我国结合次生林经营发展珍贵用材树种的战略利益

The Strategic Benefits of Developing Precious Commercial Tree Species Integrated with Secondary Forest Management in China

建立一个动态、稳定、优质的全国森林生态大系统，是培育自然财富，提升国家实力的战略举措。我国的天然林正在国家保护下走向恢复，速生丰产林在面积上已稳居世界第1，但质量有待提高。现在的一个关系更大全局的问题。是要在持续扩大造林的同时，重点提升一般森林的质量，这是培育国家自然资本的根本战略。特别是对于在面积上占主体地位的低质次生林，要采用乡土用材树种进行“补植”，即推行“近自然育林”。文中认为，提升森林资源的质量，特别是以乡土用材树种“转变”低质次生林，用30～40年的时间，就可以建立起一项总价值约为800万亿元的国家自然财富（仅立木），比现在的价值大133倍。

To establish a dynamic, stable and qualified national forest ecological macro -system is a strategic measure to cultivate natural wealth and raise nation＇s capability for China. The natural forest in China is in the process of restoration under the protection of the government. China＇s area of fast - growing and high - yielding plantation ranks the first in the world, but the quality of plantation needs to be improved. The key issue is to put the priority on the improvement of forest quality while continuously expanding plantation. The improvement of forest quality is the basic strategy for cultivating the nation＇s natural capitals. For the low - quality secondary forest which is dominant in area, it is necessary to adopt the method of replanting with indigenous species, i.e. to implement ＂ nature - approximating cultivation＂. The authors hold that by improving forest quality, especially transferring low -quality secondary forest with indigenous species, it is possible to establish for China a natural wealth （standing timber only） which is worth 800 trillions RMB yuan within 30 to 40 years, whose value will be 133 times more than that at present.
