进入新世纪以来,随着国家对生态环境的日益重视以及森林资源也是战略资源的思想认识的转变,作为量化考核指标之一的森林覆盖率也日渐成了国与国、地区与地区进行横向对比的参考系。在此背景下,全国各地国有林场、集体林场纷纷开荒造林、封山育林、退耕还林,短短几年全国森林覆盖率在经过九十年代锐减之后又呈现出回升的态势,有些地方甚至超过50%,成了名副其实的“林木大省”、“森林城市”。由于我国山地众多耕地有限而山区人口分布广的国情,导致我国在“大跃进”式植树育林的同时,纷纷将侧重点放在种植速生林等经济林上,其实这也是解决山区贫困人口收入来源问题的一个符合实际的对策,但由于种种原因导致林木种植过程中出现了一系列问题,如种植结构单一造成林种结构失衡、人造林数量与质量的失衡、人造林与市场的失衡等,这些问题都需要纳入到经济适用的范畴来全局考虑。本文从分析当前林区营林生产中存在的问题入手,着重探讨了如何采用营林技术来解决营林过程中存在的问题,希望为林业经济的发展提供一些思路。
Since the beginning of the new century, with the increasing emphasis of the state on ecological environment and the transformation of forest resources from the strategic resources, the forest coverage as one of the indicators of quantitative assessment has gradually become horizontal across the country, the region and the region Reference frame of comparison. Against this background, state-owned forest farms and collective forest farms all over the country have started reforestation, closed hillsides and reforesting forests. In just a few years, the national forest coverage rate showed a rebound trend after the sharp drop in the 1990s. In some places, it even exceeded 50 %, Has become a veritable “forest big province ”, “forest city ”. Due to the limited farmland in our country and the wide distribution of population in the mountainous areas, our country led the focus of the rapid economic forest planted with fast-growing forests at the same time as the “Great Leap Forward” afforestation. In fact, this is also the solution to the incomes of the poor in the mountainous areas However, due to various reasons, a series of problems appeared during the planting of forest trees, such as the imbalance of forest structure caused by planting structure, the imbalance of quantity and quality of planted forests, unbalance of plantation and market, These issues need to be integrated into the economic area for global consideration. This article starts with the analysis of the existing problems in the forest management of forest production, and focuses on how to use the forest management techniques to solve the problems in the forest management and hopes to provide some ideas for the development of forestry economy.
