Exploration of Land-Use Change and Drivers In Qixia City Based on Multi-Temporal Landsat8 Remote Sensing Image

Abstract

The research results on land use and cover change (LUCC) are constantly updated, which is of great significance to correctly handle the relationship between human activities and ecological environment. In this article, Landsat8 remote sensing images, DEM data and statistical yearbook data of Qixia city in Shandong province are selected in 2013, 2018 and 2021 to explore the changes in this city’s land use. Through supervised classification, land use dynamic degree (LUDD) and land use transfer matrix, LUCC has been analyzed, and through the CORREL and DEM slope analysis, the main driving force has been investigated. The results indicate that the area of orchards in Qixia city is showing an increasing trend and the area of farmland, water and residential land shows a decreasing trend. Single land use dynamic degree of industrial land is the largest. The main driving forces of the industrial land and the orchard area are the social economic factors, which are mainly manifested as the influence of the regional GDP, the gross product of primary and tertiary sectors as well as the gross value of agricultural produce. In addition, the population is what is causing changes in the amount of farmland and residential land, and the terrain slope also impact on the variation of land-use classification significantly.
