耕地自然质量是耕地质量评价中最重要的参数之一.为了及时地了解耕地自然质量的变化特征及成因,本文基于农用地质量动态监测,采用综合指数法和统计分析法,对县域耕地自然质量变化特征及成因进行分析.以自然质量等作为耕地自然质量变化的评价成果,研究结果表明:寻甸县耕地自然质量总体变化为先波动降低后趋向平缓,其中,水田和旱地中小麦的自然质量分值均高于水稻和玉米的自然质量分值;水田自然质量等总体变化呈先波动后趋向平缓;旱地自然质量等总体变化降低.本研究可为耕地质量等级更新和耕地质量变化监测提供参考.

The natural quality is one of the most important parameters in the evaluation of quality of cultivated land. In order to know that natural quality changes in the characteristics and causes of the cultivated land. The paper based on dynamic monitoring of the quality of the agricultural land, using the composite index method and statistical analysis, to analyze the characteristics and causes of natural change in mass of county scale. The natural quality grade as index which the change of cultivated land natural quality evaluation, results show that Xundian County cultivated natural quality overall change in trend after the first ripple of gentle, where paddy land and dry land wheat, natural quality scores were higher than rice and corn's natural quality scores. The natural quality of paddy land which overall change was the first volatility tend to gentle. But dry land overall change tend to reduce. This study could provide a reference for cultivated land quality level update and change monitoring.
