| 摘 要： | 作物单产估算是农作物估产中的关键技术,也是作物估产的难点之一.遥感技术凭借其宏观、及时和动态等特点已在农作物产量估算中占据着极为重要的地位,运用遥感信息建模估算作物产量已成为区域作物估产的必然要求.在总结农作物单产遥感估算模型研究成果的基础上,将作物单产遥感估算方法划分为四种模式加以详细阐述,分析了用于单产建模的遥感数据源的多元化趋势,讨论了如何有效验证模型估算精度的问题,最后对作物单产遥感估算模型今后的发展趋势作了展望. |

| Abstract: | The estimation of crop yield per unit area is not only the key technology,but also one of the difficulties for crop production estimation.Remote sensing is playing an increasingly important role in crop yield estimation with its macroscopical,real-time and dynamical dominance.As a result,it will become necessary to use the remote sensing information to construct crop yield models for crop yield estimation on large area scale.On the basis of summarizing the researches of crop yield estimating models at home and abroad,the paper divided crop yield models into four patterns,and expatiated on them respectively.Then,the paper analyzed the diversiform selective tendency of remote sensing data sources,which should extremely meet the need of constructing crop yield models.How to effectively valid the estimating precision of crop yield models was also discussed.Finally,the paper made the forecast for the development tendency of crop yield models. |
