    草原区煤电基地的大规模开发必然引发剧烈的生态环境问题。针对胜利煤电基地生态系统的特点,应用系统分析方法,以土地、水体和大气为空间载体,辨识生态扰动因子,构建生态环境综合评价指标体系,以多源动态监测技术为获取基础信息的主要手段,利用遥感反演、数据融合、空间插值、统计分析等数据处理方法,从煤电基地尺度、功能区单元和最适宜格网单元等多时空尺度,综合评价和分析研究区域2000年,2005年,2010年和2015年的生态环境状况,探寻区域生态的时空变化规律。研究表明,2000—2015年,研究区域生态环境整体处于良好状态;2005—2010年,煤电基地开发规模迅速扩大,恶化趋势明显,生态环境状况显著变差、明显变差和略微变差的区域面积分别达到512.76,664.52,284.26km2市城区、城镇居民点和省道S307两侧区域,并以露天矿区及电厂区、市区和居民点为中心形成阶梯状缓冲区,印证了露天矿开采及电厂开发、城市建设对生态环境产生负面扰动的累积效应;2010—2015年,露天矿区排土场复垦、电厂控排、城市湿地公园建设及省道S307沿线绿化有效改善了局部生态环境状况,体现了生态修复与监管对生态环境恢复的重要性。根据生态环境评价结果及其时空发展规律,提出了搭建基于大数据的草原区煤电基地生态环境“监测-评价-管理”三位一体多源动态监测平台和建立生态环境修复“5W+2H+E”循环管理模式的管控对策,为煤电基地环境保护和生态修复监管提供了可靠依据。

  • Abstract

    The large-scale development of prairie coal-electricity base generates a host of severe eco-environmental problems. Taking into account the characteristics of the ecosystem around the Shengli coal-electricity base,this study applied a system analysis method. Land,water,and the atmosphere were used as spatial carriers to identify ecological disturbance factors and to construct a comprehensive evaluation index system of the eco-environment. In addition,this study used multi-source dynamic monitoring technology as the main mean to obtain basic information. Remote sensing inversion,data fusion,spatial interpolation,and statistical analysis along with other data processing methods were used to comprehensively evaluate and analyze the eco-environment of the region in 2000,2005,2010 and 2015. This analy- sis was also used to explore the temporal and spatial change laws of the regional ecology,stemming from the multi-tem- poral and spatial scales such as the coal-electricity base,the functional area unit,and the most suitable grid unit. The results show that the overall eco-environment of the study area was in a good state from 2000 to 2015. From 2005 to 2010,the development scale of the coal-electricity base expanded rapidly,resulting in an obvious deterioration trend. The ecological areas that incurred significant deterioration, moderate deterioration and slight deterioration reached 512. 76,664. 52 and 284. 26 km2 ,respectively,accounting for 72. 23% of the study area. The deterioration was mainly concentrated in the open-pit mining area,power station area,urban area of Xilinhat City,urban settlements and the bi- lateral area of provincial highway S307. Moreover,a ladder buffer zone was formed within the areas around the open-pit mining and power station,and the urban and residential zones served as the center. This confirmed the cumulative effect of the negative disturbances to the eco-environment caused by open-pit mining,power station development and urban construction. From 2010 to 2015,the reclamation of the dump in the open-pit mining area,the controlled dis- charge of the power station,the construction of an urban wetland park and the greening along provincial highway S307 have effectively improved the local ecological environment. It reflected the importance of ecological restoration and reg- ulation to eco-environment restoration. According to the results of eco-environment evaluation and its spatial-temporal development laws,the paper puts forward a multi-source dynamic monitoring platform with the trinity of “ monitoring, evaluation and management” based on big data for the eco-environment of prairie coal-electricity base and the control countermeasures for the establishment of the circular management mode of “5W+2H+E” for the eco-environment res- toration,providing a reliable basis for the environmental protection and ecological restoration supervision of the coal-e- lectricity base.
