| 摘要: |
| 作为中国改革开放的前沿阵地和南方林区的代表区域，东莞市的自然保护地面临一系列人地矛盾冲突。以东莞市为例，在基于土地覆被类型的传统人为干扰评价基础上，叠加坡位和地形起伏度2种地形因子，以三维视角评估人为干扰的空间分布强度，并结合空间自相关分析方法，评估自然保护地的保护现状和识别可能存在保护空缺的区域。结果表明：目前东莞市的自然保护地存在建设用地边界扩张倒逼自然保护地边界后退的风险，且现有自然保护地空间范围存在部分未与人为干扰冷点重叠的区域。在此基础上，进一步结合现状生态保护价值，提出东莞市自然保护地空间优化相关建议，即严控城镇开发边界，将东莞市南部具备自然保护地设立条件的人为干扰冷点区域纳入自然保护地范围，以期为强化区域生态屏障保护功能和优化自然保护地空间范围提供重要的参考依据。 |

| Abstract: |
| Dongguan City is at the forefront of China’s reform and opening up and a representative forest area in southern China, where the protected areas face a series of contradictions and conflicts between human and land. Taking Dongguan City as an example, this research superimposes the two topographic factors of slope position and topographic relief on the traditional human disturbance evaluation based on land cover types, evaluates the spatial distribution intensity of human disturbance from a three-dimensional perspective and, in combination with the spatial autocorrelation analysis method, evaluates the protection status of protected areas and identifies areas that may have protection gaps. Research results show that: there exists such a risk that the boundary expansion of construction lands may force the boundary of protected areas to retreat in Dongguan City, and there exist some areas not overlapped with areas featuring little human disturbance in the spatial scope of existing protected areas in Dongguan City. On this basis, the research, further combines with the current ecological protection value, puts forward relevant suggestions for the spatial optimization suggestions of protected areas in Dongguan City, such as strictly controlling the boundary of urban development and incorporating areas featuring little human disturbance that are suitable for the establishment of protected areas in the southern part of Dongguan City into the scope of protected areas, which can provide an important reference for strengthening the protection function of regional ecological barriers and optimizing the spatial scope of protected areas. |
