中文摘要	依据宁夏中部干旱带同心县、盐池县等10个代表性气象台站36年(19752010年)逐旬气温、降水资料,基于Miami模型和Thornthwaite Memorial模型对宁夏中部干旱带19752006年间草地生产潜力作估算,并分析其变化规律,旨在为改良草地、植被恢复提供理论依据。结果表明:宁夏中部干旱带气候具有向暖干化变化的趋势,草地气候生产潜力年际变化范围为2668.56~7499.53 kg?hm~(-2)?a~(-1),气候生产潜力较大。当最高温度每升高或降低1℃,草地气候生产潜力增加或降低58.68 kg? hm~(-2)?a~(-1);年降水量每增加或降低1 mm,草地气候生产潜力增加或降低18.64 kg?hm~(-2)?a~(-1)。宁夏中部干旱带各区域年降水量与气候生产潜力相关系数为0.984?0.997,成极显著线性相关,而年均气温与气候生产潜力无显著相关性。在进行天然草地补种植物时,应考虑该地的自然承受力,即天然草地气候生产潜力。
英文摘要	The annual potential productivity of grassland in the middle arid zone of Ningxia during 1975 to 2006 was estimated according to the ten-day period temperature and precipitation of these years (19752010) recorded by 10 meteorological observatories using Miami model and Thornthwaite Memorial model. The objects were to analyze the change regulation of the potential climatic productivity and provide a theoretical basis for improving grassland and increasing vegetation. Results showed that the climate in the middle arid zone of Ningxia had a change tendency toward "warm dry". The inter-annual variation range of the grassland potential climatic productivity was 2668. 56?7499.53 kg?hm~(-2)?a~(-1) and the potentiality was large. The grassland potential climatic productivity increased or decreased 58.68 kg?hm~(-2)?a~(-1) with the maximum temperature increasing or decreasing 1℃. The grassland potential climatic productivity increased or decreased 18.64 kg?hm~(-2)?a~(-1) with the annual precipitation increasing or decreasing 1 mm. The annual precipitation and potential climatic productivity in the middle arid zone of Ningxia had an extremely significant linear correlation and the correlation coefficient was 0.984?0.997, whereas the average annual temperature and potential climatic productivity did not have a significant correlation. Therefore, the natural tolerance, namely potential climatic productivity of the natural grassland of the area, should be considered when planting.
