南澳县半个世纪以来的气候演变特征

Climate evolution of Nanao in the half-century

本文采用线性趋势分析、滑动平均等方法对南澳县1957-2006年间的气象资料进行气候演变特征分析,同时通过用同一种探测手段获得的资料对南澳县限制开发前后气象要素进行对比分析,得出气温有增暖的趋势,以冬季增温为主;降水多雨期和少雨期呈交替性变化;日照呈增多的趋势。结果表明:独天得厚的海岛优势和限制性的开发,岛上的气象要素变化基本上不受地域的影响,主要是受大背景气候趋势的影响。

The climate change of Naoao from 1957 to 2006 is analyzed based on the methods of linear trend analysis and moving average etc. At the same time, before and after restricted development in Naoao,the meteorological factors are made comparative analysis by using the same detecting method. We found that there was a warm trend in temperature,especially in winter. The rain period were less rain period were alternated, and sunshine showed a growing tendency.
