Based on RS and GIS techniques, and combining with digital terrain index and land use degree composite index, this paper studied the changes of land use pattern in Qixia City of Shandong Province form 1987 to 2003, and quantitatively analyzed the land use degree on terrain gradient. The results indicated that in the City, construction land had obvious advantageous on lower terrain niche, the advantageous terrain niche section of orchard increased by six terrain niche and distributed from aggregation to uniformity, while the advantageous terrain niche of crop land, forest land, grass land, water area, and unutilized land generally remained stable during the study period. According to the quantitative expression of land use degree on terrain gradient, terrain niche was divided into three sections, i.e., 1-15, 16-30, and 31-50, which occupied 49.48%, 43.58%, and 6.94% of the total study area, respectively.
基于遥感(RS)和地理信息系统(GIS)技术,并结合数字地形指数和土地利用程度综合指数,本文研究了山东省栖霞市1987年至2003年土地利用格局的变化,并对地形梯度上的土地利用程度进行了定量分析。结果表明,在该市,建设用地在较低地形位具有明显优势,果园的优势地形位区间增加了6个地形位,且分布由聚集趋于均匀,而耕地、林地、草地、水域和未利用地的优势地形位在研究期间总体保持稳定。根据地形梯度上土地利用程度的定量表达,将地形位划分为三个区间,即1 - 15、16 - 30和31 - 50,分别占研究总面积的49.48%、43.58%和6.94%。
