中国陆地生态信息空间化技术研究(Ⅱ)——太阳辐射要素

Study on spatialization technology of terrestrial eco-information in China(II): Solar radiation

论文以MTCLIM模型为基础,根据中国的实际情况,对模型的参数进行了优化与调整,建立了适合我国的基于温度、降水和相对湿度等因子的太阳总辐射计算模式。提出了太阳总辐射空间化的模式,即先参数化,然后采用合适的空间插值方法(论文中采用地统计学方法)实现空间化。同时鉴于逐日太阳总辐射空间化工作量庞大,提出了在计算月均日结果的基础之上,采用线性插值技术快速得到逐日太阳辐射值。从而得到了中国太阳总辐射的空间分布结果。

Based on MTCLIM Model,according to actual conditions of China,parameters of the model were optimized and adjusted and the model for calculating global solar radiation was set up based on temperature,precipitation and relative humidity in China.As for the proposed spatialization model of global solar radiation,parameterization should be done first and interpolation second.Considering the big workload of spatialization of daily global solar radiation,based on calculating monthly mean daily result,it is suggested to use liner interpolation technology to get a quick spatialization value of the daily global radiation.Finally,the spatial distribution of daily global radiation in China was generated.
