煤矿矸石山绿化造林的小气候效应

对兴隆庄煤矿恢复植被23a的绿化矸石山小环境的气温、空气相对湿度和土壤温度进行了实证研究。结果表明:矸石山绿化造林后,在生长季4、7、8、9月份小环境的气温和土壤温度有明显的降低,矸石山的气温和土壤温度平均降低了2.8℃和5.0℃,在10月底小环境的气温和土壤温度有小幅度的升高,平均升高幅度分别为0.6℃和0.4℃。绿化造林提高了小环境空气相对湿度,平均增加空气相对湿度7.1%。 Temperature,air relative humidity and soil temperature were investigated in forested coal waste piles and bare coal waste piles of Xinglong coal mine the vegetation of which has been restored for 20 years.Result shows that the existence of vegetation takes an extremely important role to the microclimate improvement of coal waste piles.The air temperature and soil temperature of coal waste piles,decrease respectively by 2.8℃ and 5.0℃ in growing season,namely,April,July,August,September,compared forested coal waste piles with bare coal waste piles and in October the situation was opposite,increasing respectively by 0.6℃ and 0.4℃.The monthly mean value of air relative humidity increases by 7.1%
