县域景观特征管理单元划分方法——以武胜县为例

为了解决目前国内景观特征研究多以大尺度为主且以自然条件为基础, 缺少实际管理意义的问题, 尝试从县域层面进行景观特征单元的划分, 并与现有行政管理单元相结合, 提出发展建议。依据武胜县30 m高程、坡度和土地利用数据, 将武胜县域划分为100 m×100 m的栅格网络, 利用 ArcGIS和SPSS进行二阶聚类分析。结果显示, 武胜县可以划分为7类景观特征管理单元, 单元内部自然地理特征相似, 组间差异显著。将武胜县按聚类结果划分为较单一镇域、较单一村域和较复杂村域 3 种不同的管理模式, 并分析较复杂村域的成因, 提出管理策略。最后, 从景观特征保护出发, 对武胜县 7 处建成区提出规划管理建议。

Classification of County Natural Landscape Governance Units for Wusheng

Ecological regionalization research in China were focused on large scales and based on natural conditions, which is unable to provide practical suggestions for rural development. In this study, the classification of natural landscape governance unit framework was proposed in Wusheng County with cluster analysis, which may serve as the basis in planning. Three variables were considered in the analysis—30 m elevation, slope and land use, which were used in a Two Step Cluster analysis to define landscape types. According to results, Wusheng County can be divided into seven kinds of landscape governance units. The internal geographic features of the unit are similar, and the differences between the groups are significant. Three different governance modes can be defined: single town, single village and complex village. Analyzing the causes and proposing governance strategies is necessary for complex villages. The development strategy of the seven built-up areas of Wusheng are proposed.
