摘　　要：霍东矿区属于国家规划矿区,面临着采矿等人类活动与生态保护的矛盾,研究矿区生态系统服务对其生态安全格局有重要作用。本文以霍东矿区为研究对象,分析其2000—2020年土地利用变化情况,采用当量因子法估算生态系统服务价值(ESV)并修正,应用地理探测器进一步探究ESV的空间驱动因素。结果表明:(1)霍东矿区主要土地利用类型为林地和草地,21年间霍东矿区土地利用活跃程度不高,草地面积减少;(2)21年间霍东矿区ESV呈上升趋势,共增长2900万元,空间格局变化不大,整体北高南低,高价值区及热点区域主要分布在矿区西北部及中部林地,中等价值区环绕较高价值区分布,低价值区呈“一面多带”分布格局,和冷点区域集中分布在矿区西南部与沁河及其支流两岸耕地和草地区域;(3)地理探测器结果表明自然因素主导影响霍东矿区ESV,土地利用程度解释力最大,因子贡献率达到0.5以上,高程、坡度、气温以及土壤侵蚀的因子贡献率均达到0.25以上,主要因子交互作用类型为双因子增强,人类活动增强了自然因素对生态系统服务的影响。研究结果可为霍东矿区生态保护与土地利用提供参考。The Huodong mining area is a national planning mining area and faces the contradiction between human activities such as mining and ecological protection,so study on the ecosystem services of mining areas is important for protecting its eco-security pattern.Based on land use data from 2000 to 2020,we analyzed the land use changes in Huodong mining area,estimated the ecosystem service value(ESV)of the Huodong mining area using the equivalent factor method,and used geographic detectors to further explore the drivers of ecosystem service value.The results show that:(1)The main types land use in Huodong mining area are forest and grassland,the dynamic degree of land use in Huodong mining area is not high during the 21 years,the area of grassland has decreased.(2)The ecological service value of the Huodong mining area increased by 29 million yuan from 2000 to 2020,showing a relatively stable spatial pattern characterized by high in the north and low in the south.The high-value areas and hotspot areas are mainly distributed in the northwestern and central forests of mining area.The medium-value areas are distributed around the highvalue areas.The low-value areas and cold spots are concentrated in the southwest of the mining area and on both sides of the Qinhe River and its tributaries,mainly consisting of cultivated land and grassland,presenting a distribution pattern of"one cluster and multiple stripes";(3)Geographic detectors shows that natural factors dominate the impact of ESV at the Hodong mining area,and the degree of land use has the most significant effect on the value of ecological services in the Huodong mining area,with factor contribution rates of more than 0.5.The contribution rates of elevation,slope,temperature and soil erosion all reach 0.25 or higher.Most of the factors enhanced each other,with human activities enhancing the influence of natural factors on ecosystem services.The results provide a reference for ecosystem conservation and land resource utilization in Huodong mining area.
