一中国是一个多山的国家,山区占国土总面积的70%左右,山区人口占全国总人口的39%,这些指标都远远高出世界平均水平。一方面,中国山区自然条件复杂,土地类型多样,自然资源较为丰富。山区拥有全国40%的耕地,70%的宜牧草地(坡),90%的林地。山区生产全国三分之一的粮食,90%以上的木材以及品种众多的土特产品,而野生生物资源及水能资源等大多分布或蕴藏在山区,更是众所周知。因此,山区在国民经济中占有重要地位。另一方面,山区与平原之间又有着紧密的关
China is a mountainous country, with mountainous areas accounting for about 70% of the total land area and mountainous areas accounting for 39% of the total population, all of which are far above the world average.
