摘要
基于统计学的次数分布原理,根据云南省的地形地貌特点,选用耕地总面积、土地垦殖率、水田面积、大于6°坡耕地面积、大于25°坡耕地面积以及人均耕地面积为分析指标,以SPSS软件和Map GIS为分析工具,得出云南省多耕地分布区和少耕地分布区。结果表明:云南省耕地、水田主要分布于滇东南、滇南和滇西南地区;土地垦殖率受地形和人口影响,高垦区位于滇东北和滇东,低垦区位于滇西北;坡耕地受地形影响主要集中在滇东北和滇西南地形坡度较大地区;耕地面积大的地区人均耕地多,而经济发达,人口密度大的地区人均耕地少。
According to the frequency distribution of statistical methods and the terrain and geomorphology features,the SPSS and MapGIS was used to research on multi cultivated land distribution area and less arable land distribution area in Yunnan Province with 6 indexes： total cultivated land areal,land reclamation rate,paddy field area, 〉6°slope cultivated land, 〉25°slope cultivated land,farmland areas per person. The results showed： cultivated land,paddy field mainly distributed in the southeast,south,and southwest of Yunnan; Land reclamation rate affected by topography and population,that high reclamation area is located in the northeast and east of Yunnan,low reclamation area is located in the northwest of Yunnan; The main focus of the slope cultivated land is mainly concentrated in the southwest of Yunnan and slope region of northeast of Yunnan; The area per capita of arable land is more than that of the region,while the economy is well developed,and the area per capita of the population density is little.
