Abstract

The study explored the ecological damage in central-western China due to energy shift and coal mining's soil impact, aiming to offer theoretical and practical support for regional ecological protection and sustainable development. This paper took the Ehuobulake Coal Mine Area in Xinjiang as the research area. The orthogonal matrix factor analysis method and the common factor analysis method were jointly used to conduct a source apportionment study of heavy metals, and spatial representation was carried out in combination with geographic information technology. (1) The moisture content in the research area was in a state of strong variation, decreasing successively from Area T (26.30%), Area L (8.96%), Area B (3.43%) to Area N (3.42%). The pH was in a state of weak variation, gradually decreasing from Area N (8.43), Area B (8.14), Area T (8.06) to Area L (7.83). (2) Based on the Positive Matrix Factorization (PMF), factor 1, factor 2, factor 3 and factor 4 were judged to be transportation sources, coal mining sources, parent material sources and mixed sources respectively. Through factor analysis, factor 1, factor 2, factor 3 and factor 4 were judged to be parent material sources, transportation sources, coal mining and transportation sources and mixed sources respectively. The orthogonal matrix factor analysis method and the common factor analysis method had the same number of source factors. The qualitative interpretations of the factors were basically consistent, and the accuracy of the analysis results was high. The analysis results can provide theoretical support for the tracing of pollutants.

煤矿开采对土壤理化性质的影响及土壤重金属源分析

本研究探讨了能源转移和煤炭开采对中西部生态环境的影响，旨在为区域生态保护和可持续发展提供理论和实践支持。本文以新疆鄂火布拉克矿区为研究区。采用正交矩阵因子分析法和公因子分析法联合进行重金属来源解析研究，并结合地理信息技术进行空间表征。(1)研究区水分含量呈强烈变化状态，从T区（26.30%）、L区（8.96%）、B区（3.43%）到N区（3.42%）依次递减。从N区（8.43）、B区（8.14）、T区（8.06）到L区（7.83），pH呈弱变化状态。(2)基于正矩阵分解（PMF），将因子1、因子2、因子3和因子4分别判断为运输源、采煤源、母质源和混合源。通过因子分析，判断因子1、因子2、因子3、因子4分别为母质源、运输源、采运源和混合源。正交矩阵因子分析法与普通因子分析法的源因子数量相同。各因子的定性解释基本一致，分析结果的准确度较高。分析结果可为污染物溯源提供理论支持。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
