摘要: 以河南省焦作市为例,基于PSR模型与“活力-组织-弹性-功能”理论,使用相关遥感数据、社会经济数据等,选取可视化指标构建评价指标体系,使用层次分析法与熵权法集成模型确定指标权重,对2000—2020年景观生态健康进行评价。结果表明,2000年、2010年、2020年景观生态健康综合指数分别为0.45、0.53、0.52,整体呈南北高中间低的分布状况及先上升后下降的变化特征。景观生态健康变化较为稳定,区域改善面积大于退化面积,以相邻等级转化为主,但主要存在于中低值之间的转化,并具有向邻近区域等级转化的趋势。根据研究结果,以城市扩张及人类活动对景观生态健康影响为基础,从景观格局优化、完善生态网络布局、管控土地利用开发等出发对城市景观生态规划提出合理化建议。

Abstract: Taking Jiaozuo City as an example, based on PSR model and the theory of “vitality-organization-elasticity-function”, using relevant remote sensing data/socio-economic data, etc., visual indicators were selected to construct an evaluation index system, and the index weights were determined by using the integrated model of AHP and entropy weight method, and the landscape ecological health from 2000 to 2020 was evaluated. The results showed that the comprehensive index of landscape ecological health in 2000, 2010 and 2020 was 0.45, 0.53 and 0.52, respectively, showing the overall distribution of high in the north and south, low in the middle and the changing characteristics of rising first and then falling. The change of landscape ecological health was relatively stable, the area of regional improvement was larger than that of degradation, and the transformation was mainly based on adjacent grades, but mainly existed in the transformation between middle and low values, and there was a trend of transformation to adjacent regional grades. According to the research results, based on the impact of urban expansion and human activities on landscape ecological health, it was put forward reasonable suggestions on urban landscape ecological planning from the aspects of optimizing landscape pattern, improving ecological network layout, and controlling land use and development.

Key words: landscape pattern, dynamic assessment of landscape ecological health, Yellow River Basin, Jiaozuo City
