福建省太阳能资源模拟计算及评估

The Calculation and Assessment of Solar Resources in Fujian Province

根据复杂地形下太阳辐射的计算方法，建立了福建省不同时空尺度的太阳辐射的估算模式。基于100m-100m分辨率的高程模型数据，综合考虑了地形因子对太阳辐射的影响，实现了复杂地形下福建省太阳辐射的分布式模拟。利用福建省69个气象站1971年～2007年日照资料，计算了福建省范围内100m-100m分辨率1～12月太阳辐射的时空分布。结果表明，福建省年太阳总辐射主要在3800～5300MJ／m2之间，年太阳直接辐射在1800—2800MJ／m2之间，月太阳辐射介于464～594MJ／m2之间，6～8月为一年中辐射较高的3个月份。受地形及地表特征的影响，太阳辐射的高值区主要位于在福建东南部的莆田、泉州、厦门、漳州四市的沿海一带，年太阳总辐射超过4500MJ／m2，年太阳直接辐射超过2100MJ／m2，此外，位于福建北部的南平市的部分地区太阳辐射也相对较高。由此可见，福建省太阳辐射的高值区非常适宜于太阳能资源的开发与利用。

Based on calculating method of solar radiation over rugged terrains, solar radiation transmittance models for different temporal and spatial scales were established. Using the digital elevation model data of 100m ×100m resolution as input and giving an all sided consideration on factors influencing solar radiation, a distributed model for calculating solar radiation, over rugged terrains , in Fujian Province was established. In accordance with the monthly percentage of sunshine from 1971.01 to 2007.12 in Fujian, monthly solar radiation with the resolution of 100m×100m, over the generated. Result shows, annual global solar radiation in Fujian rugged terrains, in Fujian Province was province ranged from 3800 MJ/m2 to 5300MJ/m2, and annual direct solar radiation in Fujian province ranged from 1800 to 2800MJ/m2. Monthly variation of solar radiation, in Fujian Province, showed that monthly global solar radiation ranged from 464 MJ/m2 to 594MJ/m2,the radiationy in June,July and August is more than any other month,. Global solar radiation is more than 4500 MJ/m2 in coastal areas from Putian to Zhangzhou, and annual direct solar radiation is more than 2100 MJ/m2 in those areas. Besides, the solar radiation also very high in most areas of Nanping which lies in northwest of Fujian Province. Those areas, where solar radiation quantity high, is suitable for exploitation and utilization of solar energy resources.
