国家公园
“国家公园”的概念源自美国，名词译自英文的“NationalPark”，据说最早由美国艺术家乔治·卡特林（GeogeCatlin）首先提出。1832年，他在旅行的路上，对美国西部大开发对印第安文明、野生动植物和荒野的影响深表忧虑。他写到“它们可以被保护起来，只要政府通过一些保护政策设立一个大公园…一个国家公园，其中有人也有野兽，所有的一切都处于原生状态，体现着自然之美”。之后，即被全世界许多国家所使用，尽管各自的确切含义不尽相同，但基本意思都是指自然保护区的一种形式。
设立国家公园，其主要的意义和作用大致可概括为三大方向：
一是景观资源的保存与保护。
二是资源环境的考察与研究。
三是旅游观光业的可持续发展。
经过一百多年的研究和发展，“国家公园”已经成为一项具有世界性和全人类性的自然文化保护运动，并形成了一系列逐步推进的保护思想和保护模式。
国家森林公园就是国家级的森林公园。
