| 中文摘要: |
| 以甘肃省为研究区，基于1990—2020年的高分辨率不透水表面数据，运用空间分析法、相关分析法和趋势分析法，全面分析甘肃省145个自然保护地与不透水表面面积之间的关系，对比揭示自然保护地内部和外部不透水表面的变化规律。结果表明：30年间甘肃省自然保护地内部的人类活动压力小于其外部，并且人类活动压力总体上随自然保护地面积的增加而增大；自然保护地内部和外部人类活动压力逐渐向高值区转移，高值区的保护地数量逐渐增加，自然保护地外部人类活动压力所在高值区的数量总体上高于内部；自然保护地内部和外部的人类活动压力呈线性增长趋势，人类活动压力在自然保护地内部的增长速率远低于外部。 |

| Taking Gansu as the research area， based on high resolution impervious surface data from 1990 to 2020， this study comprehensively analyzed the relationship between 145 nature reserves and impervious surfaces area in Gansu using spatial analysis， correlation analysis and trend analysis， and comparatively revealed the changing patterns of impervious surfaces inside and outside nature reserves. The results showed that over the 30 year period， the pressure from human activities inside nature reserves in Gansu was less than that outside. Overall， the pressure from human activities increased with the increase in area of nature reserves. The pressure from human activities both inside and outside nature reserves was gradually shifting to high value zone， and the amount of nature reserves in high value zone was gradually increasing. Generally， the amount of pressure from human activities in high value zone outside nature reserves was greater than that inside. Furthermore， the pressure from human activities exhibited a linear increase trend both inside and outside nature reserves， yet the growth rate inside was much lower than that outside. |
