| 中文摘要 |
| 为构建河南省生态安全格局以支撑区域生态保护与可持续发展,综合运用形态学空间格局分析法、电路理论及空间句法对河南省景观要素进行系统分析. 通过确定生态源地、廊道、夹点和障碍点等关键要素,并评估生态网络的形态结构特征,明确需优先修复的关键性空间. 结果表明:①河南省景观类型总面积达32 066 km2,占研究区面积的19.20%,其中核心区面积为23 095 km2,占比为13.83%;当面积阈值≥3 km2时,共识别出380个生态源地,生态源地面积占研究区总面积的12.96%,主要集中于西部、中部和南部地区. ②基于电路理论提取出1 139条生态廊道,总长度达18 206.68 km,其中包括重要廊道504条、次重要廊道403条和一般廊道232条,同时识别出316处生态夹点(分布于廊道与源地交界处)和290处生态障碍点(沿廊道分布). ③建议优先修复北部及东部的109处生态障碍点,修复面积总计1 387.19 km2. ④最终构建了“一带、二纵、三屏、四廊、多点”的生态安全格局. 该格局及其关键要素充分反映了河南省生态系统的实际特征,提出的修复策略为区域生态保护与可持续发展提供了科学依据和实践指导. |

| To construct an ecological security pattern for Henan Province to support regional ecological protection and sustainable development, a comprehensive analysis of the landscape elements in Henan Province was conducted using morphological spatial pattern analysis (MSPA), circuit theory, and space syntax. By identifying key elements such as ecological sources, corridors, pinch points, and obstacles and evaluating the morphological structure characteristics of the ecological network, critical spaces requiring priority restoration were determined. The results indicated that: ① The total area of landscape types in Henan Province was 32 066 km2, accounting for 19.20% of the study area, with core areas covering 23 095 km2, or 13.83%. When the area threshold was ≥3 km2, 380 ecological sources were identified, occupying 12.96% of the total study area, mainly concentrated in the western, central, and southern regions. ② Based on circuit theory, 1 139 ecological corridors were extracted, with a total length of 18 206.68 km, including 504 important, 403 secondary important, and 232 general corridors. Additionally, 316 ecological pinch points (located at the junctions of corridors and sources) and 290 ecological obstacles (distributed along corridors) were identified. ③ It is recommended to prioritize the restoration of 109 ecological obstacles in the northern and eastern regions, with a total restoration area of 1 387.19 km2. ④ Ultimately, an ecological security pattern of “one belt, two verticals, three screens, four corridors, and multiple nodes” was constructed. This pattern and its key elements fully reflect the actual characteristics of Henan Province's ecosystem, and the proposed restoration strategies provide scientific basis and practical guidance for regional ecological protection and sustainable development. |
