Abstract
Based on the land use data of 2000, 2010 and 2020, using GIS technology along with landscape ecology methods, this paper monitored the changes in land use and landscape pattern in Wuhan. The findings are as follows: (1) the main features of land use change in Wuhan were the expansion of urban area and the decline of cropland, forest, wetland and water in recent 20 years; (2) forest, wetland and water kept a transfer-out trend while urban kept a transfer-in trend; (3) the fragmentation degree of forest, grassland and urban landscapes decreased from 2000 to 2020; (4) the patch shapes of almost all landscapes tended to be more regular under the human interventions. It is thereby worth reducing the interference intensity of human activities on landscape pattern in the process of urban growth.
Highlights
Land use and cover change (LUCC) depicts the spatial pattern of the earth's surface, and reflects the interaction between natural processes and human society, as well as serves as an important part of global environmental change and sustainable development [1,2,3]
All the landscape metrics were calculated by the FRAGSTATS (v4.2.1) software
In addition to transfer into urban area, 124.10 km2 of forest has been transferred out to cropland, which leads to the further reduction of forest area
Summary
Land use and cover change (LUCC) depicts the spatial pattern of the earth's surface, and reflects the interaction between natural processes and human society, as well as serves as an important part of global environmental change and sustainable development [1,2,3]. Previous researches suggest that with the in-depth development of the urbanization process, significant changes have taken place in land use and landscape pattern in many places around the world [4,5]. It is of great importance to analyze the changes of land use and landscape pattern, and preferably, to provide decisionmaking reference for urban planning strategies and policies. Since GlobeLand were separated into different tiles, the land use images containing Wuhan area were acquired.
