中文摘要:以河南省冬小麦旱情遥感监测为例,利用MODIS/AQUA卫星产品的归一化植被指数(NDVI)、增强型植被指数(EVI)、叶面积指数(LAI)和地表温度(ST)数据,分析了NDVI—ST和EVI—ST的特征空间,发现NDVI—ST和EVI—ST的特征空间具有双抛物线型特征。将其与三角形NDVI—ST、EVI—ST及LAI—ST特征空间进行对比分析,并将得到的温度植被干旱指数(TVDI)数据与土壤湿度进行相关性分析,揭示双抛物线型NDVI—ST特征空间能更好地反映地表10cm土壤水分状况。以双抛物线型NDVI—ST特征空间得到的TVDI作为旱情遥感监测指标,评估了2011—02—26~2011—05—16河南省冬小麦旱情,并与当地气象站降雨数据对比,揭示了2011年春天河南省旱情发展的总体时空特点。

Abstract:Take the drought remote sensing for winter wheat in He’nan province as an example, the normalized difference vegetation index (NDVI), enhanced vegetation index (EVI), leaf area index (LAI) and land surface temperature (ST) data from MODIS/AQUA were applied to analyze NDVI—ST space and EVI—ST space. It was discovered that NDVI—ST and EVI—ST spaces were double parabola as compared with NDVI—ST, EVI—ST and LAI—ST triangle or trapezoidal space. The relationship between TVDI and soil moisture was analyzed with the obtained TVDI derived from the spaces. The results show that the NDVI—ST double parabola space is better than the others to reflect the 10cm-depth soil moisture. Based on the TVDI obtained from the NDVI-ST double parabola space, the drought situation in He’nan province, from February 26, 2011 to May 16, 2011 was evaluated. Compared with the raining data observed by local weather stations, the general spatio-temporal features of the drought situation of winter wheat in He’nan in the spring of 2011 was revealed.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
