摘    要:内蒙古自治区地域辽阔,水热等基本条件相差悬殊,土地资源分异非常显著,耕地资源也表现出较明显的地域差异。本文利用内蒙古自治区50多年的统计数据和近9年的土地利用变更调查数据,分析了内蒙古自治区耕地面积、人均耕地面积变化过程,耕地面积变化过程的地域差异及耕地面积变化与粮食产量的关系。结果表明,内蒙古人均粮食产量的变化趋势随人均耕地的增减有较大起伏,两者的变化基本同步,并随社会经济的发展和人口的不断增加,人均耕地面积有减少的趋势,故从粮食生产安全角度考虑,保护耕地成为粮食生产安全的根本保障。基于此,从珍惜和保护好现有耕地,大力改善农业基础设施建设、特别是水利工程建设,严格控制非农业建设侵占耕地,切实保护耕地资源,加强基本农田的行政管理和社会监督及建立耕地利用考核体系,缩减土地征用利益空间等方面提出了耕地保护与保障粮食生产安全的对策。

关 键 词:内蒙古  耕地资源  粮食生产安全  对策

Abstract:Inner Mongolia Autonomous Region is a vast territory with disparate water resources, heat energy and other basic conditions. Geographical land resource as well as arable land resources difference are extremely remarkable. Using 50 years of statistical data and 9 years of land use change data on Inner Mongolia Autonomous Region, we analyzed cultivated area, average cultivated area change, per-capita cultivated area and regional differences in cultivated area. The relationship between cultivated area change and grain yield was analyzed on the same basis. The results indicate a high fluctuation in per-capita average grain yield in Inner Mongolian. Along with socio-economic development and population growth, per-capita average cultivated area tends to drop. With regard to grain production safety therefore, protecting cultivable land is a fundamental requirement for grain production safety. Hence this paper advances some strategies to protect farmland and ensure grain production safety. Most important of these strategies include: cherishing and protecting existing farmland; improving construction of agricultural infrastructure, especially water conservancy; controlling non-agricultural construction on farmlands; strengthening administrative and social surveillance of farmlands; and establishing inspection mechanism for farmland utilization to prevent land misappropriation.
Keywords:Inner Mongolia  Farming land resource  Grain production safety  Strategy
