摘　　要：将土地利用模型(RFFLUS)、生态系统服务功能模型(InVEST)和地理探测器模型(Geodetector)耦合,分析平朔大型露采矿区1985—2025年土地利用变化,探索其生境质量的时空演变规律,并揭示影响生境质量的自然和人为因素。结果表明:(1)平朔矿区的主要土地利用类型为耕地、草地和建设用地;1985—2025年建设用地、草地面积增加,耕地大面积减少,耕地主要转为林地和草地,林地和水域减少较小。(2)生境质量等级分布与土地利用分布具有一致性,高质量生境主要分布于林地,低质量生境分布于建设用地;1985—2015年生境质量总体略有下降,煤矿开采是生境质量下降的主要原因;2025年仍存在生境下降风险,需要坚持生态复垦。(3)影响生境质量变化的主导影响因子是NDVI,其次为煤炭生产能力和GDP;在交互作用探测中,因子之间的交互作用均为增强,其中NDVI与GDP的交互作用最大。Assessment and prediction of habitat quality caused by land use change are of great significance for ecological restoration and sustainable development of mining areas.In this paper,the land use model(RFFLUS),ecosystem service function model(InVEST)and geographic detector model(Geodetector)were coupled to analyze the land use change in Pingshuo open pit mining area from 1985 to 2025.The coupled model was used to explore the spatial-temporal evolution of habitat quality during that period and to reveal the natural and human factors affecting habitat quality.The results showed that:(1)The main types of land use of Pingshuo mining area were cultivated land,grassland and construction land.The construction land and grassland areas increased from 1985 to 2025 and the cultivated land area decreased significantly.The cultivated land was mainly changed to forest land and grassland and the decrease of forest land and water area was little.(2)The distribution of habitat quality grade is consistent with the distribution of land use.High quality habitat is mainly distributed in forest land and low quality habitat is distributed in construction land.The overall habitat quality declined slightly from 1985 to 2015.Coal mining was the main reason for the decline of habitat quality.There was still a risk of habitat decline in 2025 and persisting ecological reclamation is needed to avoid this situation.(3)Factor detection found that NDVI was the dominant factor affecting the change of habitat quality,followed by coal production capacity and GDP.In the interaction detection,the interaction between factors was enhanced and the interaction between NDVI and GDP was the largest.A scientific basis for the implementation of ecological protection and land use planning in mining areas is provided in this paper.
