摘要/Abstract

摘要： 河北省张北县作为典型农牧交错区，是中国北方重要的生态防线，为了探明区内生态环境脆弱性现状及影响因素，为生态环境保护提供依据，本文采用敏感度-恢复力-压力度（SRP）模型，从生态敏感度、生态恢复力和生态压力度3个方面，综合考虑地形、气象、地下水、植被、生物多样性及人类活动等6个影响因子，选取16个评价指标，运用层次分析法-熵权法、空间自相关分析和地理探测器等方法，分析了张北县生态环境脆弱性空间格局及空间自相关性，并探讨了其主要驱动力。结果表明：1）张北县生态环境脆弱性以潜在脆弱、微度脆弱和轻度脆弱为主，三者共计占总面积的77.79%，中度和重度脆弱区分别占总面积的16.76%和5.45%。2）空间分布上，由西部往东部逐渐从重度、中度脆弱区向轻度、微度脆弱区过渡，且城镇地区脆弱性明显高于郊外地区，具有明显的空间差异性。3）张北县生态环境脆弱区分布存在显著的集聚现象，“高-高”集聚区表现为高脆弱性区域呈空间聚集状态，主要分布在重度、中度脆弱区，“低-低”集聚区表现为低脆弱性区域呈空间聚集状态，主要分布在潜在脆弱区和微度脆弱区。4）张北县生态环境脆弱性是多个指标相互作用共同驱动的结果，其中植被因子、地下水环境因子和气候因子是影响其分布格局的主要因素。

Abstract: Zhangbei County, as a typical agricultural and pastoral area, is an important ecological defense line in Northern China. In order to investigate the status and influencing factors of eco-environmental vulnerability in the area and provide a reference for ecological environment protection, this paper adopts the sensitivity-resilience-pressure (SRP) model, considers six influencing factors (terrain, meteorology, groundwater, vegetation, biodiversity and human activities) from three aspects of ecological sensitivity, ecological resilience and ecological pressure, and selects 16 evaluation indicators. Methods such as analytic hierarchy process-entropy weight method, spatial autocorrelation analysis and geographic detector were used to analyze the spatial pattern and spatial autocorrelation of eco-environmental vulnerability in Zhangbei County, and the main driving forces were discussed. The results are as follows: 1) The ecological environmental vulnerability of Zhangbei County was mainly characterized by potential, slight and mild vulnerability, accounting for 77.79% of the total area, while the moderately and severely vulnerable areas accounted for 16.76% and 5.45%, respectively. 2) In terms of spatial distribution, from west to east, there was a gradual transition from severely and moderately vulnerable areas to mildly and slightly vulnerable areas, and the vulnerability of built-up areas was significantly higher than that of rural areas, with obvious spatial differences. 3) The distribution of eco-environmental fragile areas in Zhangbei County exhibited significant spatial agglomeration. The “high-high” agglomeration areas are mainly distributed in the severely and moderately vulnerable areas; The “low-low” agglomeration areas are mainly distributed in the potentially and slightly vulnerable areas. 4) The eco-environmental vulnerability of Zhangbei County is driven by the interaction of multiple indicators, among which vegetation factors, groundwater factors and climate factors are the main factors affecting its distribution pattern.
