| 摘 要： | 从我国耕地资源开发利用的现状入手,提出了耕地资源开发利用中存在的问题:耕地总量和人均耕地面积减少、耕地质量下降、耕地污染和生态功能退化等。然后从农作物遥感估产、土地变化监测及驱动机制研究、耕地粮食生产力和人口承载力研究等方面探讨了耕地资源及其利用领域的研究进展。最后提出了耕地资源合理开发和可持续利用的思路。

| Abstract: | Beginning with introduction of the situation of exploitation of cultivated land resource in China,several problems in this field are presented,such as decrease in total area and per capita area of cultivated land,decline in cultivated land quality,contamination and ecological function degradation of cultivated land.Then the research progresses in the field of cultivated land resource and its utilization are discussed,which include,yield estimation of crops by remote sensing,researches on driving mechanisms and monitoring of land use change,grain productivity of cultivated land,carrying capacity of cultivated land.At last the methods for reasonable exploitation and sustainable utilization of cultivated land resource are suggested. |

| Keywords: | cultivated land resource remote sensing grain productivity of cultivated land sustainable utilization |
