河北省生态系统恢复力评价研究

Research on evaluation of ecosystem resilience in Hebei Province

随着各级国土空间生态修复工作的全面展开,生态系统恢复力评价变得越来越重要,而其关键则是选取科学合理、操作性高的评价方法。本文以河北省为研究区域,以各生态系统作为评价对象,选取气候、地形、土壤、植被等多方面影响因子,利用主成分分析法,评估森林、草原、农田、湿地等不同生态系统恢复力,最终通过叠加分析法给出全域生态系统恢复力的空间分布。研究结果显示:河北省生态系统恢复力大部分地区处于中等及以上水平,其中,燕山东部和太行山南部恢复力最高,东南部平原地区次之,西北地区恢复力最低。本研究不仅展示了河北省生态系统恢复力的空间差异性,也为生态系统恢复力在大空间尺度下的应用提供了借鉴。

With the comprehensive development of ecological restoration work in territorial space at all levels,ecosystem resilience evaluation is becoming increasingly important,reasonable and highly operable evaluation methods is a top priority.In this study,Hebei Province is selected as the research area,with various ecosystems being considered as the evaluation objects,influential factors such as topography,climate,vegetation,soil,and human activities are selected,and principal component analysis is utilized to assess the resilience of different ecosystems,such as forests,grasslands,agricultural lands,and wetlands.Finally through superposition analysis,the spatial distribution difference of ecosystem resilience in the entire region is obtained.Research findings indicate that the ecosystem resilience in most areas of Hebei Province is at the medium level and above,with the eastern Yanshan and southern Taihang Mountains having the highest resilience,followed by the southeastern plains,and the northwest region having the lowest resilience.The study demonstrates the spatial differences in ecosystem resilience in Hebei Province,and provides a reference for the application of ecosystem resilience in large spatial scale.
