摘要

研究石油地下利用基础设施发达地区自然复合体的改造,是解决油区环境问题的前提条件。Tengiz油田位于哈萨克斯坦西部的阿特劳地区,是世界上最大的油田之一。该领域已经进行了超过40年的密集开发,其特点是大量的人为负荷,这有助于景观综合体的重大转变。本研究的目的是调查腾吉兹地区的景观变化动态,并对其生态状况进行评价。在多年研究资料的基础上,确定了天吉兹地区的特征和影响该景观综合体的主要技术成因。根据卫星图像计算了几个表征人为负荷的定量指标。基于Landsat - 5 TM、7 ETM+和8 OLI和Sentinel-2A (S2A)数据,利用归一化植被指数(NDVI)计算了1990 - 2020年土地覆盖植被指数,揭示了景观变化的动态特征。结果表明,部分景观成分的面积持续恶化。例如,由于工业设施撤出,2020年露天土壤面积减少,而由于集约化开发,到2020年露天土壤面积增加了2.2倍。研究结果表明,在人为活动影响下,监测和研究荒漠景观复合体对于确保土地的可持续发展具有重要意义。

Impact of the Tengiz Oil Field on the State of Land Cover
Abstract The study of the transformation of natural complexes in areas with a developed infrastructure for oil subsurface use is a prerequisite condition for solving the environmental problems of oil-producing regions. Located in the territory of the Atyrau Region in Western Kazakhstan, the Tengiz oil field is one of the largest oil fields in the world. The field has been under intensive development for more than 40 years and is characterised by a large volume of anthropogenic load, which contributes to a significant transformation of the landscape complex. The purpose of this study is to investigate the dynamics of landscape changes in the territory of the Tengiz field and to assess its ecological condition. Based on the materials from many years of research, the features of the Tengiz field and the main technogenic sources affecting the landscape complex were identified. Several quantitative indicators characterising the anthropogenic load were calculated based on satellite images. On the basis of Landsat – 5 TM, 7 ETM+ and 8 OLI and Sentinel-2A (S2A) data, the vegetation index of land cover was calculated using normalised difference vegetation index (NDVI), demonstrating the dynamics of landscape changes in the period from 1990 to 2020. The obtained results show that the areas of some landscape components continue to deteriorate. For example, the area of open soil in 2020 decreased due to the withdrawal of these areas for industrial facilities, which increased by 2.2 times by 2020 due to intensive field development. This study demonstrates the importance of monitoring and studying desert landscape complexes under active anthropogenic impact to ensure the sustainable development of territories.

期刊介绍: Quaestiones Geographicae was established in 1974 as an annual journal of the Institute of Geography, Adam Mickiewicz University, Poznań, Poland. Its founder and first editor was Professor Stefan Kozarski. Initially the scope of the journal covered issues in both physical and socio-economic geography; since 1982, exclusively physical geography. In 2006 there appeared the idea of a return to the original conception of the journal, although in a somewhat modified organisational form. Quaestiones Geographicae publishes research results of wide interest in the following fields: •physical geography, •economic and human geography, •spatial management and planning,
