Spatial and temporal evolution of landscape pattern in downtown area of Jixi City, China

Abstract

ABSTRACT Based on the technology of RS & GIS and the remote sensing images of Jixi City in 1993, 2003 and 2015, this study analyzes quantitatively the temporal and spatial evolution characters of landscape pattern in the downtown area of Jixi City in China in the past 22 years. The research results show that the area of mine land, farmland and construction land increased greatly from 1993 to 2015. As an important part of the urban natural ecosystem, the area of water area, forest and grassland are also decreasing year by year. In the past 22 years, due to the impact of human activities such as coal resources development, the coal mine land in the central urban area is distributed in the agricultural farming area and the edge zone with different landscape types. On the whole, the fragmentation degree and diversity of regional landscape are increasing, and human activities have a significant impact on the urban landscape pattern of Jixi City. This paper attempts to explore the general law of landscape pattern change under the influence of human activities in mining cities and to provide a reference for urban land use planning and scientific decision-making of relevant government departments.
