马克明 %J 生态学报 %D 1999 %I %X Correlation dimension of population pattern can disclose the scaling properties of spatial autocorrelation of individuals and the spatial occupation degree of population.The spatial patterns of Larix gmelini populations in Daxingan Mountains were studied.The results showed that correlation dimensions of Larix gmelini populations were high in different Larix forests(near 2),spatial autocorrelation among individuals was high,and competition among individuals was serious.The order of correlation dimensions is that: Rhododendron Larix forest(1 746)>Grass Larix forest(1 740)> Vaccinium Larix forest(1 550)> Ledum Larix forest(1 468).Correlation dimensions of Larix gmelini populations were low in Larix Betula forest(<1 512,far from 2),competition among individuals was weak,the population was in an accompaniment position.Through comparison of correlation dimension among natural Larix forests and Larix plantation,the order of spatial autocorrelation degree is Larix plantation(1 762)>natural Larix forest(1 626)> Larix Betula forest(1 434).It shows the differences of scaling property of spatial autocorrelation among individuals of Larix population in different forest types.Discussion was made on how to integrate the 3 fractal dimension methods in one study in order to describe the scale variation properties of population pattern more clearly. %K Larix gmelini %K population pattern %K correlation dimension %K spatial autocorrelation %K scale
