第三次全国国土调查农用地分析与耕地保护对策

第3次全国国土调查以来,虽农用地面积有增加,但耕地数量比第2次全国国土调查期间有所减少,国家提出要落实“长牙齿”的耕地保护硬措施,严守1.2亿hm2（18亿亩）耕地红线,防止耕地非农化、非粮化。选择2个县级数据库,从调查的角度分析三调数据库种植属性和恢复属性,得出因区位原因出现平原区与山区耕地种植情况差异大、耕地流转方向不同的结论,最后提出了耕地保护的3点对策。 

Analysis of agricultural land and Countermeasures for cultivated land protection in the third national land survey

Since the third national land survey, although the area of agricultural land has increased, the number of cultivated land has decreased compared with the second adjustment period. The state proposes to implement the hard measures of "long teeth" for cultivated land protection, strictly abide by the red line of 1.8 billion mu of cultivated land, and prevent the non-agricultural and non grain transformation of cultivated land. This paper selects two county-level databases to analyze the planting attributes and restoration attributes of the three transfer database from the perspective of investigation, and comes to the conclusion that due to regional reasons, there are great differences in cultivated land planting between plain areas and mountainous areas, and there are different directions of cultivated land transfer; Finally, three countermeasures for cultivated land protection are put forward.
