摘要/Abstract

摘要： 研究采矿扰动区内植被变化规律，能够为矿区生态修复提供理论依据。本文以山西省西山煤田为研究区，通过设立对比试验区，利用MODIS/NDVI（2001-2019年）结合同期的气温、降水气候因子，分别从植被指数的时空变化及与气象因子之间的关系等方面展开对比，用于探究采矿扰动区内植被变化情况。研究结果表明：①19年来西山煤田与间接影响区及校验区的植被均呈增加趋势，但西山煤田相比于校验区NDVI均值低11.42%。②西山煤田相较于自然生态条件下植被增长率为-5.53%。③西山煤田与校验区的NDVI值均受到气温、降水两种气象因子的影响，但是与降水的相关性更高，即受降水影响更大。

Abstract: The study of vegetation changes in mining disturbed areas can provide a theoretical basis for ecological restoration in mining areas. This paper takes the Xishan coalfield in Shanxi province as the research area, establishes a comparative experimental area, and uses MODIS/NDVI (2001-2019) to combine the temperature and precipitation climate factors of the same period to analyze the temporal and spatial changes of the vegetation index and the relationship with meteorological factors. The comparison is carried out to explore the vegetation changes in the areas disturbed by mining. The research results show that:① In the past 19 years, the vegetation in the Xishan coalfield, the indirect impact area and the verification area showed an increasing trend, but the average NDVI of the Xishan coalfield was 11.42% lower than that in the verification area. ② The growth rate of vegetation in Xishan coalfield is -5.53% compared with natural ecological conditions. ③ The NDVI values of the Xishan coalfield and the verification area are both affected by two climatic factors, temperature and precipitation, but the correlation with precipitation is higher, that is, it is more affected by precipitation.

Key words: mining disturbance, Xishan coalfield, comparative experiment area, MODIS/NDVI, climate driven
