| 摘 要： | 本文选择徐州市沛县地区作为研究区,运用支持向量机（SVM）对研究区多时相TM/ETM＋遥感影像进行土地覆盖分类,取得了比较满意的分类精度。在此基础上,结合景观生态学,从定性和定量两个角度对研究区近10年来的土地覆盖变化和景观生态格局变化作了分析,结果能够较好地反映研究区近年来的发展状况。最后根据研究成果,对研究区的发展提出一些有效性建议,以期能够对研究区快速、可持续的发展提供科学依据。

| Abstract: | Pei County in Xuzhou city was chosen as the study area in this paper.Support Vector Machine（SVM） was used to classify the multi-temporal Landsat TM/ETM＋ images.And the accuracies were satisfied.Then,combining the landscape ecology,land cover change and landscape ecology pattern change were also studied using quantitative and qualitative analysis methods.The results generally reflect the development condition of the study area.The given advices could effectively apply for sustainable development and the ecological environment process analysis by scientific evidences. |
