摘要
文章以科学态度及操作方法测算出全国 11类树种平均林价 ,建立了森林病虫灾害直接经济损失计算式 ,提出某区域单位重量的生物量的生态效益可认为是一个相对稳定的值的观点 ,探讨了两种估算生态效益损失的方法。
Based on the scientific attitude and operating method,the average forest-values of 11 groups of trees were calculated and the counting formulae for direct economic losses of forest pest disasters were founded.The viewpoint that the eco-benefit of unit weight biomass in some area was one relatively steady value was advanced,and two methods for estimating eco-benefit losses were discussed.
