- Abstract:

The research on land use and landscape change can enhance the understanding of the nature and human activities on the society, economy and ecology. Jianghuai Ecological Economic Zone(JHEEZ), a key functional economic zone of ‘1+3' in Jiangsu Province, plays a unique role in the future development of Jiangsu Province. Therefore, it is important to study the changes of land use and landscape pattern in JHEEZ. In this research, we used the remote sensing images of 2000, 2005, 2010 and 2015 in JHEEZ as the data sources. With the support of multiple tools including ArcGIS and Fragstats software, land use transfer matrix, landscape pattern analysis, gradient zone analysis were employed to reveal the changes of land use and landscape pattern in the JHEEZ. The dominant land types in JHEEZ included cropland, construction land, and water area. From 2000 to 2015, the cropland area and water area decreased by 2 366.45 km2 and 198.45 km2, respectively, while the construction land area increased by 2 271.29 km2. Cropland, construction land, and water area increased first and then decreased with the fragmentation degree of gradient zone. The shape of cultivated land and construction land exhibited a simple shape of gradient zone, while water area tended to be complex. In general, the center area in JHEEZ exhibited an obvious agglomeration while the fringe area exhibited a high fragmentation degree. These results suggest that urbanization, rapid economic development, and the policy of returning cultivated land to lake are the principal factors on the land use changes. Protecting basic farmland, controlling the scale of urban expansion, and restoring water resources are important measures to ensure the sustainable development and maintain healthy ecosystem in JHEEZ.
