| Abstract (English): |
Based on the observation data of nine meteorological stations in Yuxi from 1961 to 2020, this paper analyzed the spatial and temporal distribution of climatic potential productivity（CPU） in Yuxi Region during the past 60 years, and found out the main factors related to climatic potential productivity. Using the formula of climate capacity, the climate capacity of climate resources to human society and the relative surplus rate of different consumption in Yuxi Region was estimated under the current climate potential productivity. The results showed that the distribution of climatic potential productivity in Yuxi Region was consistent with the topography, and the region with large elevation difference had small climatic potential productivity. In recent 60 years, the climatic potential productivity had decreased, yet not significantly. The inter-annual fluctuation of climatic potential productivity was distinct, which was mostly affected by annual precipitation. Although the capacity of climate carrying capacity could meet the food needs of different consumption levels in the region, there were significant differences among counties and districts in Yuxi. Therefore, it was necessary to optimize the climate carrying capacity of Yuxi region and improve land yield. [ABSTRACT FROM AUTHOR] |
| Abstract (Chinese): |
利用1961—2020年玉溪9个气象站的观测数据，分析玉溪地区近60年的气候生产潜力时空分布情况，同时找出限制气候生产潜力的主要因子。利用气候承载力计算公式，估算玉溪地区在当前气候生产潜力下气候资源对人类社会的气候承载力和不同消费水平下的相对剩余率。结果表明：玉溪地区气候生产潜力分布与地势相符，地势高差较大的地区气候生产潜力较小。近60年气候生产潜力减少，但减少趋势不显著，气候生产潜力年际波动较大，其核心限制因素是年降水量。虽然气候承载力的容量能够满足该地区不同消费水平的粮食需求，但玉溪各县区呈现出明显差异性，因此需要优化玉溪地区气候承载力，提高土地出产率。 [ABSTRACT FROM AUTHOR] |
