Research on Spatio-temporal Variation of Land Ecological Security in the Huaihe River Ecological and Economic Circle
摘要
Abstract
The DPSIR method is used to study the regional scale and spatial scale of the Huaihe River area,and the land-space and time-space pattern of the Huaihe River eco-economic circle from 2009 to 2021 were ana-lyzed using the TOPSIS method.The findings indicate that:(1)The level of ecological security of land was im-proved from 0.268 3 in 2009 to 0.335 4 in 2021,the soil environmental quality in this area has increased from a less secure level to a critical level,and the drivers,states,pressures,impacts,and response sub-systems were in an upward trend,level of ecological security of land generally demonstrates an improving trend;(2)The ecological security of the land in the study region gradually increased during 2009-2013,2013-2015 leveled off,2015-2016 declined,and 2016-2021 increased year by year;(3)By 2021,the overall land ecological security level of the 25 municipalities in the study area is projected to increase by 1 level compared to 2009,and the characteristics of spa-tial differentiation levels are significant,it presents a overall spatial differentiation of'Shandong 4 cities>Jiangsu 7 cities>Henan 6 cities>Anhui 8 cities'.关键词
