| 摘 要： | 应用河南赵口灌区的遥感影像数据,获得该区的NDVI、LST等影像指标。采用植被温度指数法,通过ENVI遥感影像处理软件,得到植被条件指数、温度条件指数和干旱指数(DI)。将研究区划分为5个干旱等级,根据DI指数制作赵口灌区干旱等级分类图,计算该时期土壤含水量。分析计算小麦各生育阶段作物需水量,与该阶段土壤含水量对比计算各种干旱类别区域的配水量。 |
| 关 键 词： | 遥感 植被温度指数法 干旱指数 |

| Abstract: | Using the remote sensing data of Zhaokou irrigation District,the NDVI,LST and the image index were gained.According to vegetation temperature index method,through ENVI remote sensing image processing software,vegetation condition index(IVC),temperature condition index(ITC) and drought index(DI) were obtained.The area was divided into five drought levels.According to DI index,the classification diagram of Zhaokou irrigation drought levels was constructed.The value of soil water content was calculated.Calculating water requirement of wheat in every growth stage,which was compared with soil water content to calculate water allotment of each area. |
| Keywords: | RS vegetation temperature index method drought index |
