森林在发展国民经济和保护环境方面具有重要作用。我国森林很少,分布也不均匀,是世界上的少林国家之一。历史上我国的森林要比现在多得多,只是由于长期遭受破坏,资源才越来越少。森林的减少和毁灭,破坏了自然界的生态平衡,造成了严重的不良后果。解放后,通过植树造林,森林得到一定程度的恢复,自然面貌有所改变,农业生产有所发展,人民生活有所提高。总结古代森林资源变化的经验教训,将有助于我们加深对森林效益的认识,激发绿化祖国的热情。
Forests play an important role in developing the national economy and protecting the environment. China’s forest is very small, uneven distribution, is one of the world’s Shaolin countries. In history, the forest in our country has been much more developed than it is now, except that resources have been getting scarcer as a result of prolonged destruction. The reduction and destruction of forests have destroyed the ecological balance in nature and have had grave adverse consequences. After the liberation, forests were rehabilitated to a certain extent through tree planting and afforestation. Their natural appearances were changed. Agricultural production developed and people’s living standards improved. Summing up the lessons learned from the changes in ancient forest resources will help us to deepen our understanding of forest benefits and stimulate the enthusiasm of greening our motherland.
