摘要
引入极端气候因子(表征气候变化)、景观格局指数(指示人类活动对景观的干扰)以及人类活动强度因子(GDP和人口密度)构建了南岭生态功能区脆弱性评价体系,定量分析了气候变化和人类活动对生态脆弱性的影响。结果表明:(1)近13年南岭生态功能区总体上属于轻中度脆弱,并呈现自西向东递减的趋势;(2) 2000—2013年,生态脆弱性呈现减小的趋势,主要表现为微度和轻度脆弱区面积减小,而中、重度脆弱区面积增加;(3)土地利用、气候变化和人类活动是影响生态脆弱性时空变化分布格局的重要因素。研究结果可以为南岭生态功能区的脆弱性生态环境的保护和精准修复提供决策和数据支持。
The extreme climatic factors (indicating the climate change), landscape pattern index (indicating the disturbances of human activities on the landscape) and human activity intensity factor (GDP and population density) were introduced to construct the vulnerability assessment system, and then quantitatively analyze the impacts of climate change and human activities on the ecological vulnerability. The results showed that:(1) During the past thirteen years, the ecological vulnerability generally belonged to mild and moderate levels and showed a decreasing trend from west to East.(2) During 2000 to 2013, the ecological vulnerability of the study area showed a decreasing trend with increased area of slight and mild vulnerability and decreased area of moderate and severe vulnerability.(3) Land use, climate change and human activities are the important factors that affect the spatial-temporal distribution patterns of ecological vulnerability. The research results can provide data supports for deciding the protection and precise restoration of the fragile ecological environment in Nanling Mountain.
