针对科学定量化评价露天开采对土地扰动强度的难题，基于露天开采扰动效应理论，运用标准煤和生态足迹计算原理，提出了评价指标的公平转化准则和详细计算方法。结合露天矿全生命期采排工程时空发展规律，绘制了土地挖损强度(LEI)和土地压占强度(LOI)的变化曲线，划分了变化阶段，分析了各阶段的指标特征。以准格尔矿区露天矿为例进行了实证研究：受哈尔乌素露天矿开工建设的影响，2006—2010年LEI和LOI的年均增长率分别为56%和70.42%，土地生产力弹性系数LPR<1，负向土地扰动效应较强；2011年达产及生态重建以后，LEI和LOI的年均增长率分别为8%和2.8%，增速显著放缓，LPR>1且年均增长率为17.5%，至2015年底准格尔矿区土地生产力增加了近1倍，开采吨标准煤扰动的实际土地面积较2014年以前减小了35.9%，负向土地扰动效应正在逐渐减弱。研究结果表明：以土地挖损强度(LEI)、土地压占强度(LOI)和土地生产力弹性系数(LPR)等3个指标来量化露天开采对土地产生的扰动效应是符合实际的，但仅从露天开采对土地的挖损和压占角度分析露天矿对环境的破坏作用是不全面的，还应全面考虑土地复垦和生态重建对土地价值和环境功能的改善和提升作用。因此露天矿的决策是影响土地扰动强度的关键，对露天矿的科学规划和设计是减弱扰动效应的关键途径。

In view of the difficulty of scientific quantitative evaluation of land disturbance intensity of open-pit mining,the fair conversion criteria and detailed calculation methods of evaluation indicators were proposed based on the standard coal and ecological footprint calculation principles and the open-pit mining disturbance effect theory.Combined with the space-time development law of open-pit mine full-life mining and drainage engineering,the variation curves of Land Excavation Intensity(LEI) and Land Occupied Intensity(LOI) were drawn,the change phases were divided and the indicator characteristics of each stage were analyzed.An empirical study was carried out by taking the open-pit mine in the Jungar mining area as an example:affected by the construction of the Harwusu open-pit mine,the average annual growth rate of LEI and LOI were 56% and 70.42% respectively from 2006 to 2010,and the Land Productivity Resilience (LPR)<1,the negative land disturbance effect is stronger.After reaching production and ecological reconstruction in 2011,the average annual growth rate of LEI and LOI was 8% and 2.8% respectively,the growth rate slowed down significantly,LPR>1 with an average annual growth rate of 17.5%.By the end of 2015,the land productivity of the mining area has nearly doubled,and the actual land area disturbed by mining tons of standard coal has decreased by 35.9% compared with before 2014.The negative land disturbance effect was gradually weakening.The research results showed that it is practical to quantify the land disturbance intensity of open-pit mining with three indicators including Land Excavation Intensity(LEI),Land Occupied Intensity(LOI) and Land Productivity Resilience(LPR),but it is incomplete to analyze the damage of open pits to the environment from the perspective and land occupation of open-pit mining and it is also necessary to fully consider the role of land reclamation and ecological reconstruction in improving and enhancing land values and environmental functions.Therefore,the mining technology decision of open-pit mine is the key to affect the intensity of land disturbance intensity,and the scientific planning and design of open-pit mining technology is the key way to reduce the disturbance effect.
