摘要
通过对成都平原及川中丘陵地区１９９１年底耕地资源本底值调查和１９９２、１９９３和１９９４三个年度的耕地变化情况以及非农建设占地状况的监测研究，探索出了一套适合重点农区大面积耕地资源宏观调查与动态监测的遥感技术方法，解决了采用常规调查方法速度慢、耗费高、大面积调查难以完成和不便于重复监测等问题。本文着重探讨该调查方法中的几项有关技术。
A flexible prooedure for surveying and monitoring of agricultural land on a large area were searched out through several case studies during tile peneds of 1991～1992.1992～1993 and 1993￣1994,which was proved successfully in shortening purveying duration,cutdown of cost,and repeative monitoring of large areas.The thesis mainly deslt with several key techniques.
