摘要
以徐州九里矿区1995,2000,2004,2010年的Landsat TM影像为数据源,采用大气校正法反演地表温度,研究矿区生态扰动对地表温度的影响效应。研究表明,1995～2010年徐州九里矿区工矿用地减少、生态用地增加,2010年异常高温区和高温区比1995年减少109.7公顷和181.28公顷,正常温度区和低值温度区比1995年增加234.14公顷和59.52公顷;不同土地利用类型对地表温度影响的差异性显著,地表温度总体表现为:工矿建设用地>工矿废弃地>耕地>林地>水域;植被指数与地表温度呈现明显的负相关性,2010年矿区植被覆盖度比1995年增加了2.7%,平均温度比1995年降低了1.24℃;土壤结构破坏、土壤污染等其他生态扰动对矿区地表温度变化同样具有明显作用。
Taking Landsat TM images in 1995,2000,2004, 2010 in Jiuli coal mine area in Xuzhou as the source data, the inversion of surface temperature in the mining area was made by atmospheric correction method, and the effect of ecologi- cal disturbance on the surface temperature was studied. The studies showed that from 1995 to 2010, in the mining area the area of industrial land reduced and the area of ecological land increased, the areas with abnormal high temperature and high temperature reduced 109.7 hectares and 181. 28 hec- tares, the areas with normal temperature and low tempera- ture increased 234.14 hectares and 59.52 hectares in 2010. There were significant differences in the influence of land use types on surface temperature, the surface temperature overallperformance as ： industrial construction land〉 mining waste land〉 cultivated land 〉 woodland 〉 water area. Vegetation index and surface temperature have significantly negative correlation. The area of vegetation coverage in the mining ar- ea in 2010 increased 2.7% than that in 1995, and the surface average temperature was 1.24C lower than 1995. The dam- age of soil structure, soil pollution and other ecological dis- turbance also had an obvious effect on surface temperature.
