宿淮矿区采煤塌陷水域对气温变化的影响

摘要：选取宿淮矿区采煤塌陷水域（宿州站点）和对比区域（阜阳站点）1960-2007年的逐月气温数据，采用线性倾向估计和对比分析等方法，研究了采煤塌陷水域对气温变化的影响。结果表明：采煤塌陷水域（宿州）近48a来春、秋、冬季和年平均气温均呈上升趋势，冬季的每10a气温增幅最大，达到0．58C／10a；气温年较差呈现减小趋势；1960～1990年代平均气温采煤塌陷水域（宿州）低于对比站点（阜阳）；2000-2007年，采煤塌陷水域（宿州）春、秋、冬季气温高于对比站点（阜阳），夏季气温低于对比站点（阜阳）。

The Effect of Coal Mining Subsided Water Area on Temperature Change in Suhuai Coal Mine

In order to analyze the effect of coal mining subsided water area on temperature change in Suhuai coal mine, monthly data about temperatures from 1960 to 2007 recorded by two weather stations were collected and investigated by linear trend estimation and comparative analysis methods. Results show that spring, autumn, winter and annual average temperatures are increasing in the last 48 yearsthe increase of winter temperature is particularly significant with a warming rate of 0. 58＇C/10a. Annual temperature range is decreasing~ Inter- decadal of temperature in coal mining subsided water area （suzhou） is lower than contrast site （fuyang） from 1960 to 1999. From 2000 to 2007,temperature of coal mining subsided water area （suzhou） in Spring and win- ter are higher than contrast site （fuyang）,in summer air temperature is lower than contrast site （fuvang）.
