摘要

[目的] 构建生态系统健康与生态系统服务关联的自然资源生态安全评估框架，分析城市化过程中自然资源生态安全的演变规律，为区域国土空间优化和生态文明建设提供理论依据。[方法] 基于生态系统健康与生态系统服务关联的视角，构建“贡献力—活力—组织力—恢复力”的自然资源生态安全评估框架，综合运用InVEST模型、景观指数和德尔菲法评估武汉市2000和2021年的自然资源生态安全，并分析其时空演变规律。[结果] ①2000和2021年武汉市自然资源生态安全指数分别为0.394 4和0.374 5，生态安全等级在空间上呈现中部低、四周高的分布格局，且黄陂区生态安全水平最高； ②2000—2021年武汉市自然资源生态安全整体呈下降趋势，下降的地区主要沿中心城区边缘呈环状分布，“低安全”范围有从中部核心区逐步向外扩张的趋势，且“中等安全”降为“较低安全”，“较高安全”降为“中等安全”的分布范围较广。[结论] 城市扩张过程中面对自然资源生态安全不断下降的压力，应进一步加强国土空间规划的引领作用，严惩非法侵占生态用地，加强生态空间的保护。

Abstract

[Objective] An assessment framework for ecological security evaluation of natural resources was constructed to further analyze its evolution law in response to urbanization

in order to provie references for regional territorial space optimization and ecological civilization construction. [Methods] Based on the correlation between ecosystem health and ecosystem services

an ecological security framework based on “contribution

vigor

organization and resilience” was constructed. By using the InVEST model

landscape indices

and the Delphi method to evaluate the ecological security of Wuhan City in 2000 and 2021

the temporal and spatial evolution of ecological security was also analyzed. [Results] ① The ecological security index of Wuhan City was 0.394 4 in 2000 and 0.374 5 in 2021. Ecological security level showed a spatial distribution pattern of “low in the middle and high in the surrounding area”. The ecological security level of the Huangpi District was the highest. ② From 2000 to 2021

the overall ecological security of Wuhan City showed a downward trend. The declining areas were mainly located in a ring along the edge of the central urban area. The distribution of the “low security” area tended to gradually expand from the central core area. The transition of areas from “medium ecological safety” to “low ecological safety” and from “high ecological security” to “medium ecological safety” was widespread. [Conclusion] Urban expansion has resulted in declining ecological security of natural resources. Therefore

territorial space planning should be further strengthened

including punishments for illegal occupation of ecological land and strengthening the protection of ecological space.
