【摘要】 分层技术是遥感分层抽样调查与监测方法中的关键技术之一。本研究以四川省为调查研究区，通过对影响农用土地利用类型分布的主要因子的综合分析，结合卫星遥感抽样技术的具体要求，确定了土地利用类型区的分层原则和依据，提出了层与亚层划分的具体特征和指标。本文以大区域地理条件和综合农业生产状况为特征指标将研究区划分为７个层，依据微地貌特征指标将层划分为２５个亚层，建立了能满足１：１０万农用土地利用现状卫星遥感宏观监测要求的二级土地利用类型区分层系统。更多还原

【Abstract】 Stratification is one of the key techniques in stratified sampling investigation and monitoring using remotely sensed data.This paper discussed the results of the research project in Sichuan Province,in which the principles and basis for the stratification of land use were defined and the features and quantitative signatures of each stratum and sub stratum were identified by means of a comprehensive analysis of the main factors affecting the distribution of land use with a combined concern on the needs of remote sensing application.A stratification system of 7 strata,representing the production conditions in agriculture,and 25 sub strata,representing the differentiation of micro landforms,was defined to satisfy the requirements of agricultural land survey in the scale of 1∶100 000更多还原
