    摘要:

    随着社会经济快速发展,风景名胜区人类活动日益增强,往往带来景观格局变化等潜在威胁。为揭示景观格局与人类活动强度的响应关系,识别二者耦合作用形成的生态环境破碎区域,以金佛山国家级风景名胜区为例,基于2000年、2010年、2020年三期土地利用数据,通过构建人类活动强度模型及景观格局指数计算,对金佛山国家级风景名胜区景观时空变化进行定量分析,同时利用空间自相关分析,探索人类活动强度与景观格局在空间上的响应关联,进而叠加耦合出人地矛盾突出区域,作为潜在的重点关注区域。研究结果表明:自2000年以来,金佛山国家级风景名胜区景观格局发生明显变化,建设用地面积持续扩张,人类活动干扰增多,景观破碎度增加,景观异质性增强;近20年来人类活动强度高值区域面积逐年扩大且分布于低海拔区域,聚集在研究区域的北部三泉镇及南部金山镇等村镇聚落,高聚类区主要为建设用地与耕地区域;人类活动强度与景观格局变化存在显著的空间依赖性,呈现出较强烈的空间相关性,在空间分布中变化具有高度的一致性;金佛山风景名胜区人类活动强度与景观格局指数耦合的人地矛盾突出区域在空间分布中呈围绕南部及北部村镇扩张趋势。

    Abstract:

    With rapid socio-economic development, human activities in scenic areas are increasing, often bringing potential threats such as changes in landscape patterns. In order to reveal the response relationship between landscape patterns and human activity intensity and identify the ecological environment fragmentation areas formed by the coupling of the two, this paper takes the Jinfo Mountain National Scenic Area as an example. It quantitatively analyzes the spatial and temporal changes of the landscape in Jinfo Mountain National Scenic Area by constructing a model of human activity intensity and calculating the landscape pattern index based on the land use data of three periods in 2000, 2010, and 2020. At the same time, spatial autocorrelation analysis was used to explore the spatial response association between human activity intensity and landscape pattern and then superimposed and coupled the areas with major human-land conflicts as potential key areas of concern. The study resultsshow that the landscape pattern of Jinfo Mountain National Scenic Area has changed significantly since 2000, with a continuous expansion of the construction land area, increased human activity interference, increased landscape fragmentation, and enhanced landscape heterogeneity.In the past 20 years, the area of the high value of human activity intensity has expanded year by year. It is distributed in the low elevation area, gathering in the villages and towns of Sanquan Town in the north and Jinshan Town in the south of the study area. The high clustering areas are mainly construction land and cultivated land areas. The intensity of human activities and landscape pattern changes have a significant spatial dependence, showing a solid spatial correlation and a high degree of consistency in spatial distribution. The coupling of human activity intensity and landscape pattern index in Jinfo Mountain National Scenic Area shows that the regions with major human land conflicts are expanding around villages and towns in the south and north in spatial distribution.
