以福建杉木人工林为例,采取替代法对杉木人工林环境成本进行核算。结果表明,不同营林措施对生态环境产生不同程度的影响,其中以炼山、全垦、扩穴连带、皆伐造成影响最大,环境成本分别为14801.101、15435.469、20794.86、817.949元·hm~(-2);其次,环境成本构成中,水成本支出最大,炼山、全垦、扩穴连带造成的水成本支出占各措施环境成本的79.67%、77.24%、51.78%,肥成本次之,土成本最小。
Take Fujian Cunninghamia lanceolata plantation as an example, take the alternative method to calculate the environmental cost of Cunninghamia lanceolata plantation. The results showed that different silvicultural measures had different impacts on the ecological environment. Among them, the influence of Lian Shan, Quan Ken, Lian Weichao and Jie Hu was greatest, with environmental costs of 14801.101, 15435.469, 20794.86 and 817.949 yuan · hm ~ -2). Secondly, in the composition of environmental costs, the cost of water is the largest. The cost of water produced by Lian Lian, Quan Ken, and the expansion of caverns account for 79.67%, 77.24% and 51.78% of the environmental cost of each measure, Soil costs the smallest.
