利用三江源地区18个气象台站1961年以来观测的日、旬、月和年气温、日照时数、日照百分率以及玉树站观测的太阳辐射资料,根据气候学原理,在充分考虑天文辐射、大气透明系数,日照百分率等影响太阳辐射因子的基础上,计算出三江源地区的太阳能资源,然后以年太阳总辐射量作为一级(主导)区划指标,以日平均气温稳定通过0℃(日最高气温达10～15℃)以上期间的日数(利用佳期)作为二级区域指标进行分区,对三江源地区9个不同类型的太阳能资源区进行分区评述,同时计算了三江源地区粮食光合生产潜力和气候生产潜力,结果表明农作物生长期光合生产潜力为26846.4kg/hm2;光温生产潜力为11812.4kg/hm2;气候生产潜力为9449.9kg/hm2,与1997年-2006年实际年平均粮食产量3327.0kg/hm2相比;只占气候生产潜力的35%,说明三江源地区粮食生产潜力的提升空间还很大,最后得出:三江源地区由于太阳能资源丰富、土地利用条件优越、电网容量与架构理想、电价水平较低、交通设施便利、光伏产业链完整、太阳能利用市场和国家政策扶持力度较大等优越条件而开发利用潜力巨大。
Based on the daily, ten-day, monthly and yearly temperatures, the sunshine hours, the percentage of sunshine and the observed solar radiation data of 18 meteorological stations in the Three River Source Region since 1961, according to climatological principles, taking full account of astronomical radiation, Coefficient and sunshine percentage on the basis of the solar radiation factors to calculate the solar energy resources in the Three Rivers region, and then take the annual total solar radiation as the first-level (dominant) zoning indicators, the daily average temperature through 0 ℃ (daily maximum temperature Up to 10 ~ 15 ℃) were used as the second-level regional indexes to divide and review nine different types of solar energy resources in the Three River Source Region. Meanwhile, the potential of photosynthetic production in the Three-River Source Region and the climate The results showed that the photosynthetic potential for crop growth was 26846.4kg / hm2, the potential for light and temperature production was 11812.4kg / hm2, and the potential for climate productivity was 9449.9kg / hm2. Compared with the actual annual average grain yield of 3327.0kg / hm2; only account for 35% of the potential of climate production, indicating that there is still plenty of room for improvement in the potential for food production in the Three River Source Region. Finally, Due to abundant solar energy resources, favorable conditions for land use, power grid capacity and infrastructure ideal, low price level, convenient transportation facilities, a complete industrial chain of photovoltaic, solar energy market and national policy support and other favorable conditions and greater exploitation potential.
