侗族聚落空间形态演变的生态因素及其影响

通过对侗族聚落空间形态演变趋势的分析,研究侗族聚落空间形态演变的生态因素及生态影响。研究表明：侗族总人口的快速增长及其结构的多样性使得民居建筑在数量、形态和功能需求上产生变化;物质流和信息流的变化使得传统价值观和生活方式改变,由此导致聚落空间形态的演变。而聚落空间形态的演变对民居的生态系统影响则表现在自然生态系统的失衡危险和对民居社会生态系统中＂款＂组织形态这一核心因子的破坏。二者之间有着互为因果的密切关系。

Ecological factors and impact in space form evolution of Dong settlement

Based on the analysis to the characteristics of space form evolution in Dong settlement,this paper reviews the ecological factors and the ecological impacts of this kind of evolution.The results show that：the rapid growth of the total population of Dong and the diversity of the population make the structure of residential buildings change in number,shape and function;The change of material flow and information flow change traditional values and lifestyle,which leads to the evolution of spatial form of the settlement.And the effect of this evolution on the residential ecosystem lies in two aspects：one is the unbalance of natural ecosystems;the other is the destruction of the core factors,kuan,a tissue morphology in the residential social-ecological systems.This study shows that the space form of Dong settlement and residential ecosystem is a cause-effect relationship.
