- 摘要:
- 通过利用肇源县2008~2010年三景同期TM影像数据，使用ERDAS软件首先提取植被指数（NDVI），根据像元二分法利用ERDAS的建模工具计算出肇源县的植被覆盖度，利用非监督分类方法对该县的植被覆盖度进行分类、赋色，最后得出3 a间肇源县植被覆盖度分类图，定量说明了其变化情况：肇源县农作物种植面积呈增加趋势，2009年较2008年增加了23 542 km2；但由于2010年水势较大减少了2 871 km2。研究表明该方法可用于平原区农作物种植面积变化及转换情况的研究，较传统解译的方法获取信息更迅速，能为政府宏观决策提供有利依据。
- Abstract:
- Utilizing the same period three-view TM image data in the three years of 2008，2009，2010 of Zhaoyuan county，the vegetation Index（NDVI）was extracted by using the ERDAS software，then using the modeling tools of ERDAS to calculate the vegetation coverage of Zhaoyuan county according to Pixel dichotomy.Finally，using the unsupervised classification to classify vegetation coverage and assigned to color，the three-year category graphics of vegetation coverage of Zhaoyuan county was obtained.It showed its quantitative changes like this：The vegetation coverage of Zhaoyuan county was increased as a whole tend，the planting proportion of crops in 2009 were 23 542.2 km2 more than 2008.But about 2 871.09 km2 in2010 were submerged as a result of higher water potential.It also showed that the method could be used for study on changing and conversion of crop area in plain area，it could get information more quickly than traditional interpretation method，and could provide a favorable basis for the government to make macroeconomic policy.
