摘要:

为探索整个松辽流域片区1990—2015年的土地利用时空变化特征及驱动机制,通过ArcGIS空间分析、土地利用转移矩阵、SPSS相关分析和因子分析等方法,分析社会经济统计数据和气候数据。结果表明,松辽流域1990—2015年的土地利用变化差异显著。土地类型占地面积为林地>耕地>草地>未利用土地>水域>城乡建设用地,土地变化面积为耕地>草地>林地>未利用土地>水域>城乡建设用地。1990—2000年耕地、林地、草地和未利用土地相互转化明显,建设用地迅速扩张。乔木林、高覆盖草地分别减少了1.26万、1.74万km2,旱地增加了2.25万km2。松辽流域片区的土地利用变化主要驱动因子是经济发展和人口增长。本研究从流域片区尺度上为松辽流域片区的土地资源管理和规划提供理论参考。

Abstract:

To explain the spatial and temporal change characteristic and driving mechanism of land-use in Songliao River Basin from 1990 to 2015, the authors used ArcGIS space analysis, land-use type transfer matrix and SPSS correlation analysis and factor analysis, analyzed the change of land-use with the statistics of social economic and climate. The results showed that the land-use types in the Songliao River Basin changed significantly from 1990 to 2015. The land-use area followed the order of woodland> cultivated land> grassland> unused land> water area> urban and rural construction land, and the change of land-use area followed the order of cultivated land> grassland> woodland> unused land> water area> urban and rural construction land. The mutual transformation was obvious between cultivated land, woodland, grassland and unused land in 1990 to 2000, the construction land was expanding rapidly. The woodland and high-coverage grassland decreased by 12.6 and 17.4 thousand km2 respectively, but the dry land increased by 22.5 thousand km2. The main driving factors of land-use change were economic development and population growth. This study quantified the driving factors on the foundation of basin area, which could provide theoretical guidance for land-use resource management and formulation of ecological restoration plans.

Key words: Songliao River Basin, land-use change, driving factor, land-use type transfer matrix, principal component analysis
