| 自然保护地在维护国家生态安全中居于首要地位。利用遥感技术识别、诊断自然保护地人类活动空间分布和动态变化，及时预警自然保护地生态风险，可以为自然保护地管理工作提供技术支撑。基于 2020 年 GF-1、GF-2、GF-6、ZY-3、ZY-02C 高分系列遥感影像数据，解译提取广东省 94 处国家级自然保护地的人类活动变化图斑，探讨人类活动对自然保护地的影响。结果表明：（1）监测到人类活动变化的共有 57 处自然保护地，涉及变化斑块 272 个 , 以森林采伐和其它活动为主，总面积 770.25 hm2, 占自然保护地总面积的 0.08%。（2）不同类型自然保护地的人类活动强度不同，森林公园人类活动强度较强 , 其次为地质公园、湿地公园、风景名胜区和自然保护区 , 海洋公园和石漠公园人类活动强度较弱。（3）人类活动对保护地影响程度总体不明显。94 个国家级自然保护地的 NRHI 数值范围为 0 ~ 0.000 3，影响程度一般和轻微的保护地有 50 处，超过自然保护地总数的一半。 |

| Abstract: |
| Abstract Protection and development of nature protection have become increasingly prominent .The use of remote sensing technology to identify and diagnose dynamic changes of spatial distribution of human activities on nature reserves, early warning ecological risks of natural protection. It can be protected for conservation management for monitoring the provision of technical support. Based on high resolution satellite image of GF-1、 GF-2、GF-6、ZY-3、ZY-02C in 2020, the information of human land use activities on 94 national nature reserves in Guangdong Province was extracted to study the impact of human activities on nature protection.The results showed: 1.There are 57 national nature protection monitoring existed human activity centered on forest logging and other activities. It included 272 objects and 770.25 hm2, representing about 0.08% of the total area of national nature protection. 2.Different nature protection types of interference on human activities was different. It showed forest parks were strongest, followed by geological park, wetland park, scenic areas and nature reserves and rocky parks and ocean parks were weak. 3.The impact of human activity in general was not obvious and the values ranged from 0 to 0.000 3.There were 50 nature protection were common and slight , beyond half of the total number of natural protected areas. |
