| 摘 要： | 本文采用改进的农业生态区位法,利用GIS技术,以1km×1km栅格为基本单元,计算了内蒙古自治区栅格与县域尺度的土地资源生产潜力;在此基础上,以旗县为单元,定量评价了内蒙古的土地资源承载力,结果表明:温度与水分是内蒙古粮食生产的主要限制性因子;内蒙古县域土地资源生产潜力均值为4.37 t/hm2.a,大兴安岭—阴山—贺兰山一线以东、以南地区生产潜力较高,以西、以北潜力较低。整体而言,内蒙古基于粮食安全的人口发展仍有较大空间,旗县差异显著。 |

| Abstract: | Based on the situation of food security and sustainable agricultural development,this research attempts to study systematically the issues of potential land productivity and population carrying capacity in Inner Mongolia by applying theoretical models(AEZ) at county levels, and using 1km 1km grid data and GIS technologies.The results showed that in general the temperature and precipitation are the major limiting factors of grain production in Inner Mongolia.The potential land productivity tends to be higher in southeast than in northwest areas along Da Xing An Mountains,Yin shan and Helan shan.In general,the development of population has a big space accordingto the regional food security,and varies significantly among the counties studied. |
