| 摘 要： | 选择同一区域的TM与SPOT5数据,分别提取农田防护林与土地利用数据,分析不同空间分辨率数据对防护林数量及防护林景观评价指标的影响.结果表明,从数量值上来看,两者间林带长度的相对误差为7.5％,林带条数的相对误差为7.9％;从景观指标来看,带斑比基本不受数据源的影响,不同数据源的土地利用数据对连接度与优势度的影响较大,...

| Abstract: | Farmland shelterbelt and land use data were extracted from TM and SPOT5 data of the same region respectively.The impacts of data at different spatial resolutions on the assessment of shelterbelt quantity and landscape indexes were analyzed.Result showed that the relative errors in length and quantity of shelterbelt assessed by the two data sources were 7.5% and 7.9% respectively.Different data sources had little impact on ratio of belt to patch,while land use data from different data sources had a big influence on connectivity and dominance of shelterbelt network,with relative errors of 16% and 22% respectively.Shelterbelt and land use data from different data sources both had great influence on degree of circularity,so this index was the most sensitive to different data sources. |
