四川资阳话声调系统的特点与成都话、重庆话基本一致，总的来看，资阳话单字调有4个：阴平(45)、阳平(21)、上声(42)、去声(213)。在今资阳话中，古浊声母字、古入声字消失，平分阴阳，阳平字数量大大增加。四川资阳话的两字组连读可以分为重叠式与非重叠式两大类，重叠式的变调规律以二字组中的后字变为中升调为主。非重叠式的字组变调规律比较复杂，本文从带词缀的变调、复合式构词变调以及儿化音变调三个方面对其音变特征进行分析。资阳话中复合式构词变调受一定的共时语音条件制约，但不仅仅受其控制，同时也与字组内部语法结构有较密切的关系。
The characteristics of the tone system of Ziyang dialect in Sichuan are basically consistent with those of Chengdu dialect and Chongqing dialect. In general, there are 4 tones in Ziyang dialect: Yin ping (45), Yang ping (21), Shangsheng (42) and Qu sheng (213). In today's Ziyang dialect, the ancient turbid initials and the ancient entering tone characters have disappeared, flat sound divided into Yin ping and Yang ping, and the number of Yang ping characters has increased greatly. Disyllabic tone sandhi of Ziyang dialect of Sichuan province can be divided into two categories: overlap type and non-overlap type, and the regulation of overlapping tone sandhi is dominated by the change of the back word into the middle rising tone. The law of non-overlapping disyllabic tone sandhi is rather complicated. The paper analyzes the characteristics of tone sandhi in three aspects: the tone sandhi with affixes, the tone sandhi in compound word formation and the tone sandhi in erhua. In Ziyang dialect, compound word-formation tone sandhi is restricted by certain synchronic phonetic conditions, but not only controlled by it, but also closely related to the internal grammatical structure of word group.
