    摘要:

    以河南省冬小麥旱情遙感監(jiān)測(cè)為例,，利用MODIS/AQUA衛(wèi)星產(chǎn)品的歸一化植被指數(shù)（NDVI）,、增強(qiáng)型植被指數(shù)(EVI),、葉面積指數(shù)(LAI)和地表溫度(ST)數(shù)據(jù),，分析了NDVI—ST和EVI—ST的特征空間,，發(fā)現(xiàn)NDVI—ST和EVI—ST的特征空間具有雙拋物線型特征,。將其與三角形NDVI—ST、EVI—ST及LAI—ST特征空間進(jìn)行對(duì)比分析,，并將得到的溫度植被干旱指數(shù)（TVDI）數(shù)據(jù)與土壤濕度進(jìn)行相關(guān)性分析,，揭示雙拋物線型NDVI—ST特征空間能更好地反映地表10cm土壤水分狀況,。以雙拋物線型NDVI—ST特征空間得到的TVDI作為旱情遙感監(jiān)測(cè)指標(biāo)，評(píng)估了2011—02—26~2011—05—16河南省冬小麥旱情,，并與當(dāng)?shù)貧庀笳窘涤陻?shù)據(jù)對(duì)比,，揭示了2011年春天河南省旱情發(fā)展的總體時(shí)空特點(diǎn)。

    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.
