| 摘 要： | 根据景观生态学相关理论, 应用地理信息系统(GIS)技术研究浙江省苍南县生态廊道空间布局与构建。在对研究区进行生态适宜性分析的基础上, 通过提取生态源地, 运用累积耗费距离模型构建了苍南县潜在的生态廊道, 并与现存生态廊道进行比较研究。结果表明:在苍南县东北部平原地区, 生态斑块数量和面积均较小, 斑块之间连接度较低, 景观破碎化程度较高; 道路和河流是境内主要的生态廊道, 廊道连通性较低, 其规模和服务范围均较小, 没有形成良好的生态网络。在西部、南部和西北部山区, 生境良好, 生态斑块面积较大, 但是分布不均。尤其是在中部和西部地区, 生态斑块数量较少, 斑块之间连接度低, 廊道连通性差。通过分析现存生态廊道诸多问题, 从道路廊道、河流廊道、绿带廊道出发, 优化和构建了研究区生态廊道, 实现生态廊道功能最大化的建设目标。

| Abstract: | On the basis of landscape ecology theories, the spatial layout and construction of ecological corridors in Cangnan County, Zhejiang Province were studied with GIS technology. In the context of regional ecological suitability analysis, the ecological source was identified and the potential ecological corridors were constructed through the cumulative cost distance model and compared with the existing ecological corridors. The results indicated that in the northeastern plains in Cangnan County, the number and area of ecological patches were small; connectivity among patches was low and landscape fragmentation was serious. As major ecological corridors characterized by small size and service area, roads and rivers had low connectivity among them and did not form a good ecological network. In the western, southern and northwestern mountains with good ecological habitats, the ecological patches were larger but unevenly distributed. Especially, in the central and western regions, the number of ecological patches was small; the connectivity among both patches and corridors was low. Through the analysis of the above problems, ecological corridors including roads, rivers and green belts in the research site were optimized and constructed to realize the maximum functions of ecological corridors. |
