安徽皇甫山黄檀种群结构初步研究

通过选取9个25m×25m的样方,采用5m×5m的小样方为基本调查单位进行种群生态学的调查,研究了皇甫山黄檀种群结构,结果表明,皇甫山黄檀种群结构可分为:线性增长型种群、指数性增长型种群、线性下降型种群、指数性下降型种群等四种类型。对各样方的种群大小与大小级进行相关分析和函数拟合,各样方及整个种群的大小结构相关性不甚显著,而Q1和Q3的相关性较密切。种群结构稳中有升,该种群处于发育中期阶段。

Preliminary study on population structure of Dalbergia hupeana in Huangfushan of Anhui Province,China

The population structure of Dalbergia hupeana in Huangfushan was studied by surveying method of Population Ecology through selecting nine quadrats of 25 m×25 m and applying basic unit of the little quadrat of 5 m×5 m. The results are as follows:First,the types of population size structure of D.hupeana are classified into linear increase population,exponential increase population and linear decline population,exponential decline population;Second,the population size structure of D.hupeana in the quadrats have no significant correlation, while Q1 and Q3 have closer correlation with studying of correlation and imitating functions. The whole population structure of D.hupeana is increasing in stationary and the population is in the mid stage of the development.
