I'm confused about the part in bold above, which lists industries: 林业 = forestry, 农业 = agriculture, 草原 = grassland, 海洋 = ocean, 资源 = natural resource, and 环境 = environment.
I don't understand what 草原……行业 ("grassland industry") and 海洋……行业 ("ocean industry") refer to, and why use these terms instead of 农业 and 渔业 ("fishing industry"), respectively, which (to me) seem more ordinary.
Question: In 林业、农业、草原、海洋、资源、环境等行业, what industries does 草原 and 海洋 refer to, and why not use 农业 and 渔业 instead?
