities. The results show that it is an indisputable fact that mining has a significant impact on regional ecological processes. (1) Human activities interfere with the evolution process of natural ecology over mining area. (2) Climate change has caused the NDVI to increase over the whole area. (3) Mining activities lead to decreasing NDVI in both mining and non-mining area. (4) The NDVI is influenced more seriously by mining activities than climate change.
