Цель. Проанализировать изменения характера землепользования в г. Манди Бахоуддин (Пенджаб, Пакистан) в период активной градостроительной трансформации с 1996 по 2016 гг. Процедура и методы. Изучены пространственно-временные аспекты изменения землепользования в г. Манди Бахауддин, Пенджаб, Пакистан. Для исследования использованы многозональные спутниковые снимки Landsat TM, ETM+ и OLI/TIRS за 1990, 2000 и 2016 гг. Космоснимки получены с помощью ресурсов Global Land Cover Facility (GLCF) и Earth Explorer. При создании растровых композитов использованы все каналы, дешифрирование проведено с помощью метода контролируемой классификации с использованием ERDAS Imagine 10.2. Выделены три класса объектов: сельскохозяйственные земли, пустоши и застроенная территория. Результаты. Проведённый анализ показал, что площадь застройки и пустошей увеличились на 30 и 58% соответственно, а сельскохозяйственные земли сократились на 88%. Теоретическая и практическая значимость. Обобщён материал по исследованной теме. Изменение землепользования (land use/land cover) связано не только с изменением окружающей среды, но и социума, и представляет существенный теоретический и практический интерес. В первую очередь это относится к развивающимся странам, таким, как Пакистан. В качестве объекта исследования выбран г. Манди Бахауддин, отличающийся стремительным ростом населения. Результаты работы показали изменения в характере землепользования и переход от сельского хозяйства к городской застройке. Показано ведущее значение урбанизации в смене характера землепользования.

Аim. We analyze land use/land cover in the city of Mandi Bahauddin, Punjab, Pakistan in the period from 1996 to 2016. Methodology. Spatiotemporal aspects of land-use/land-cover changes in the city of Mandi Bahauddin are analyzed. Landsat satellite imageries of 3 different periods (1990, 2000 and 2016) are obtained from the Global Land Cover Facility site (GLCF) and Earth Explorer site to compute the changes in the land use and land cover (LULC) from 1990 to 2016. To classify different categories, a false-color composite is prepared by combining all bands of downloaded images. The false-color composite is prepared through layer stacking, and supervised classification is used to determine a change in residential land use in Mandi Bahauddin by ERDAS Imagine 10.2. The imageries of the area under study are categorized into three classes: agriculture land, barren land and built-up area. Results. The results of this study indicate that the size of the built-up area and barren land increased by 30% and 58%, respectively, and the size of the agricultural land decreased by 88%. Research implications. The land-use/land-cover changes have a great theoretical and practice interest for sustainability of environment and society. It is found that changes are mainly detected in the Mandi Bahauddin city where the population has rapidly increased. The results of investigation have demonstrated the land-use/land-cover changes and shifts from agriculture land to urban settlement. Urbanization is the major cause of land use change in the period from 1996 to 2016 according to the results of the study.
