基于土地生态敏感性评价的天水市生态产品价值分区实现研究

Ecological Product Value Zoning Realization in Tianshui City through Land Ecological Sensitivity Assessment

  • 摘要: 土地生态敏感性是反映区域土地生态问题严重程度的重要指标,而生态产品价值实现则是将生态产品的生态优势向经济优势转化的过程。在我国生态文明建设逐渐深化的背景下,研究生态产品价值的实现路径对区域生态与经济协调发展具有重要参考依据。从地形地貌、生态环境及人类活动三个维度出发选取7项核心指标作为单因子评价单元,分析了天水市土地生态敏感性程度,根据分析结果进行生态分区并提出了各生态分区内生态产品价值的实现路径。结果表明:(1)土地利用类型对天水市生态环境敏感性影响程度最大,植被覆盖度次之,坡向最小;(2)天水市土地生态敏感性整体偏高。极度敏感区主要分布在张家川回族自治县北部、武山县南部及北部少数区域、麦积区东南部。中度敏感区主要分布在天水市中部,而不敏感区呈带状分布,主要位于地势较低,起伏较小,相对平坦的河谷地带;(3)基于生态敏感性评价结果将天水市分为山地生态保育区、缓坡生态缓冲区、河谷生态开发区;(4)对三种不同的生态分区针对性地提出保护优先、协同修复及产城融合的生态产品价值实现策略,该研究为天水市生态产品价值实现模式实践提供参考。

     

    Abstract: Land ecological sensitivity serves as a critical indicator reflecting the severity of regional ecological degradation, while the valorization of ecological products represents the process of translating ecological advantages into economic benefits. Against the backdrop of China's deepening ecological civilization initiatives, exploring pathways for realizing ecological product value holds significant implications for coordinating regional ecological preservation and economic development. This study uses seven core indicators across three dimensions, topography, ecological conditions, and anthropogenic activities, to assess the ecological sensitivity of Tianshui City, followed by ecological zoning and tailored strategies for ecological product valorization. Key findings include: (1) Land use type exerts the strongest influence on ecological sensitivity, followed by vegetation coverage, while slope aspect demonstrates minimal impact. (2) Tianshui exhibits overall high ecological sensitivity, with extreme sensitivity concentrated in northern Zhangjiachuan Hui Autonomous County, southern / northern Wushan County, and southeastern Maiji District. Moderately sensitive areas dominate central Tianshui, while non-sensitive zones form linear patterns along low-elevation, flat river valleys. (3) Ecological zoning delineates three functional regions: mountainous ecological conservation zones, gentle-slope ecological buffer zones, and valley ecological development zones. (4) Context-specific strategies involving conservation-priority protocols for conservation zones, collaborative restoration frameworks for buffer zones, and integrated urban-industrial development models for valley zones are proposed to operationalize ecological product valorization. This research would provide actionable insights for implementing ecological product value realization mechanisms in ecologically fragile regions.
