This article is based on the research of Mr. Li Yinghai"s monograph the modes of Music of the Han nationality and their harmony, his music composition and a series of his vocal music works, piano works. From the structure of the chord, the harmonic progression, the modes and tonality, texture composition style, the style of dealing with the skill and technique of national music sound simulation, etc. the author expounds Mr. Li Yinghai"s great achievement and his precious experience on academic research and application on national mode harmony in detail.1. Music composition should regard nationalitys traditional music as foundation, and at the same time use European traditional skill and technique of music composition for reference, seek the harmony of traditional skill and technique, modern idea and national style. Only in this way could we promote research of the national music theory and creation of the national music.2. Theory stems from practice, guides practice again at the same time. And theory is developing, perfecting constantly in practice.

文章以黎英海先生的理论专著《汉族调式及其和声》以及他创作、改编的一系列声乐作品、钢琴作品为研究对象，从和弦结构、和声进行、调式调性、织体写法、间音处理手法、民族音乐音色模拟技法等方面详细论述了黎英海先生在民族调式和声理论的研究与应用上取得的丰硕成果与宝贵经验及其给我们的两点启示：1、音乐创作应以民族传统音乐为根基，以欧洲传统作曲技法为借鉴，努力探求音乐创作中传统技法、现代理念与民族风格的和谐统一，以此推动民族音乐理论的研究与民族音乐的创作。2、理论来源于实践，同时又指导实践，并在实践中不断发展、完善。
