摘要: 用种-面积曲线和林分空间结构参数(混交度、大小比数、角尺度)-面积图解分析法,通过逐步扩大样地面积的调查,对铜陵叶山常绿落叶阔叶林群落空间与非空间结构最小取样面积进行了研究。结果表明,用种-面积曲线所得的研究区群落非空间结构最小取样面积为3 720 m2,用林分空间参数-面积图解分析方法所确定的最小面积为3 600 m2。群落空间结构与非空间结构研究的最小面积具有一致性,即用同一面积大小的样地数据进行群落空间结构和非空间结构研究是可行的。由此方法确定的铜陵叶山常绿落叶阔叶林群落非空间结构与空间结构研究的取样面积为3 600~3 700 m2

Abstract: By using the species area curves and the stand spatial structure parameters(mingling, neighborhood comparison, and uniform angle index)area diagram analysis method along with increasing the area and calculating the species diversity index and the stand spatial structure parameters, the minimum sampling area of the spatial and none-spatial structure of the evergreen deciduous broadleaf forest was studied.The results showed that the minimum sampling area of the none-spatial structure was 3 720 m2 by using species area curves, while the minimum sampling area of the spatial structure was 3 600 m2 by using the stand spatial structure parameters area analysis. Uniformity was found between the minimum sampling area of the spatial and none-spatial structure of the community. Thus it’s feasible that using the data of the same size of the plot to analyse the spatial and none-spatial structure of the community. The results indicated that the minimum sampling area of the spatial and none-spatial structure of the community is 3 600-3 700 m2.
