我国的森林资源较少,分布不均,主要集中在几片辽阔的天然林区和分散的山区。而完整的天然林是一个综合自然实验室:它是研究动植物群落发生、发育和演替现象;研究种内种间的关系以及土壤、水文、气候等方面的规律;特别是研究森林的生长、更新和经营管理的场所;同时,也是各种珍贵野生动植物的保存库和繁育场。因此,国家为了保护自然资源,开展科学研究,划定天然森林保护区是完全必要的。我国在一九五六年以来,先后在各省、区建立了一些森林自然保护区。丰林,就是其中之一。
China’s forest resources less distributed unevenly, mainly in a few pieces of vast natural forest and scattered mountainous areas. The complete natural forest is an integrated natural laboratory: it is to study the occurrence, development and succession of plant and animal communities; to study the relationships among species and the rules of soil, hydrology and climate; and especially to study the growth of forests , Update and management of the place; the same time, is also a treasure house of all kinds of precious wildlife and breeding grounds. Therefore, the state in order to protect natural resources, carry out scientific research, delineation of natural forest reserves is absolutely necessary. Since 1956, our country has successively set up some nature reserves in various provinces and regions. Fenglin, is one of them.
