通过对土地利用类型区的分层技术、卫星遥感抽样技术、样方调查方法、数据库建立、数据汇总与外推方法、数理统计分析与精度评估等６个专题的重点研究，探索出一套四川省农用土地利用现状卫星遥感抽样调查与监测的技术方法。该技术方法实用性和可操作性较强，已在四川省实施应用，完成了１∶１０万农用土地利用现状抽样调查。土地利用类型区分为７个层２５个亚层，抽样数为１１８个，样方大小为１０ｋｍ×１０ｋｍ（即１００ｋm₂），实际抽样率为２．０％。应用结果表明：在合理分层的基础上，采用卫星遥感抽样与地理信息系统相结合的方法，能满足土地利用现状宏观调查与监测的精度要求。

On the basis of the stratification of the regions of land use type,by using the satellite remote sensing data and sampling technique,the technic method of the macro monitoring of the agricultural land resources in Sichuan Province has been established and the survey of the present situation of the utilization of the agricultural land on the scale of 1∶100 000 has been completed. This study also has made the special theme researches on the method of the sample square survey,the establishment of data base,the gathering together and extrapolation of data,and the statistical analysis and accuracy assessment method of data. The regions of the land use type of the studied area are divided into 7 strata and 25 substrata. The number of the sample square sampled is 118. The size of the sample square is 10×10km₂. The actual sampling rate is 2.0%. The application results show that on the basis of rational stratification,adopting the method of combining the satellite remote sensing sampling and GIS can meet the accuracy requirements of the macro survey and macro monitoring of the present situation of land use. This paper emphatically introduces the technic methods which have relation to this study.
