摘要
本文以海南坝王岭山地雨林为对象,研究了中点四分法取样与样地取样的应用。研究结果表明,根据重要值一面积曲线与重要值一点数曲线而确定的坝王岭山地雨林的最小面积为3000~4000m ̄2,最小点数为32点,32点中点四分法取样所获得的群落数据,不但极其相似于3000~4000m ̄2样地取样,而且取样效率极高,节省人力,是完全适用于热带山地雨林研究的取样技术。
The tropical montane rain forest of bawangling Gibbon natural reserve in Hainan,werestudied by using both the“quadratmethod”and the “point- centred quarter method”.Two 50m×50m quadrat and 36 point一central werer restricted at the same stand. The result showed thatthe minimal area of the tropical montane rain forest is 3000一4000m ̄2, which is determined by ofthe tropical montane rain forest is 20-32 points, which is determined by impur ance value- poliIt numbcr curve, It has been shown that the result of point一centred quarter method is higherprecsion and hisher efficicncy than the quadrat method ad judged by importance value, percentage of similarity and coefficient of community . So that . the point一centred qiarter method is suitable for the tropical montane rain forest used as a sampling technique .
