摘　　要：通过掌握全省耕地的数量与质量、空间分布情况,摸清云南省耕地质量空间分布特征,为合理利用耕地资源与制定耕地保护政策提供依据。本文以云南省129个县农用地分等省级数据为基础,结合该省指标区耕地分布现状,采用面积加权法计算云南省不同指标区耕地平均自然等,并采用统计分析方法分析了全省耕地自然质量等别、质量等级在空间上的分布特征。结果表明(1)云南省耕地自然质量等呈典型偏正态分布,耕地自然质量等范围为6-13等。(2)云南省耕地自然质量等平均等为10.62等,主要以中、低等地为主,总体水平中等偏低。滇南中山宽谷区耕地平均自然质量等最高,为10.39等;滇西北高山峡谷区最低,为11.42等;五个不同指标区耕地自然质量等别平均等别发展趋势与全省平均的基本一致,只有滇西北高山峡谷区等别相对较低。(3)云南省耕地以高、中等地为主,所占比例高达99.9%,其中滇中高原盆地区分布高等地、中等地比例最高。研究成果为准确的掌握土地数据、合理利用土地、制定差异化的耕地质量提升策略等提供科学依据。Through mastering the quantity and quality of cultivated land and spatial distribution of cultivated land in Yunnan Province, the spatial distribution characteristics of cultivated land quality in Yunnan Province are found out, which provides the basis for rational utilization of cultivated land resources and formulation of cultivated land pro tection policies.Based on the provincial data of farmland grading in 129 counties in Yunnan province, according to the distribution of cultivated land in the index area of the province,The average natural value of cultivated land in different index areas of Yunnan province is calculated by area weighting method.The spatial distribution characteristics of cultivated land natural quality and quality grade were analyzed by means of statistical analysis.the results indicated that： （1） The average natural quality grade of the arable land for the whole province follows the positive skewed dis tribution, The range of natural quality of cultivated land is 613. （2） the average natural quality grade, being grade 10.62, of the Arable land for the whole province is at the medium to lower level the highest average natural quality grade of 10.39occurs in the middle mountains Valley Region in South Yunnan, while the lowest of 11.42 is in the Mountainous gorge area in Northwest Yunnan,the development of the average quality of the arable land for the Five different Index area has little difference from the average natural quality grade of the whole province, Only the alpine gorge area in Northwest Yunnan is relatively low. （3） the cultivated land in Yunnan Province is mainly in the medium, or goodquality, accounting for 99.99% of the area, Among them, the Plateau Basin area in Central Yunnan has the medium, or goodquality highest proportion.The research results provide scientific basis for the accurate control of land data, rational use of land and the development of differentiated cultivated land quality promotion strategies.
