APPLICATION OF IMPORTANCE VALUE-AREA CURVE TO TROPICAL AND SUBTROPICAL FORESTS
重要值-面积曲线在热带亚热带森林中的应用

Importance value-area curve is used as a criterion for judging the minimal area of a community. It seems to be better and more significant than other ones. Importance value-area curve used as a sampling technique, is suitable for tropical rain forests and montane rain forests in Hainan, and subtropical evergreen-broadleaf forests and evergreen needle-leaf forests in Guangdong. It has been shown that importance value-area curve has higher precision and higher efficiency. This paper suggests the formulas:used for the importance value-area curve to determinine minimal area.
