长期以来,由于受重采轻造思想的影响,营林跟不上采伐,导致森林资源数量、质量急剧下降,进而引起经济效益下降,特别是开发较早的林区更为严重。为了维持林区社会再生产,不得不加大采伐量,这又加剧了资源的消耗和质量下降,从而经济效益进一步下降。这种恶性循环就是造成现今林区“两危”(资源危机和经济危困)的主要根源。要使林区走出“两危”的困境,除了国家给予政策上的优惠及林区本身积极发展林木产品深加工、减少资源消耗、提高经济效益和 For a long time, due to the influence of rebuilding and rebuilding, silviculture can not keep up the harvesting, resulting in a drastic decline in the quantity and quality of forest resources, which in turn leads to a drop in economic benefits. In particular, the development of forests is even more serious. In order to maintain social reproduction in forest areas, the amount of logging has to be increased, which in turn has exacerbated the consumption and quality degradation of resources and further reduced the economic benefits. This vicious circle is the main cause of the “two crises” (resource crisis and economic crisis) in today’s forest. To make the forest out of the “two jewels” predicament, in addition to the policy concessions given by the state and the forest itself to actively develop deep processing of forest products, reduce resource consumption, improve economic efficiency and
