北京地区林木损失额的价值计量研究——不同森林类型的功能定位研究

A Study on the Quantitative Estimation of Forest Tree Loss in Beijing——The function localization research of different forest types

在对北京市森林类型进行细分的基础上,采用问卷调查的形式对北京地区常见的10种森林类型的各项功能进行了定位研究。通过对不同森林类型所具有某项功能认可度的统计、计算与分析,依据"认可度R≤60%为其它功能,60%<R<70%为重要功能,R≥70%为主导功能"的原则,提出了10种不同森林类型的功能定位。

Based on the forest types subsection in Beijing, the functions localization of 10 common forests types in Beijing were studied by questionnaire in this paper. Through the statistical calculating and analyzing the extent of recognition degree that functions possessed by different forest types, the functions of the 10 different forest types were put forward. And the functions were located according as the principle of the recognition degree that R ≤ 60% is other function, 60% 〈 R 〈 70% is important function, R ≥ 70% is dominant function.
