摘要:
依据云南省农用地分等成果，服务农业产业化及精准扶贫工作，通过采用空间叠加分析与统计的方法，基于县域尺度的耕地自然质量等和平均自然质量等分析了该片区的空间分布特征。结果表明：（1） 耕地自然质量总体等别偏低，以5~9等为主，平均等8.14等；（2） 耕地自然质量等级偏低，以中、低等地为主，所占比例高达92.11%，涉及236个乡镇，占该片区乡镇总数的90.42%，包括21个民族乡镇，占8.04%；（3） 耕地自然质量等在指标区、县域尺度下的空间分布存在差异。滇东北山原区的平均自然质量等高于滇中高原盆地区；仅1个县分布优等地，3个县全为中等地，3个县除优等地外均有分布，8个县分布低等地和中等地，依据上述特征划分4个区并选取典型县，表明等别较好的耕地主要集中于光热资源充裕及土壤质地良好的地区。该研究为云南乌蒙山片区高标准基本农田建设和精准扶贫工作等提供参考。
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.
