Study on Heptacodium miconioides Population Structure and Spatial Distribution Pattern in the Central Zhejiang Province

  • Received Date: 2005-02-03

  • On the basis of population investigation by tally in the contiguous grid quadrat,10 plots of 500 m2 in Bei Mountain,Dapan Mountain and Dongbai Mountain were investigated and analyzed to reveal population structure and spatial distributive pattern of Heptacodium miconioides in central Zhejiang Province.The result showed that there were obvious differences in the characters among the H.miconioides communities and populations.The diameter structure of different populations had only one type: spindle-like form structure: infant seedling and big tree were thimbleful,which indicated its population recession trend.With the increase of age and difference of development phases,the distribution pattern usually ranged from clump to random,and different size of blocks had been found to have an effect on the spatial patterns.The analysis showed that the spatial distribution pattern of H.miconioides populations was decided mainly by the interaction among the biological,ecological properties and environmental factors.So,conservation strategies should be focused on in-situ conservation as well as reducing human disturbance and enhancing inter-population genetic exchange.

Study on Heptacodium miconioides Population Structure and Spatial Distribution Pattern in the Central Zhejiang Province

Abstract: On the basis of population investigation by tally in the contiguous grid quadrat,10 plots of 500 m2 in Bei Mountain,Dapan Mountain and Dongbai Mountain were investigated and analyzed to reveal population structure and spatial distributive pattern of Heptacodium miconioides in central Zhejiang Province.The result showed that there were obvious differences in the characters among the H.miconioides communities and populations.The diameter structure of different populations had only one type: spindle-like form structure: infant seedling and big tree were thimbleful,which indicated its population recession trend.With the increase of age and difference of development phases,the distribution pattern usually ranged from clump to random,and different size of blocks had been found to have an effect on the spatial patterns.The analysis showed that the spatial distribution pattern of H.miconioides populations was decided mainly by the interaction among the biological,ecological properties and environmental factors.So,conservation strategies should be focused on in-situ conservation as well as reducing human disturbance and enhancing inter-population genetic exchange.
