摘　　要：我国大量土地因工业及采矿活动遭到破坏,而土地复垦率却相对较低,为了消除工矿废弃地对生态环境造成的不利影响,对工矿废弃地景观格局的分析显得尤为重要。本文以江苏省盱眙县工矿废弃地复垦后景观格局为研究对象,依据各复垦方向服务价值设定耕地、园地、林地和草地4种复垦情景,并根据地势、土壤质地等因素将盱眙县划分为西南和北部两个区域,采用Fragstats软件计算不同情景的景观格局指数并对其进行分析和对比,得出相对较优的盱眙县工矿废弃地复垦方向。结果表明,盱眙县工矿废弃地复垦景观格局多情景模拟结果为西南地区复垦方向为林地,北部地区复垦方向为耕地。上述研究过程可较好地应用于盱眙县工矿废弃地复垦利用方向研究,进而可为类似区域工矿废弃地的可持续利用和生态环境保护提供决策参考。A large amount of land in China has been destroyed due to industrial and mining activities, but the rate of land reclamation is relatively low. In order to eliminate the negative impact of desert land of industrial mining area on the ecological environment, it is particularly important to analyze the landscape pattern of industrial and mining abandoned land. This paper takes the landscape pattern of desert land of industrial mining area in Xuyi County, Jiangsu Province as the research object. According to the service value of each reclamation direction, four reclamation scenarios are set for cultivated land, garden land, woodland and grassland, and Xuyi is determined according to factors such as topography and soil texture. The county is divided into two regions, the southwest and the north. Fragstats software is used to calculate the landscape pattern index of different scenarios, analyze and compare them, and obtain a relatively better direction for the rehabilitation of desert land of industrial mining area in Xuyi County. The results show that the multi-scenario simulation results of the landscape pattern of desert land of industrial mining area reclamation in Xuyi County can conclude that the reclamation direction in the southwest is forest land and the reclamation direction in the north is cultivated land. The above research process can be better applied to the research on the reclamation and utilization of desert land of industrial mining area in Xuyi County, and can provide decision-making reference for the sustainable use of desert land of industrial mining area and ecological environment protection in similar areas.
