向生态与经济紧密结合的精细林业发展是21世纪的主流方向。精细林业建设需要巨大载体,需要建立生态与经济密切结合的生态产业群,而循环经济是发展生态产业的核心。以雨养生态经济林逐步替代草本粮食生产,是化解粮食生产与水资源的矛盾,也是化解农田风沙患与生态环境恶化矛盾的“活力阀”。集体生态林的资源是可以计算价值的,要从政策层面设计解决生态效益价值的合理分配问题。 The development of fine forestry closely integrated with ecology and economy is the mainstream of the 21st century. The construction of fine forestry requires a huge carrier, which requires the establishment of a group of eco-industries in which ecology and economy are closely integrated, while circular economy is the core of developing eco-industries. Taking rainforest eco-economic forest to gradually replace herbaceous grain production is a contradiction between the solution of food production and water resources and a “vitality valve” to resolve the contradiction between wind-blown sand and deteriorating ecological environment. The resources of collective ecological forest can calculate the value, and it is necessary to design and solve the reasonable distribution of the ecological benefit value from the policy level.
