Abstract:: According to the agricultural land grading results in Yunnan Province, providing service for agricultural industrialization and accurate poverty alleviation work, we analyzed the spatial distribution characteristics of cultivated land in the study area based on county scale of cultivated land natural quality grades and the average natural quality grades by adopting the method of spatial overlay analysis and statistics. Results indicate that: (1) the overall level of the cultivated land natural quality is low, the main grades range from 5 to 9, and the average level is 8.14; (2) the cultivated land natural quality level is low, mainly middle and low level of arable land, the proportion is as high as 92.11%, the distribution of this cultivated land covers 236 villages and towns, accounting for 90.42% of the total villages and towns in the study area, including 21 national villages and towns, accounting for 8.04%; (3) there are differences in the distribution of cultivated land natural quality grades between index areas and county scale. The average natural quality grade of the cultivated land in the northeast mountain area of Yunnan Province is higher than that in the plateau basin area of Yunnan Province; there is only one county with superior levels of cultivated land, three counties with medium level of land, three counties with all levels of cultivated land except master level, and eight counties with middle and low levels of cultivated lands. Based on the above characteristics we divided the study area into four parts, and then selected typical counties, it indicated that the higher grade of cultivated land mainly distributed in these areas which are with abundant resources of field and good soil texture. This study can provide reference for the construction of a high standard of basic farmland and the accurate poverty alleviation work in Wumeng mountainous area in Yunnan Province.
