基于生态敏感性的自然生态空间管制分区研究——以山东烟台栖霞市为例

Study on Natural Ecological Space Control Zoning Based on Ecological Sensitivity——Taking Qixia City in Yantai City in Shandong Province as an Example

摘要:

科学划定自然生态空间并制定相应管制措施，是国土空间规划的重要内容，也是新时期生态文明建设的需求。本文以山东烟台栖霞市为研究对象，通过生态敏感性综合评价与经济林支柱产业的协同分析，确定栖霞市自然生态空间分区和相关管制规则。其中高度重要敏感区面积24 247 hm2，占全市自然生态空间的45.97%；中度重要敏感区面积18 129 hm2，占全市自然生态空间的34.37%；低度重要敏感区面积10 375 hm2，占全市自然生态空间的19.67%。高度重要敏感区以森林生态系统保护为核心，实施严格的人类活动管控，禁止扩大区域内经济林的种植规模；中度重要敏感区重点优化农业用地布局，强化水土保持，在保障生态功能的前提下允许适度的经济林提质改造；低度重要敏感区则可在生态环境可承载范围内适度扩大经济林种植规模。本研究结合地方支柱产业，利用生态敏感性综合评价方法，聚焦县级尺度生态敏感性与经济林产业协同管制，可为进一步理解和划定生态空间提供参考与借鉴。

Abstract:

Scientifically demarcating natural ecological spaces and formulating corresponding regulatory measures are crucial components of national land space planning and essential for promoting ecological civilization in the new era. In this paper, taking Qixia city in Shandong province as an example, through comprehensive assessment of ecological sensitivity and a coordinated analysis of economic forest pillar industries, natural ecological space zoning and related regulatory rules have been identified. Highly sensitive areas cover 24247hm2, and account for 45.97% of total natural ecological space. Moderately sensitive areas cover 18129hm2, and account for 34.37% of total natural ecological space. Lowly sensitive areas cover 10375hm2, and account for19.67% of the total natural ecological space. The highly important and sensitive areas prioritize the protection of forest ecosystems, implement strict human activity control, and prohibit the expansion of the planting scale of economic forests within the region. Optimize the layout of agricultural land in moderately important sensitive areas, strengthen soil and water conservation, and allow for moderate economic forest upgrading while ensuring ecological functions. Low importance sensitive areas can moderately expand the scale of economic forest planting within the carrying capacity of the ecological environment. This study combines local pillar industries and uses the comprehensive evaluation method of ecological sensitivity to focus on the coordinated regulation of ecological sensitivity and economic forest industry at the county level. It can provide references and inspiration for further understanding and defining ecological spaces.
