摘要
对黄山松 (Pinustaiwanensis)三个群落采用随机样方 (randomquadrats)、相邻格子样方 (contiguousgridquadrats)、中心点四分法 (point centeredquarter)和最近相邻法 (nearstneighbor) 4种抽样方法进行分布格局研究 ,并对各方法在种群分布格局研究中的适用性予以客观评价 ,比较其在种群分布格局测定分析中的效用 .结果表明 ,随机样方和相邻样方能得到相同的结果 ,是理想的抽样方法 ,但鉴于随机样方的本身缺点 ,相邻格子方法为最佳取样技术 .
Studies were conducted on spatial pattern and sampling technique of the natural pinus taiwanensis communities by four methods,random quadrats, contiguous grid quadrats, point-centered quarter method and nearest neighbor method of four sampling method in three communities.Then the utility of four methods in analyzing the population pattern were compared, and the applicable function on spatial pattern by four methods were objectively appraised.The analyzing results indicated that the random quadrats methed and contiguous grid quadrats merhod had similar precision, but contiguous grid quadrats method had minimum errors and random quadrats methed had disadvantage in itself,therefore, contiguous grid quadrats method was the best sampling technigue.
