基于可持续发展目标(SDGs)的乡村景观资源评价——以成都市新都区为例

Evaluation of rural landscape resources based on Sustainable Development Goals (SDGs): a case study in Xindu District, Chengdu City

  • 摘要: 乡村景观的可持续发展已成为实现可持续发展目标(SDGs)的重要环节,因此中国乡村景观资源的可持续发展亟需建立科学的、本土化的评价体系。研究以成都市新都区乡村为研究对象,基于景观的人类活动参与程度从自然景观资源、半自然景观资源和人工景观资源三个维度构建评价体系,基于SDGs选取27个具体指标并建立框架,结合熵值法进行权重赋值,对新都区127个行政村进行量化评价。结果表明:(1)新都区乡村景观资源可持续发展水平存在显著空间差异,乡村景观资源的可持续发展水平与城市化区域和主要河流流域呈现显著相关性;(2)新都区乡村景观资源可持续发展状况不平衡,高分村庄占比较少;(3)景观资源可持续性主要依赖于自然与半自然景观资源。研究通过将SDGs与景观类别结合,实现了SDGs在乡村这一小尺度区域的本土化应用,为解决SDGs长期以来的尺度不匹配问题提供了解决思路,为新都区乡村景观资源精细化评价、乡村规划及自然资源管理实践提供了科学依据。

     

    Abstract: The sustainable development of rural landscape has become an important link to achieve sustainable development goals (SDGs), so it is urgent to establish a scientific and localized evaluation system for the sustainable development of rural landscape resources in China. The rural areas in Xindu District of Chengdu City were selected as the research subject, based on the degree of human activity involvement in the landscape, an evaluation system was constructed from three dimensions: natural landscape resources, semi-natural landscape resources, and artificial landscape resources. Guided by the Sustainable Development Goals (SDGs), 27 specific indicators were selected, and an evaluation framework was established. The entropy method was employed to assign weights, enabling a quantitative assessment of 127 administrative villages in Xindu District. The findings revealed that: (1) There are significant spatial disparities in the sustainable development levels of rural landscape resources in Xindu District, and the sustainabled development level of rural landscape resources was significantly correlated with urbanizaiton areas and major river basins; (2) The sustainable development status of rural landscape resources in Xindu District was uneven, with a relatively small proportion of villages achieving high scores; (3) The sustainability of landscape resources mainly relied on natural and semi-natural landscape resources. By combining the SDGs with landscape categories, this study achieved the localization application of SDGs in this small-scale rural area, which provided a solution to the long-standing issue of scale mismatch of SDGs implementation, and provided a scientific foundation for the fine evaluation of rural landscape resources, rural planning and natural resource management practices in Xindu District.
