摘要

为了研究坡度因素对土地利用/覆被分布及其动态变化的影响

以陕西省西安市长安区为研究区

采用数字高程模型、遥感影像及相关辅助数据

应用GIS手段提供的空间分析方法

将长安区地形进行坡度分级

把两个不同时期的遥感影像解译结果与坡度分级图进行了空间叠加分析。研究结果表明

耕地、建筑用地、水域等分布在坡度较小范围

林地、草地的坡度分布范围近似于正态分布。不同年份各土地利用类型在相同坡度所占面积比例基本不变;不同坡度范围内的土地利用变化不尽相同。其它土地类型向耕地和建筑用地的转化主要集中在低坡度范围内

而其它土地类型向林地和草地的转化在整个坡度范围上大体呈正态分布。因此

坡度因素是土地利用/土地覆被的重要影响因素

坡度因素对土地利用格局具有明显的控制作用。

Abstract

In order to study the effects of slope on land use/land cover distribution and its dynamic change

taking Chang′an District of Xi′an City

Shaanxi Province as a case study area

classified the slope derived from the digital elevation model

and then a spatial overlay analysis has been done for slope map and land use map derived from remote sensing maps.The results showed that cultivated field

construction land

water mainly distributed in areas with slight slope

and woodland

grassland distribution on slope showed a normal distribution.The percentage of different land use types in same slope area was essentially same in different years while different land-use change existed in different slopes.The conversion of other land use types to construction land and the farmland mainly occurred in the slight slope area while the conversion to forest and grassland showed a normal distribution in the whole range of slope.The slope is an important factor to land use/land cover distribution and land use pattern.
