| 中文摘要: |
| 利用ENVI软件，基于像元二分模型法的剑川县2013年和2021年冬季Landsat 8影像，结合归一植被指数，计算剑川县不同时期植被覆盖度，利用决策树分类方法获得2013年和2021年两个时期的植被覆盖动态变化特征。结果表明，8年来剑川县高覆盖度植被区域面积不断增加，生态环境得到不断改善。分析剑川县各乡镇生态特色，结果表明，剑川县文化底蕴深厚，具有较好的森林城市创建潜力。 |
| 英文摘要: |
| Using ENVI software, according to the pixel dichotomy model method for the 2013 and 2021 winter Landsat 8 images of Jianchuan County, combined with the normalized vegetation index, the vegetation coverage was calculated, and then the decision tree classification method was used to obtain the dynamic changes of vegetation coverage in the two periods.The results showed that the area of high coverage vegetation in Jianchuan County was increasing and the ecological environment was improving in the past eight years. The analysis of the ecological characteristics of various townships in Jianchuan County showed that Jianchuan County had a profound cultural heritage and good potential for creating forest city. |
