【摘要】 土地利用变化研究是认知区域人地关系状况的有效途径之一。基于1985年、2000年、2015年3个时相的遥感数据,利用景观生态学理论及空间分析方法定量刻画长春市土地利用及其生态系统服务价值演变,并探讨两者间的响应情况。结果表明:①长春市土地利用结构变化显著,其中建设用地面积持续增加,耕地面积减少;土地转移变化中耕地与建设用地、耕地与林地间的转移分别居于主要地位和次要地位。②长春市单一土地利用动态度中未利用地动态变化最显著,耕地变化较缓慢。③长春市生态系统服务价值呈下降趋势,林地、耕地与水域三种类型构成了长春市生态系统服务价值的主体;生态服务价值空间聚集趋势日益显著,冷热点格局相对稳定。更多还原

【Abstract】 Research on the change of land use was one of the effective ways to cognize regional human-land relationship. Based on the remote sensing data of three phases in 1985,2000 and 2015,the theory of landscape ecology and spatial analysis method were used to quantitatively depict the evolution of land use and ecosystem service value( ESV) in Changchun City,and the response between them was discussed. The results showed that: ①The land use structure of Changchun changed significantly,in which the area of construction land continued to increase while the area of cultivated land decreased. In the change of land transfer,the transfer between cultivated land and construction land and the transfer between cultivated land and forest land occupied the primary and secondary position respectively. ②In the dynamic degree of single land use in Changchun,the dynamic change of unused land was the most significant,and the change of cultivated land was relatively slow. ③The ESV in Changchun declined,and the three types of forest land,cultivated land and water area constituted the main body of the ESV in Changchun. The spatial aggregation trend of ESV was increasingly obvious and the pattern of cold and hot spots was relatively stable.更多还原
