摘要: 研究分析了来自中国、蒙古、缅甸、南非和德国的具有林木空间位置坐标和树种组成的试验地数据,提出了利用模型和数学手段确定森林群落最小面积的新方法。通过从样地中心设立方形样方并按10 m的间隔逐渐扩大样地边长并统计树种数的方法获取种2面积数据,并建立种2面积模型,令模型二阶导数为零或近似为零(1 ×10 -6 )来确定最小面积。研究还发现,最小面积和最大树种数的关系可用半对数模型很好描述,实践中可直接借助本研究所提出的模型用潜在的树种数来估计调查所需的最小面积。Abstract: The size of survey area is very important to p roper exp ress the characteristics of the forest communities.This paper studied on the research p lot dataset which composed by tree spatial positions data and tree speciescomposition from China, Mongolia, Myanmar, South Africa and Germany, a new app roach on determining the forestcommunities’minimum survey area p resented bymodel and mathematicsmethod. By setting quadrate samp le in thecenter of p lot and then enlarging its edge length interval 10 m to get the data of species-area curve and establish thespecies-area model, the minimum survey area can be determined bymaking the value of second derivative model iszero or app roximate zero ( 1 ×10-6 ). The study also found that the relationship of minimum area with maximumspecies can be well described by semi-logarithm and the model can be directly estimated the survey minimum areaby using potential tree species quantity in p ractice.
