城市化地区生态保护红线保护成效评估——以深圳为例
Evaluation of the effectiveness of protection of ecological conservation redline in land area of Shenzhen

摘要: 生态保护红线是一条国家层面的“生命线”,是实施生态空间用途管制的重要举措。目前我国已基本完成生态保护红线的划定工作,“严守”生态保护红线已成为当前生态环境保护工作重点。如何科学的评估生态保护红线保护成效,服务于生态保护红线监管,将成为普遍关注的热点问题之一。本研究以深圳市(不含深汕特别合作区)为研究区,按照国家对生态保护红线的“面积不减少、性质不改变、功能不降低”的监管要求,考虑严格监督管理和地方性等因素,构建管理成效评估指标体系;采用遥感解析、地面调查、空间运算和统计分析等方法获取数据,开展生态保护红线保护成效评估研究,分析保护成效提高及应用途径。结果显示,深圳市陆域生态保护红线的保护成效指数为81.16,处于中度好转状态,表明通过生态保护红线的划定与监管,深圳市陆域重要生态空间被有效保护;限制深圳市陆域生态保护红线保护成效较大的指标是人类活动影响面积、重点生物物种种数保护率、生态保护红线制度与落实。未来,提高城市化区域生态保护红线保护成效,应考虑扩大生态保护红线面积、控制人类活动及线性工程范围、积极修复海洋岸线、保护重要生物,切实落实生态保护红线制度;通过成效评估,可及时掌握和了解生态保护红线生态功能状况及动态变化,预警生态风险,提高生态保护红线管理、决策水平,成效评估结果可为生态保护与修复、红线优化布局、执法监督、生态补偿等多方面提供依据,亦可纳入生态文明建设考核,督促各地区自觉推进生态文明建设。Abstract: The ecological conservation redline is a national "lifeline" and an important measure to implement the control of ecological space use. At present, China has basically completed the delineation of ecological conservation redline, and strictly observing it has become the focus of current ecological protection work. How to scientifically evaluate the protection effectiveness of the ecological conservation redline and serve the supervision of the ecological conservation redline will become one of the hot issues of universal concern. The research area of this study is Shenzhen, China (excluding Shenzhen Shantou Special Cooperation Zone). According to the national regulatory requirements of "no reduction in area, no change in nature and no reduction in function" of the ecological conservation redline, considering the factors such as strict supervision and management and locality, we constructed an evaluation index system for the management effectiveness of the ecological conservation redline in the terrestrial area of Shenzhen. Using remote sensing analysis, ground survey, spatial operation and statistical analysis to obtain data, we carried out an evaluation of protection effectiveness of the ecological conservation redline in the terrestrial area of Shenzhen, and analyzed the improvement of protection effectiveness and application ways. The results showed that the protection effectiveness index of the ecological conservation redline in the terrestrial area of Shenzhen was 81.16, which was in a moderately improved state. It shows that through the delineation and supervision of ecological conservation redline, indicating that through the delimitation and supervision of the ecological conservation redline, Shenzhen's important land ecological space was effectively protected. The indicators limiting the effectiveness of conservation are the area affected by human activities, number and conservation rate of key biological species, and the establishment and implementation of the ecological conservation redline. In the future, to improve the effectiveness of ecological conservation redline protection in urbanized areas, consideration should be given to expanding the area of ecological conservation redline, controlling human activities and linear ranges, actively repairing shorelines, protecting important organisms, and effectively implementing the ecological conservation redline system. Through the assessment, the ecological function status and dynamic changes of the ecological conservation redline can be grasped and understood in time, the ecological risks can be warned, and the management and decision-making level of the ecological conservation redline can be improved. The results of effectiveness evaluation can provide a basis for ecological protection and restoration, optimal layout of red line, law enforcement supervision, ecological compensation. It can also be included in the assessment of ecological civilization construction and urge all regions to consciously promote the construction of ecological civilization.
