The Chinese television profession from it that moment which is born in China, experienced take propagandized the attribute as the leading first stage, take creator art work attribute as leading second stage, Enters slowly has occupied the dominant position now by the cultural commodity the third stage, after at present this stage field weight standard is each column weighting the viewing ratio height, But regardless of has various understanding and the discussion to the viewing ratio, also no matter the viewing ratio essence is good or bad, the list from the data analysis starting point, it indeed can reflect and explain very many questions, In view of the fact that the author at the Central Committee Television seventh set of agriculture program " the date of the countryside " the column practical work experience with CCTV Rope Luck Switzerland Investigation Company the data feedback which column each reception of TV investigates to "the date of the countryside", Simultaneously furthermore has to the agricultural dissemination study concrete understanding, this article analyzes emphatically from the television jobholders' angle to this range pole -like viewing ratio data, obtains corresponding fords the agricultural television conversation class program the creation method and to the television medium thorough understanding.

中国电视行业从其在中国诞生的那一刻起，经历了以宣传属性为主导的第一阶段，以创作者艺术作品属性为主导的第二阶段，慢慢进入了现在以文化商品占主导地位的第三阶段，目前这个阶段业界的衡量标准就是各频道各栏目加权后收视率的高低，但是无论对收视率有何种理解和探讨，也不管收视率的本质是好还是坏，单从数据分析的出发点来说，它的确能够反映和说明很多问题，鉴于笔者在中央电视台第七套农业节目《乡约》栏目的实际工作经验和央视索福瑞调查公司对《乡约》栏目各项收视调查的数据反馈，同时更兼有对农业传播学的具体理解，本文着重从电视从业人员的角度对这个标杆式的收视率数据加以分析，得出相应的涉农电视谈话类节目的创作方法和对电视媒介走向的理解。因此本文是建立在对《乡约》栏目的收视率数据分析、受众收视倾向分析以及《乡约》栏目的电视节目创作经验总结基础上所得出的涉农类电视访谈节目的创作规律和理念。
