摘要:
 以宝鸡市渭北旱塬区为研究对象,基于该区域2000、2005、2010年和2014年4期遥感影像,运用GIS技术和景观格局分析方法,系统分析区域土地利用与景观格局时空演变特征。结果表明,研究区景观基质为林地,面积占50%以上,耕地面积仅次于林地。土地利用情况变化显著,耕地面积明显减少,林地、草地、建设用地面积持续增长,土地利用转化过程以耕地转化为林地、草地和建设用地为主要特征。2000-2005年是土地利用动态变化幅度最大时段,后期土地利用动态变化速度相对减小。在研究时段内,景观的破碎化程度降低,景观趋向多样化和均衡化发展,但景观形状变得复杂,后期还需对土地利用进行合理调控。
Abstract:
 Aiming to provide a reference for the rational formulation of land use,this paper analyzed the changes of land use and landscape pattern systematically with the method of GIS and landscape pattern analysis in the arid-plain,north of Weihe River in Baoji,based on the remote sensing images of 2000,2005,2010 and 2014.The results showed that woodlands accounted for more than 50% was the matrix landscape in this area,the farmland was just inferior to the woodland.Land use structure changed significantly,farmland decreased obviously,while the forest land,grassland and built-up land continued to increase.The conversion of farmland into forest land,grassland and build-up land was the main features of land use conversion.From 2000 to 2005,the dynamic change of land use was the largest,and the dynamic change of land use in the later period was relatively reduced.During the research period,the degree of fragmentation of the landscape decreased,the landscape tended to be a diversified and balanced development,but the landscape shape became complicated.There needed more rational allocation direct at the land use of this area in the future.
