| 摘 要： | 基于地表能量平衡的基本理论,结合吉林西部实际资料,建立了吉林西部蒸散量估算的遥感模型.采用实测资料利用上述模型计算得到吉林西部地区的月、年蒸发量.经检验,计算值与实测值基本接近,绝大部分月份蒸散量的相对误差都在10%以内.该模型对任意地表类型及任何月份的蒸散量估算都具有较高的精度.

| Abstract: | With the rapid development of remote sensing technology, it becomes promising for the estimation of regional evapotranspiration over heterogeneous land surface. Remote sensing based regional evapotranspiration study has also become an imporam Subject. Based on the surface energy balance theory and in association of the real world data from the west of Jilin Province, the authors established a remote sensing model for estimating evapotranspiration for the study area. Furthermore the authors preyed the validity of the remote sensing model using data measured on sites by weather observatories and stations. The model provides a new approach for studying eco-environmental problems in the west of Jilin Province. |
