三生空间视角下传统村落空间基因图谱构建及特征解析——以扎尕那村为例

Construction and Characterization of Spatial Gene Mapping of Traditional Villages from the Perspective of Production-Living-Ecological Space:Taking Zhagana Village as an Example

传统村落三生空间的优化布局有赖于对其空间特征及其内在结构的认识。文章以扎尕那村为例,从三生空间的视角建立空间基因图谱,并以此为基础确定村落三生空间基因特征。研究表明:(1)基于土地利用数据构建三生空间基因描述具有区别于单一空间基因的新维度;(2)运用参数化方法进行空间基因识别提取具有可操作性;(3)借助“三生空间关系”图形及“地理信息要素分类”编码的形式实现空间基因图谱表达可更好服务于国土空间规划;(4)基于空间基因图谱识别出的扎尕那三生空间特征明显,生态空间由9种景观类型组成,裸岩与林地是景观的基质;生活空间建设用地破碎度较高,呈自由式带状布局;生产空间形成农林牧垂直经济类型。

The optimal layout of traditional villages production-living-ecological space relies on the understanding of spatial features and their inner structure.Taking Zhagana Village as an example,the article establishes a spatial gene map from the perspective of the production-living-ecological space and uses it as a basis to determine the village s production-living-ecological space spatial gene characteristics.The results are as follows.(1)The construction of spatial gene descriptor based on land use data has a new dimension different from that of single spatial gene.(2)The spatial gene identification and extraction by parameterization method is operable.(3)The spatial gene characteristics are realized with the help of“spatial relationship between the production-living-ecological space”graphic and“classification”code of“geographic information elements”.(4)Based on the spatial gene mapping,the spatial characteristics of the production-living-ecological space in Zhagana are obvious:the ecological space consists of nine landscape types,and the bare rock and woodland are the substrate of the landscape;the living space has a high degree of fragmentation of the construction land,and is in the form of a free-form belt layout;and the production space forms the vertical economic types of agriculture,forestry,and animal husbandry.
