摘　　要：本文通过分析 NOAA- AVHRR数据 ,对研究区冬小麦各生育期的归一化植被指数 ( NDVI)进行计算 ,表明随冬小麦生育期发展 NDVI值呈现两头低 ,中间高的情形 ,这与冬小麦生长发育状况相一致 ,也即与冬小麦群体光合作用的响应。通过理论探讨进一步分析了NDVI与植被光合速率的关系 ,表明其存在某种程度的正相关。由此可更好地为从遥感信息建立估测植被生物量的机理模型提供依据。In the paper,the NDVI from remote sensing information in the study regional area was calculated.The result showed that the two sides of NDVI crave were low and middle site of crave was high.This result was same as the characteristic of winter wheat development conditions,and also response to the character of wheat winter photosynthesis, the relationship between the NDVI and photosynthesis was discussed,and this gave further understand to establish the biomass estimating model.
