摘要: 采用遥感技术对矿区生态环境进行监测与评价,对矿区生态环境的保护和可持续发展具有重要意义。本文首先提出了一种遥感生态指数(RSEI)改进方案,除了采用原模型的绿度指标、湿度指标、热度指标及干度指标4个生态指标外,引入植被净初级生产力(NPP)指标,并对矿区生态环境进行各单生态指标评价分析,然后采用改进后的遥感生态指数,对神府矿区2000—2016年的生态环境变化进行综合评价。评价结果表明,2000—2016年,神府矿区的遥感生态指数呈整体升高趋势,RSEI增幅约为0.1/10 a,大部分区域植被生产力逐渐增强,生态环境得到恢复,生态环境质量逐渐提升。

Abstract: Monitoring and evaluating the ecological environment with the help of remote sensing technology is of great significance for the sustainable development of mining area. In this paper, an improved scheme of remote sensing ecological index (RSEI) is proposed. Based on the original model which contains four ecological indexes (NDVI, WET, LST, NDSI), the net primary productivity (NPP) of vegetation is introduced to characterize the ecosystem function of mining area. The ecological environment of the mining area is evaluated and analyzed by every single ecological index using the five ecological indexes. Using the improved remote sensing ecological index, the ecological environment changes of Shenfu mining area from 2000 to 2016 are evaluated. The evaluation results show that the remote sensing ecological index of Shenfu mining area shows an overall upward trend from 2000 to 2016 (0.1/10 a), and the vegetation productivity in most areas increases gradually, which means that the ecosystem function recovers gradually, and the ecological environment quality improves gradually.

Key words: RSEI, mining area, ecological environment, evaluation
