基于生态承载力下西江苗寨的聚落空间弹性预测

The Settlement Space Elastic Prediction Based on Ecological Carrying Capacity of Xijiang Miao Village

西江苗寨位于贵州省黔东南地区,具有较高的生态价值和人文价值。开展西江苗寨动态的空间预测和分析,对于黔东南地区民族村落的保护性规划具有重要意义。本文在实地调研和大量资料搜集的基础上,对西江苗寨空间生态结构和现存问题做出了分析和总结。利用弹性系数理论对其建筑空间进行了预测分析。研究结果表明:(1)空间生态结构研究结果显示该地区景观生态结构较为理想;(2)聚落空间形态研究显示该地区存在过度扩建和盲目规划等现存问题;(3)弹性系数分析显示当地未来的生态格局将处于良性发展的态势当中,但应该进一步降低建筑空间的增长。

The Xijiang Miao village is located in Southeastern Guizhou Province,it has high ecological value and humanity value. It has important significance for the protection planning of the ethnic villages in the southeast of Guizhou Province that carry out the state space prediction and analysis of Xijiang Miao village.The paper investigated the field and collected a great mass of data,and analysed the problems of the ecological structure of the Xijiang Miao village space. And the theory of elasticity was used to forecast and analyze the architectural space. The results are as follows：（ 1） The findings of the ecological space structure indicate that the landscape ecological structure in this region is more ideal;（ 2） The findings of spatial form in settlement indicate that this region has some existing problems,such as excessive expansion and blindly planning（ 3） Elastic Coefficient Analysis indicate that the ecological pattern of the future will be in a benign development trend,but it should further reduce the growth of the building space.
