摘要
坡度坡向是影响土地利用空间格局的因素。以韶关市大塘镇为研究区,基于DEM和土地利用现状图,利用GIS提取坡度坡向及土地利用信息,并将坡度坡向与土地利用图进行叠加分析,研究坡度坡向与土地利用空间格局的关系。研究结果表明,除林地外的土地利用类型随坡度增加而大体呈现下降趋势;除平地外,各坡向土地利用类型差异较小;坡度坡向影响光照、水分、热量等分布,进而对人类活动和土地利用空间格局产生影响。
Slope and aspect is a factor affecting the spatial pattern of land use. Shaoguan City Town as the study area, based on re- search DEM and land use maps using GIS to extract slope aspect and land use information, and slope aspect and land use map overlay analysis, slope aspect and land use study relations spatial pattern. The results showed that： ① In addition to forest land use types increases with slope and generally show a downward trend; ② In addition to the ground outside, each aspect of land use types little difference ; ③ slope and aspect influence of light, moisture, heat and other distributions, thus impact on activities and land use spatial pattern of mankind.
