| Abstract: | Spatial distribution pattern analysis is an important method to study the relationship between plant populations.The spatial distribution pattern of the evergreen broadleaved forest in Dapingzhang,Dongguan was analysed using Ripley′s K function.The results indicate that the dominant populations are Cratoxylum cochinchinense,Microcos paniculata and Cyclobalanopsis myrsinifolia.Cratoxylum cochinchinense is in random distribution on the scale of 1.5 to 4.5 m,and aggregate distribution on other scales.Microcos paniculata and Cyclobalanopsis myrsinifolia are in aggregate distribution.Machilus chinensis is in aggregate distribution on the scale below 11 m and random distribution on the scale above 11 m.Analysis shows that the relationship of the spatial distribution patterns between Cratoxylum cochinchinense and Microcos paniculata is in both positive and negative correlation.Cyclobalanopsis myrsinifolia is negatively correlated to Cratoxylum cochinchinense and Microcos paniculata,with strong competitive relation. |
