摘要:

随着全球气温变暖和高温事件的频繁出现,水稻遭受高温影响的概率也随之增加。稻田气温是研究水稻遭受高温热害及其影响的数据基础。因此,大范围地反演稻田气温,有助于相关部门短时间内获取大范围的稻田气温数据并进行水稻高温热害的研究和决策部署。本文利用MOD09A1 8天合成数据对安徽省水稻种植区域提取,水稻种植区内的自动气象站气温数据与MOD11A1、MYD11A1 4个LST值进行多元逐步回归,得到遥感估算最高气温和平均气温方程最优,R2分别为0.728和0.825,均方根误差分别为(RSME)2.21、1.54,平均绝对误差(MEA)分别为1.73、1.15,最终完成基于卫星遥感信息和自动气象站气温数据反演稻田气温的方法的开发。将该方法应用于2017年安徽省水稻种植区的提取和气温的反演得到了很好的应用。

Abstract:

With the global warming and frequent occurrence of high temperature events, the probability of rice being affected by high temperatures increases. Rice field temperature is the foundation for studying the high temperature heat damage and its impact on rice. Therefore, the wide-scale inversion of rice field temperature could help relevant departments set up a wide-range rice field temperature data in a short time and carry out research on rice high temperature heat damage and decision making. In this study, the 8-day synthetic data of MOD09A1 was used to extract rice planting areas in Anhui Province. Then the temperature of the AWS (automatic weather station) in the rice planting area and the four LST values such as MOD11A1 and MYD11A1 were used for multiple stepwise regression. The optimal equation for estimating the maximum and average temperature from remote sensing data was obtained, with the R2 of 0.728 and 0.825, root mean square errors (RSME) of 2.21 and 1.54, and mean absolute errors (MEA) of 1.73 and 1.15, respectively. Finally, the method of inverting rice field air temperature based on satellite remote sensing information and AWS air temperature data was developed. The method was well applied in the extraction of rice planting areas and the inversion of final temperature in Anhui Province in 2017.
