省域多尺度景观特征分类体系的建立 ——以广西多民族自治区为例

景观作为人与自然相互作用结果的最终呈现,提供了一个实体可感知的媒介去理解和管理人与自然的关系。景观特征进一步提供了理解与分析景观变化程度的方法与工具,而建立景观特征的分类体系则成为管理景观变化的第一步,即建立特定区域的景观特征基准图则是判断与管理景观变化及其影响的基础与前提。基于遥感影像与空间数据,以中国广西壮族自治区为对象,尝试建立"省域-市域-地方"的多尺度景观特征分类体系,探索景观特征评估分类的技术过程与关键问题,以及其在景观分析、规划、监测管理等方面的应用与潜力。

The Establishment of Provincial Multi-scale Landscape Character Classification System in Guangxi Autonomous Region Province

As the final presentation of the result of the interaction between human and nature, landscape provides an entity perceivable medium to understand and manage the relationship between them. Landscape character further provide a mean to understand and analyze the degree of landscape change. The first step to manage landscape change is the identify and classification of landscape character. That is, the establishment of a reference landscape character map in a specific area is the basis and premise to judge and manage landscape changes and its influence. Based on remote sensing images and spatial data, this thesis tries to establish a multi-scale landscape character classification system, from province, city to local. And explores the technical process and key issues of landscape character identification and classification, and its application and potential in landscape analysis, planning, monitoring management, etc.
