摘要:

选择黑龙江省鹤岗市作为研究区,基于其2000年、2010年和2020年这3期的Landsat遥感影像及DEM数据,采用Fragstats 4.0软件,利用Ann-CA-Markov耦合模型研究该市农林用地2000—2020年景观格局的变化,并对2030年景观格局进行模拟预测。结果表明:鹤岗市2000—2020年期间,耕地面积减少197.982 4km2,森林面积减少52.725 2 km2;模拟预测2030年土地利用情况,耕地面积预计增加1.036 8 km2,森林面积预计减少0.064 8 km2;并计算相关景观格局指数。鹤岗市农林用地破碎化程度较低,但受到外界干扰较强,应通过进一步优化调整景观格局,持续减少对生态环境影响,保障粮食及生态安全。

关键词: 景观格局, 模拟预测, 农林用地, 市域, 破碎化

Abstract:

Hegang City,Heilongjiang Province was selected as the research area.Based on its Landsat remote sensing images and DEM data in 2000,2010 and 2020,Fragstats 4.0 software was used,and the Ann-CA-Markov coupling model was utilized to study the changes in the landscape pattern of agricultural and forestry land in the city from 2000 to 2020,and simulated and predicted the landscape pattern in 2030.The results showed that from 2000 to 2020,the area of cultivated land in Hegang City decreased by 197.9824 km2,and the area of forest decreased by 52.7252 km2;the land use situation in 2030 was simulated and predicted,the area of cultivated land was expected to increase by 1.0368 km2,and the area of forest was expected to decrease by 0.0648 km2;and relevant pattern index was calculated.The degree of fragmentation of agricultural and forestry land in Hegang City was relatively low,but it was subject to strong external interference.Further optimization and adjustment of the landscape pattern should be carried out to continuously reduce the impact on the ecological environment and ensure food and ecological security.

Key words: landscape pattern, simulation forecast, agricultural and forestry land, urban area, fragmentation
