1961—2007年海口市气候环境变化及其对城市发展的响应

基于海口市1961—2007年的气象资料以及1989—2007年的城市化水平，对海口市气候环境变化及其与城市化水平的关系进行了分析.结果表明：与1961—1990年相比，海口市1995—2007年气温呈明显的增高态势，年均增温0.93 ℃；而相对湿度则明显降低，年均湿度降低了3%；海口市年均气温、年均相对湿度与城市化水平分别呈显著和极显著相关，说明城市化较好地解释了近20年来海口市气候要素的变化.海口城市的发展，不仅改变了气候环境要素，而且影响了大气环境质量，使酸雨次数增加、年均酸雨pH值降低.

Climatope change and its relations with city development of Haikou City in 1961-2007.

Based on the 1961-2007 meteorological data of Haikou City and its urbanization level in 1989-2007, this paper studied the climatope change and its relations with city development of the City. In 1995-2007, the mean annual air temperature in Haikou had an obvious increase, with an increment of 093 ℃·a^-1,while the mean annual relative humidity decreased obviously, with a decrement of3% per year, compared with those in 1961-1990. Both the mean annual air temperature and the mean annual relative humidity had significant correlations with the urbanization level of Haikou, suggesting that urbanization could better explain the recent 20 years variation of climate elements in Haikou. The city development of Haikou not only changed the climatope elements, but also affected the airquality, making the frequency of acid rain increased, and the mean annual acid rain pH value decreased.
