摘要:

以多元资源整合的视角构建生态-文化复合廊道网络 能够帮助有效地识别区域协调发展的基本格局及关键矛盾。基 于MCR模型量化阻止物种迁徙与扩张的难易程度，有效预测 和评估区域内生态风险的同时，依据电路理论提取成渝地区重 要生态廊道；以各时期历史文献和现行国家级文保单位名录为 依据，通过点位与线路筛选、主干和密度分析识别重要文化廊 道；通过廊道叠合和廊道密度分析形成生态-文化复合廊道网络 格局以及双因子廊道密度等级的空间分布，明确了成渝地区生 态与文化资源的整体线性分布特征与各地区发展潜力，为促进 成渝地区资源整合、流动与高效利用，支撑生态和文化资产的 全面协同保护以及区域的一体化可持续发展提供依据。

Abstract:

Constructing an ecological-cultural composite corridor network from the perspective of multiple resource integration can help to effectively identify the basic pattern and key contradictions of regional coordinated development. Based on the MCR model, the study quantifies the difficulty of preventing the migration and expansion of species, and evaluates the ecological risks and extracts the important ecological corridors in the area based on the circuit theory; according to the historical documents of each period and the list of national cultural heritage units, the study identifies the important cultural corridors through the identification of the points and routes, and the analysis of the main trunks and densities, and with corridor stacking and the analysis of the corridor densities, the network pattern of ecological and cultural composite corridors as well as the spatial distribution of two-factor corridor density levels are formed, which clarifies the overall characteristics of ecological and cultural resources in the area as well as the development potentials, providing the basis for promoting the integration, mobility, and efficient utilization of the resources in the area, and for supporting the comprehensive conservation of the ecological and cultural assets as well as the integrated sustainable development.
