森林资源与森林生态效益的相关性。森林资源是森林生态效益的整体;森林涵养水源、保持水土等效益是“全程性”的,而森林改善小气候,消除噪声、游憩等效益是局部性的;森林的木材效益与森林资源的相关是“单一性”的,而森林生态效益是“多因子性”。就整体而言,主要是改善生态环境,获取林产品是第二位的。生态林业要求森林植被多样性,往往是一林多用,追求长期稳定。就林业生态工程综合效益评价方法进行分析。
Correlation between forest resources and forest ecological benefits. Forest resources are the overall ecological benefits of forests. Forest conservation of water sources and soil and water conservation benefits are all-encompassing, while the benefits of forests in improving microclimates, noise and recreation are local. The benefits of wood and forest resources The correlation is “singleness ”, while the forest ecological benefit is “multi factor ”. As a whole, the main objective is to improve the ecological environment and obtain forest products second. Ecological forestry requires diversity of forest vegetation, often a multi-purpose forest, the pursuit of long-term stability. The comprehensive benefit evaluation method of forestry ecological project is analyzed.
