摘　　要：研究目的:探索农用地分等成果与第二次土地调查成果快速衔接的技术问题及其解决方法,为推进全国农用地分等成果与第二次土地调查成果衔接提供借鉴和参考。研究方法:GIS辅助与自动化等方法。研究结果:在不考虑分等因素更新的基础上,结果传递法和参数传递法传递结果和精度一致,可以较好地实现分等与二调成果的快速衔接,但是结果传递法数据整理过程要远远小于参数传递法。参数传递法可以实现分等因素更新情况下的成果衔接。研究结论:结果传递法和参数传递法为县级农用地分等成果与二调成果的快速衔接提供了有效的途径和方法。The purpose of this study is to explore how to rapidly connect the results of agricultural land gradation and the second national land survey, which will provide some experience and references for promoting this task in China. The methodology of GIS assistant and automation were used. The results indicated that without considering the change of factors’ attribute, the method of transmitting result has the same effects and precision as that of the method of transmitting factors. Both methods can connect the above outcomes well. The former method requires much less processing time than the latter. However the latter can connect the two results well regarding the update of factors’ attribute. It is concluded that above two kinds of methods provide effective ways for connecting quickly the results of agricultural land gradation and the second national land survey.
