摘要
本项目开展自主研发的RSPCYWM模型系统已在我国华北地区作物生长过程监测和估产中大范围推广及应用，包括RSPCYWM模型的检验、作物生长发育期的生物量和产量估算；同时改进作物模型系统，加入RUBISCO酶限制的作物光合速率模块，作物冠层水分导度模块，以求更加真实地模拟作物的生产过程和对华北地区作物的估产，使监测和模拟精度达到95％以上。
The self-developed water-deficit crop yield estimate model system based on remote sensing and crop photosynthesis by the project （RSPCYWM）, has been used widely to monitor crop growing processes and to estimate crop yields in North China. The verification of RSPCYWM and estimation ofbiomass and yields were conducted. Meanwhile, the crop model system was improved,
