摘要
通过选取景观格局指数分析保护区内外的景观格局特征,研究了贵州湄潭百面水省级自然保护区的建立对保护区外产生的影响。研究结果表明:1990—2020年,在百面水省级自然保护区与10 km邻近区内,森林和农田为土地利用类型的主体,且保护区内外不透水面面积呈逐渐增加趋势;保护区的边缘密度、最大斑块指数、景观形状指数总体表现为下降趋势,保护区的平均斑块面积、景观破碎化指数、聚合度指数总体表现为上升趋势;1km邻近区的景观破碎化程度高于保护区而低于2~10km邻近区。由此可得,百面水省级自然保护区产生了正面影响的溢出效应,影响距离为保护区外1 km。
The impact of establishing of the Meitan Baimianshui Provincial Nature Reserve in Guizhou on the outside of the reserve was studied by analyzing the landscape pattern characteristics inside and outside the reserve through the selection of landscape pattern indexes.The results show that from 1990 to 2020,forests and farmland were the main land use types in the reserve and the 10 km adjacent area,and the area of impervious surfaces inside and outside the reserve gradually increased.The edge density,maximum patch index and landscape shape index of the reserve showed a downward trend,while the average patch area,landscape fragmentation index and aggregation index of the reserve showed an upward trend.The degree of landscape fragmentation in the 1 km adjacent area was higher than that in the reserve and lower than that in the 2~10 km adjacent area.In summary,the Baimianshui Provincial Nature Reserve has produced a positive spillover effect,with an impact distance of 1 km outside the reserve.
