摘要:

从资源丰富度、稳定度和保障度3个方面,分别选取了较有代表性的太阳总辐射、日照时数和有效日照天数3项量化因子,利用多指标评分法对中国陆地太阳能资源开发潜力进行了综合评价和分析。结果表明:①中国青藏高原大部、日一肃北部、新疆东部和内蒙中西部地区,太阳能资源极为丰富,最适于进行大规模光电开发;②日一肃中部、新疆、青海东部和南部、内蒙古中东部、东北西部、河北与宁夏北部、四川西部,太阳能资源比较丰富,也适于规模化的太阳能发电;③东北东部和北部、华北平原北部、黄上高原大部、青藏高原东南缘、云南大部、雷州半岛和海南岛,以及新疆北部,太阳能可小规模或季节性开发利用;④其余地区太阳能资源比较贫乏,规模性开发潜力低。

Abstract:

With rapid population growing and dramatic industrial economy developing, the world faces the dual challenges of massive energy requirements and environmental issuescaused by extensive fossil fuel depletion. One of the main candidates for faxing these challenges are renewable sources of energy (including solar, wind, biomass, geothermal, hydro,wave and tidal energies). Among these sources, solar energy comes at the top of the list due to its abundance, and more even distribution in nature than any other renewable energy types. However, analyses of China's solar energy potential so far have generally relied onclimatological empirical formula which is hard to spread and undeveloped drawing technique. Therefore, based on general solar radiation observations taken from 99 China's radiation stations and sunshine duration observations taken from 387 of China's 752 meteorological stations, this textcpunted average annual solar total radiation as the factor of abundance, sunshine duration as the factor of stabilization and available sunshine days(≥3 hours) as the factor of guarantee from the years 1995-2004. Using ArcGIS cartography software and the aforementioned data, the following text depicted a series of maps of mainland China's solar energy distribution. Then these maps were overlaid to present a more accurate picture of mainland China's solar energy potential. An analysis of these maps leads to the following conclusions. The greatest solar energy potential is in the Qingzang Plateau, Northern Gansu, Eastern Xinjiang and Mid-Western Inner Mongolia, where are the best locations for extensive solar energy utilization; solar energy potential in Xinjiang, Eastern Inner Mongolia, western part of Northeast Plain, Northern Hebei and Ningxia, Southeast Qinghai and Western Sichuan, is the second best, also perfect for solar energy development. In the areas of the northeast part of Northeast Plain, most parts of Loess Plateau, Yunnan and Hainan, Northern Huabei Plain, and Northern Xinjiang, solar energy potential is at average level. The other areas of mainland China have small solar energy potentials due to the lack of solar radiation.
