摘要
[目的]探索基于形态学空间格局分析(MSPA)和生态保护重要性评价的市域生态网络构建方法,为市域生态网络规划与建设提供科学参考。[方法]以黑龙江省牡丹江市为例,采用MSPA分析结果拓扑叠加研究区生态保护重要性评价,综合得出生态源地;利用最小阻力模型提取研究区潜在生态廊道并结合重力模型进行重要度划分;从源地补充、廊道补充、增补踏脚石三方面进行生态网络结构优化。[结果]①根据MSPA分析结果,牡丹江市核心区域面积在景观类型中比例最高,为87.41%,其中林地为主要景观类型。②牡丹江市域内有主要生态源地10处,次要生态源地6处。③牡丹江市域内潜在重要生态廊道16条,一般生态廊道104条。④优化前生态网络闭合度(α指数)为0.53,优化后为0.66;网络连接数(γ指数)优化前为0.69,优化后为0.77,线点率(β指数)优化前为2.0,优化后为2.26。[结论]综合MSPA分析法和生态保护重要性评价法的生态网络构建方法运用,有助于生态网络的结构性和功能性提升。
[Objective]The construction method for an urban ecological network based on morphological spatial pattern analysis(MSPA)and ecological protection importance evaluation were studied in order to provide a scientific reference for the planning and construction of urban ecological network.[Methods]The importance of ecological protection at Mudanjiang City,Heilongjiang Province was evaluated using the topological superposition of MSPA analysis results,and the birth source area was comprehensively obtained.We used the minimum resistance model to extract potential ecological corridors in the study area,and combined them with gravity models for importance classification.We optimized the ecological network structure from three aspects:source supplement,corridor supplement,and stepping stone supplement.[Results]①The MSPA analysis results showed that the core area of Mudanjiang City had the highest proportion of landscape types(accounting for 87.41%)and that forest land was the main landscape type.②There were 10 main ecological sources and six secondary ecological sources at Mudanjiang City.③There were 16 potential important ecological corridors and 104 general ecological corridors at Mudanjiang City.④Ecological network closure(αindex)before optimization was 0.53,and 0.66 after optimization.Number of network connections(γindex)was 0.69 before optimization,and 0.77 after optimization.Line point rate(βindex)was 2.0 before optimization,and 2.26 after optimization.[Conclusion]The application of the comprehensive MSPA analysis method and the ecological protection importance evaluation method in ecological network construction can help improve the structure and functionality of the ecological network.
