摘要
黔东南黎平县四寨村和肇兴村两个侗族传统村寨具有较高的识别性和文化价值,旅游开发强度的不同越来越影响二者景观资源格局的差异。运用景观生态学原理比较分析四寨村和肇兴村景观斑块资源的空间结构特征,采用1︰500地形图实地勾绘小班,利用ArcGIS 10.2和Fragstats 3.3软件计算景观指数。结果表明:四寨村自然斑块面积较肇兴大,人工斑块面积较肇兴少,耕地和林地是两个村落的优势斑块,四寨村大面积斑块类型多于肇兴村,林地在两个村落中均具有较大的平均斑块面积;四寨村较肇兴村斑块边缘形状更复杂而不规则;斑块边缘密度和斑块密度表明肇兴村景观异质性大于四寨村,景观破碎化程度更高;四寨村各资源类型斑块在空间配置上更为聚集。研究建议在进行侗族村落保护性开发时,注重村落内优势斑块的保护,维持景观的延续性;加强景观斑块资源的管理,合理引导斑块的资源开发,集约化发展村落,提高景观系统的稳定性。
Two traditional Dong Minority villages which named Sizhai and Zhaoxin in Liping county, southeast Guizhou are of high recognition and cultural value. Due to different degrees of tourism development, the patterns of the landscape resources of the two villages become more and more different. Based on landscape ecology principles, we compared and analyzed the characteristics of spatial structures of Sizhai and Zhaoxing villages＇ landscape patch resources by drawing the outline of patches on the 1 ： 500 topo- graphic maps and calculating landscape indices with ArcGIS 10.2 and Fragstats 3.3 software. The results show that the natural patch size of Sizhai is bigger than Zhaoxing, and the artificial patch size of Sizhai is smaller than Zhaoxing; the farmland and wood- land are dominant patches, and the large patch area in Sizhai is Bigger than Zhaoxing; the average woodland patch area is large in both villages; the patch edge shape of Sizhai is more complex and irregular than Zhaoxing; the patch edge density and patch density show that landscape heterogeneity of Zhaoxing is larger, and the landscape fragmentation degree is higher than that of Sizhai; the re- source types of patches in the space configuration of Sizhai is more gathered than Zhaoxing. Therefore, as for the Dong Minority villages＇ protective development, The study suggest that more attention should be paid to the protection of the dominant patch of woodland in order to maintain the continuity of the landscape, and we should strengthen the management of landscape resources, re- duce the degree of landscape fragmentation, guide the patch resources development reasonably, develop villages intensively, and im- prove stability of landscape system.
