| 摘 要： | 文中利用NCAR区域气候模式REGCM2和荷兰WAGENINGEN农业大学的作物生长过程模式SUCROS在中国东部平原进行了作物 大气双向耦合的模拟试验。初步的研究结果表明 ,该双向耦合模拟试验 (R/S)能较好地描述大气和农作物间动态的基于生物过程的相互作用。R/S模拟试验不仅能真实合理地反映植物叶面积指数的逐日变化特征 ,更好地描述中国东部平原的陆面物理过程 ,而且改善了REGCM2对中国东部地区夏季降水和地面温度的数值模拟。该项研究对进一步认识和研究气候系统与陆地生态系统的相互作用具有一定的意义。 |

| Abstract: | The ecological system,as one of the vital factors to climate change,exerts impacton the earth at a full range of scales.In view of the fact that a draw back lies in employing climate models to simulate the effect of vegetation upon at mospheric circulation as a general practice,we propose a coupling model(R/S).A two-way coupling simulation from the NCAR's regional climate model REGCM2(called R-2 hereafter) and the SUCROS model for crop growth developed by the Wagening en Agricultural University,the Netherlands (both models,when in combination,denoted as R/S) are carried out on the interactions bet ween crops and at mosphere in Huang-Huai-Hai Plain.The experimental region(25-45°N,105-130°E) is in East China,with grid spacing of 60 km.Both models exchange information once a day.On a daily basis,the R-2 provides the SUCROS grid-points (in the box) with the total surface incident radiation,precipitation,maximal and minimal temperatures,mean vaporpressure and wind speed to drive its operation while the SUCROS furnishes the gridpoint LAI for the R-2. |
| Keywords: | Two-way coupling Air-vegetation interactions Regional climate simulation Huang-Huai-Hai Plain |
