| 摘 要： | 以陕西省汉中市洋县为研究对象,结合GIS技术,分析了该地区土地利用的类型、面积、空间分布及其与地形因子之间的关系.结果表明:(1)该区土地利用结构不很合理,未利用土地面积过多;(2)从坡度和海拔与不同土地利用类型之间的关系可以看出,耕地、园地、建筑用地均集中在坡度小于8°、海拔小于800 m的区域,随着坡度和海拔的增大,土地利用类型逐渐以林地和牧草地为主.

| Abstract: | By taking Yangxian, Hanzho ng City, Shaanxi Province as an example, GIS technology was used to analyze the type,size,and spatial distribution of land resources in the region. Results are as follows: (1)The landuse structure was not appropriate and too much land was not used.(2) The analysis of land used,inview of slope and elevation, indicated that the cultivated land,gardens,and construction sites were concentrated in the areas with slope less than 8 and elevation less than 800m above sea level.As slope and elevation increased, woo dlands and pastures became the predominant landuse types. |
