世界林业发展中的问题很多,当前议论得最多和影响最大的是大量破坏和采伐森林,造成生态环境恶化。当今世界,主要是发展中国家,为了维持生存,积累建设资金,获得赖以生存的能源,过量的砍伐森林资源出卖木材原料,大量毁林开荒,大量砍伐森林充作薪材,造成水土流失,土地生产力减低,大面积沙化。由此,大面积热带森林正在消失,这将对全球生态环境造成严重的后果。世界林业的问题,归根结蒂是森林资源问题。为了使森林资源不再继续减少;为了扩大和增加森林面积及提高森林资源的质量;为了充分、有效地利用森林资源;为了满足社会经济发展和人类生存对森林多种林产品的需求……。各国政府和林学家们采取了不少对策。

At present, the largest and most controversial issue is the extensive destruction and deforestation, resulting in the deterioration of the ecological environment. In today’s world, mainly the developing countries, in order to survive, they have accumulated funds for construction and obtained the energy they depend on for their survival. Excessive deforestation has also betrayed timber raw materials, extensive deforestation and wasteland, Land productivity reduced, large-scale desertification. As a result, large tropical forests are disappearing, which will have serious consequences for the global ecological environment. The problem of world forestry, in the final analysis, is the issue of forest resources. In order to make forest resources no longer continue to decrease; in order to expand and increase the forest area and improve the quality of forest resources; in order to fully and effectively use forest resources; in order to meet the socio-economic development and human survival of the forest variety of forest products ... .... National governments and forest scientists have taken many measures.
