森林作为陆地生态系统的主体,是人类发展不可缺乏的重要资源,是人类赖以生存的基础。森林的被破坏,不仅威协着野生动物的生息繁衍,破坏了生态链的平衡协调运转,而且最终威胁着人类的生存。无数事实已反复证明,森林在改善生态环境,维护生态平衡中起着关键性的作用,森林资源一旦被破坏,就不可避免地造成野生动物种类锐减,使许多野生动物成为濒危动物,野生动物种类的减少,又会使生态失去平衡,人类亦会受到大自然的严厉惩罚。近几年我国西北地区濒繁出现的沙尘暴,有一年比一年多的趋势,这是大自然对人类乱砍伐森林,破坏植被的行为报复。据有关部门统计,我国现有沙化土地168万平方公里,就整体
As the main body of the terrestrial ecosystem, the forest is an indispensable and important resource for human development and the basis for human beings to survive. The destruction of the forest not only helped the wild animals to breed and breed the balance of ecological chain, but also ultimately threatened the survival of human beings. Countless facts have repeatedly proved that forests play a key role in improving the ecological environment and maintaining the ecological balance. Once the forest resources are destroyed, the species of wild animals will inevitably decrease, causing many wild animals to become endangered animals and wild animals The reduction of species will again bring about an imbalance of ecology and mankind will also be severely punished by nature. In recent years, the dust storm in the northwestern region of our country has been on the rise for many years. This is a nature retaliation for deforestation and destruction of vegetation by nature. According to the relevant department statistics, China’s existing desertified land 1.68 million square kilometers, on the whole
