| 摘要: |
| 以河源市为研究范围，采用形态学空间分析（MSPA）和最小累积阻力模型（MCR）构建河
源市生态网络并提出优化策略。结果表明：河源市现状 17 个生态源地较集中分布，主要分布在河源市西
部、西北部和南部，东北部和东部出现生态源地盲区；整体的生态阻力呈现西北和东南部高于西南和东
北部的一种趋势，生成 136 条潜在生态廊道以网状分布，且南北部生态廊道的分布明显比东西部和中部
的生态廊道密集；识别出重要生态廊道 78 条、一般生态廊道 58 条与 17 个生态源地共同组成河源市生态
网络，针对目前的东北部和东部生态源地和生态廊道空缺提出保护重要生态源地、保护和建设生态廊道
和“踏脚石”建设三位一体的优化策略。 |

| Abstract: |
| Using Heyuan city as the research example， the ecological network of Heyuan city was
constructed through methods of morphological spatial analysis（MSPA）and the minimum cumulative resistance
model（MCR）, as well as proposed optimization strategies. The results show that the current 17 ecological
source areas in Heyuan city are relatively concentrated, mainly in the west, northwest, and south of Heyuan city,
and there are blank areas of ecological source areas in the northeast and east; the overall ecological resistance is in
the northwest and there is a trend that the southeast is higher than the southwest and northeast, and 136 potential
ecological corridors are distributed in a network, and the distribution of the ecological corridors in the north and
south is denser than that in the east and the middle; the 78 important ecological corridors, 58 general ecological
corridors, and 17 ecological source areas together build the current ecological network of Heyuan city. The
optimization strategy of protecting important ecological sources, protecting and building ecological corridors and
"stepping stones" is put forward. |
