北部湾经济区土地利用变化及其驱动力研究

Research of Land Use Change and its Driving Force in Guangxi Beibu Gulf Economic Zone

通过对北部湾经济区1990、2000、2010年的遥感影像图进行监督分类,得出三个年份的土地利用现状图,在此基础上分析了1990-2000年和2000～2010年两个期间内的土地利用结构数量变化、土地利用转移矩阵和土地利用区域变化差异情况,对影响北部湾经济区土地利用变化的驱动力进行分析,得出影响北部湾土地利用变化的主要驱动因素有自然因素驱动力和社会经济因素驱动力两个方面,其中自然因素驱动力包括气候、地形地貌和土壤;社会经济因素驱动力包括经济因素、人口因素、城市化水平、政策因素。

Through the supervision and classification of remote sensing image drawing of 1990,2000,2010 years in the beibu gulf economic zone,the three-year land use maps were obtained,On above basis,the number change of land use structure,land use transition matrix,regional difference of land use changes were analyzed in 1990-2000 and 2000-2011,and driving force of Beibu Gulf Economic Zone land use change was analyzed,the main driving factors of land use change in the Beibu Gulf were obtained,that is natural factors driving force and the socio-economic factors driving force,natural factors driving force included climate,topography and soil;Social economic factors driving force included the economic factors,population factors,the urbanization level,policy factors.
