摘　　要：牢牢守住粮食安全生命线、严守耕地保护红线是我国一项基本国策。随着城镇化的发展,一些地方为了提高地区经济发展水平,引入许多企业下沉乡村。在产业高速发展的同时,大量的农田因为发展需要被“非农化”,导致耕地面积减少,粮食产量受到一定影响。本文基于2020年完成的第三次全国国土调查(以下简称“三调”)成果,选取某地区作为样例,系统介绍了如何基于“三调”和第二次全国土地调查(以下简称“二调”)的数据成果,分析在过去的十年时间内,该地区耕地开发利用变化趋势,掌握耕地实际保有量情况,为该地区制定耕地保护政策提供可靠的依据,确保粮食生产安全。It is a basic national policy of our country to firmly guard the lifeline of food security and the red line of cultivated land protection.With the development of urbanization,in order to improve the level of regional economic development,some places introduce many enterprises into rural areas.With the rapid development of industry,a large number of farmland has been"non-agricultural"because of the development needs,resulting in the reduction of cultivated land area and the impact of food production.Based on the results of the third national land survey completed in 2020,this paper selects an area as an example,and systematically introduces how to analyze the change trend of cultivated land development and utilization in the past ten years based on the data results of the third national land survey and the second national land survey,grasp the actual amount of cultivated land,and provide a reliable basis for the formulation of cultivated land protection policies in the region to ensure food production safety.
