摘要
以吉林省汪清县金沟岭林场的落叶松人工林与云冷杉天然林为例,运用计量模型为主的林分经济效益系统分析方法,选取净收益、效益成本比等评价指标比较二者经济效益。结果表明,云冷杉天然林投入较落叶松人工林少3.24元.m-3,且每公顷的净收益、效益成本比均高于落叶松人工林。
Taking the larch plantation and the natural-fir forest in Jingou ling Forest Farm in Jilin Province as an example, using the model-based measurement, the economic benefit system analysis method was described. Indices such as the net income the ratio of the benefit to cost were applied to weight the economic benefit of two types of forests. The results showed that from the investment perspective, the natural forest was 3.24 yuan less than the larch per cubic metre. Further more, the net income of the former was higher than the later, and two times for the ratio of benefit to cost.
