阔叶混交林在森林生态系统中,具有很高的生态效益,它对维护自然生态平衡起着极其重要的作用。因此,保护和发展阔叶混交林,建立多层次复合结构的森林生态系统,改善和提高现有森林生态效益,已成为十分紧迫的课题。一、保护和发展阔叶混交林的作用及其深远影响1.阔叶混交林是森林生态系统中的一种高级形式,它能充分利用地面和空间,能量流动和物质循环的功能最高,构成一个良好的森林生态环境,特别是天然阔叶混交林,是个具有多层次复合立体结构的森林生态系统,这样良好的生态环境是野生动物栖息繁衍的好场所,利于形成最多的生物种类、数量和最高的生物产量,使环境和生物、生物
Broad-leaved mixed forest in the forest ecosystem, has a high ecological benefits, it plays a vital role in maintaining the natural ecological balance. Therefore, the protection and development of broad-leaved mixed forests, the establishment of multi-layered forest ecosystems and the improvement and enhancement of existing forest ecological benefits have become urgent topics. First, the role of broad-leaved mixed forest protection and development and its far-reaching impact 1. Broad-leaved mixed forest is a forest ecosystem in advanced form, it can take full advantage of the ground and space, energy flow and material circulation of the highest functions A good forest ecosystem, especially the natural broad-leaved mixed forest, is a forest ecosystem with multi-level composite three-dimensional structure. Such a good ecological environment is a good place for wild animals to breed and habitat, which is conducive to the formation of the largest number of biological species, The highest bio-yield makes the environment and biology, biology
