随着我国经济的快速发展,对于木材的消耗量越来越大,同时酸雨、氮沉降等生态环境环境问题越来越严重,因此大力发展林业经济,积极打造速生林业基地,走可持续发展道路,保护生态环境当前状态下树木造林的主要目的,也是发展林业生产最重要的一步。但是不适当的造林树种的选择不仅会给带来严重经济负担,还不能实现良好的生态经济效益。为此以下对于目前造林更新树种的选择进行了分析,并提出避免产生这些问题的一些措施,为现阶段的造林育种工作提供一定理论参考。
With the rapid economic development in our country, the consumption of wood is getting larger and larger. At the same time, the ecological environment and environmental problems such as acid rain and nitrogen deposition become more and more serious. Therefore, developing forestry economy vigorously, actively building fast-growing forestry bases and taking sustainable development path , The main purpose of afforestation under the current state of protecting the ecological environment is also the most important step in developing forestry production. However, the inappropriate selection of afforestation species will not only bring about serious economic burden, but also can not achieve good ecological and economic benefits. To this end, the current selection of reforestation tree species are analyzed, and some measures to avoid these problems are put forward, providing some theoretical reference for the afforestation and breeding work at this stage.
