| 摘 要： | 在陕西省陇县土地利用数据和1∶5万地形图的基础上,利用ArcGIS 9.3软件和Spss17.0软件探讨不同海拔、坡度与坡向上土地利用类型的分布特征及土地利用的空间分布与地形因子的相关关系。结果表明:除林地、草地外,其他土地利用类型分布主要集中在海拔小于1300m、坡度小于15°的区域中;耕地在平地占优势地位,其他坡向级别中林地占最大比例,其次是耕地和草地,其他土地利用类型分布较少。耕地、林地、居民点及工矿用地、未利用土地与海拔相关关系均达显著水平;除水利设施用地外其余各类土地利用类型与坡度均显著相关;除耕地、草地和居民点及工矿用地外,其他土地利用类型与坡向的相关关系均不显著。

| Abstract: | The relationships between spatial distribution regularity of different types of land uses and terrain factors in Longxian,Shaanxi Province were studied in terms of the distribution feature of spatial pattern of land use.With the support of GIS software ArcGIS 9.3 and the use of Spss17.0 software we revealed the correlation between spatial distribution of land use and terrain factors.The results showed that except forest land and grassland,other land use types mainly concentrated at an altitude of less than 1500 meters and the area where the slope less than 15 °.Elevation and slope have a important influence to the land-use type distribution.Aspect has less effect to the distribution of land use type. |
