以燕山山地华北落叶松低质低效林综合改造技术模式为研究对象,利用经济财务分析方法对于不同经营措施投入产出进行分析评价。研究表明：不同经营措施下,经过改造的华北落叶松低效林与未经改造的低效林相比,其投资利润率、净现值均有所上升,而且从总体来看人工促进更新效果最好,净现值为15590.51元/hm^2,其次依次为引进灌木为9952.99元/hm^2,带状皆伐改造为5985.39元/hm^2,群团状择伐改造为5290.05元/hm^2,封禁促进植被恢复为1192.45元/hm^2,未封禁的落叶松林仅为941.99元/hm^2。通过不同措施比较,表明这几种措施不仅适宜于燕山山地低质低效林改造,同时在经济上也是可行的。

In this paper, the writer studied the technology of inefficient forest improvement of North China larch forests on the Yanshan Mount,and used Economic and financial analysis methods to estimate the input and output under different management measures. Studies show that： Under different management measures, the profit rate of investment and Net Present Value of the tranformed North China larch inefficiency forest compared to the North China larch inefficiency forest.And overall, artificial modification is the best,which the NPV is 15590.51 yuan/hm2. Successively, introduction of shrubs＇s NPV is 9952.99 yuan/hm2, The Clearcutting transformation has the NPV of 5985.39 yuan/hm2. Alliances selective cutting transformation 5290.05 yuan/hm2. Banned promote vegetation recovery is 1192.45 yuan/hm2,and Not banned is 941.99 yuan/hm2,The results show that these measures are not only suitble to the transformation of North China larch forests on the Yanshan Mount ,but also feasible in economy.
