面向区域自然保护地整合优化的风景特质评价——以青海省湟水谷地为例

全球城镇化背景下,区域生态环境逐渐破碎化.目前的自然保护地系统因行政边界限制等原因,难以确保区域生态系统的全面保护.面向区域自然保护地整合优化目标,构建包括风景特质识别和生态完整性评估2个阶段的风景特质评价方法,为实现区域生态系统的完整性保护提供基础依据.以青海省湟水谷地为例进行风景特质评价实践,获得风景特质类型、区域...

Landscape Character Assessment for the Integration and Optimization of Regional Protected Areas: A Case Study of the Huangshui Valley in Qinghai Province

Regional ecology and landscape are becoming increasingly fragmented in the context of global urbanization. The existing protected area system is difficult to ensure the comprehensive protection of the regional ecosystems due to administrative boundary restrictions. Aiming at the goal of integrating and optimizing regional protected areas, this research constructs a landscape character assessment method, which comprises the two stages of landscape character identification and ecological integrity assessment, to provide a basis for achieving the integrity protection of regional ecosystems. Taking the Huangshui Valley in Qinghai Province as an example, it carries out the landscape character assessment to obtain the background information on landscape character types, areas, and conservation priorities. The landscape character area is used as the basic spatial unit to guide the integration and optimization of protected areas in the Huangshui Valley. In particular, the integration and optimization process of the protected area system of the Daban Mountain system was highlighted.
