摘要
以辽宁沿海经济带为研究对象,利用1997—2008年辽宁沿海各城市的城市化和气候指标,运用线性拟合、主成分分析方法探索城市化对气候的影响。结果表明,除盘锦和大连的气温在城市化影响下呈现微弱的下降趋势外,其他各地的年均温和年降水量均随着城市化进程的发展呈现波动性上升趋势。城市规模、产业结构合理水平、下垫面变化和城市环境共同构成葫芦岛、锦州、营口和大连城市气候变化的主要因素,而在盘锦和丹东,城市规模和城市环境是第一主成分,产业结构合理水平和下垫面变化是第二主成分。在未来的发展过程中,辽宁沿海经济带应控制人口数量,合理调整产业结构,减少污染物排放,增加绿地面积,从而协调城市化发展与气候之间的关系。
The coastal economic belt of Liaoning Province as the research object, using 1997 - 2008 Liaoning each city＇s urbanization and climate indicators, using linear fitting, principal component analysis method, explored the influence of urbanization on climate. The results showed that in addition to the temperature and Dalian merchant under the influence of urbanization present faint dropped the trend, other parts of the average annum pre- cipitation were mild with the development of urbanization process present volatility up trend. The size of city, industrial structure reasonable level, the underlying surface change and urban environment together constituted the Huludao, Jinzhou, Yingkou and Dalian City the main factors of climate change. In the future, Liaoning Province should control the population, and rationally adjust the industrial structure, so as to coordinate the development of urbanization and the relationship between the climate.
