摘要
采用Landsat多期遥感卫星影像与单位面积当量因子法,对黄土高原典型矿区——轩岗矿区1986—2015年生态系统服务价值变化进行研究。结果表明:轩岗矿区生态系统服务价值从1986年的22.18亿元减少到2015年的16.86亿元;2006年是轩岗矿区生态系统服务价值变化的重要节点,变化斜率由2006年之前的-0.02变为之后的-0.52,生态系统服务价值减小速率加快;煤矿开采对土地利用的扰动是生态服务价值变化的主要原因,研究期内工矿用地、城镇和居民点用地持续增加,耕地、草地面积显著减少;轩岗矿区不同类型生态系统的服务价值敏感度指数均小于1,最大值为0.55,这说明生态服务价值对单位面积生态系统服务价值参数不敏感。煤矿开采对于生态脆弱区生态服务价值具有负面影响,且随着煤矿开采活动的持续推进而呈加剧态势,亟须采取有效措施遏制矿区生态服务价值流失。
Based on the Landsat TM/OLI remotely sensed data and per unit area method, the ecosystem service values from 1986 to 2015 in Xuangang mining area were analyzed. Results show that the ecosystem service values in the mining area decreased from 2. 218 billion yuan in 2000 to 1. 668 billion yuan in 2015. The ecosystem service values sharply decreased after 2006, and the slopes of ecosystem service values in the mining area were -0.02 and -0.52, before and after 2006, respectively. The disturbance of coal mining to land use was the main reason for the change of ecological service values. During the study period, the land use of industrial and mining land, urban and rural settlements increased continuously, and cultivated land and grassland decreased significantly. The CS (coefficient sensitivity) of ecosystem service values in Xuangang mining area is less than 1, and the maximum is 0.55. The negative influence of coal mining service values in ecological sensitive district is getting worse. The local government effective measures to curb the loss of ecological service value in the mining areas.
