森林是重要的自然资本,森林自然资本指数是一个从质和量两个方面评价森林资源状况的综合指标.构建森林自然资本指数需分别构建其数量指数和质量指数,其中质量指数的构建是难点.将质量指数分解为压力指数和状态指数,并用状态指数作为森林自然资本质量指数.在构建质量指数时以强可持续性原则和生态经济学原则为指导.森林自然资本质量状态指数的构建与以往国内外同类指数的构建有不同之处:一是为每个指标设定了基准;二是为天然林和人工林设定了不同的权重;三是指标合成时采用乘法合成.实证研究表明中国森林自然资本指数总体上呈上升趋势.分析的原因认为,统计核算口径的变化是造成1989—1998年间森林自然资本指数上升的主要因素;而林业生态工程的实施则是造成1999—2003年间森林自然资本指数上升的主要因素.
The forest is an important natural capital, and the forest natural capital index is a comprehensive index to evaluate the status of forest resources in terms of both quality and quantity.It is difficult to construct the index of natural quantity of forest and its quality index separately The quality index is decomposed into pressure index and state index, and state index is used as index of forest natural capital quality.The construction of quality index is guided by the principle of strong sustainability and ecological economics.Construction of the natural state quality index of forest In the past, there were differences in the construction of similar indices both at home and abroad: one was to set a benchmark for each indicator; the other was to set different weights for natural forests and plantations; and the third was to synthesize indicators using multiplication synthesis. China’s forest natural capital index generally shows an upward trend.The reason for the analysis is that the change of statistical accounting diameter is the main factor that caused the forest natural capital index to rise during the period from 1989 to 1998. The implementation of forestry eco- Natural capital index rose the main factor.
