黄河生态保护对郑州邙山局地小气候的影响

Influence of Ecological Protection of the Yellow River to the Microclimate in Mangshan Area of Zhengzhou

郑州西北部沿黄邙山2008年完成了黄河水土保持生态建设与保护工程,2010年建立生态观测基站并开始对其气象要素进行连续定位观测。利用郑州邙山2010—2020年生态实测数据,运用一元线性拟合、距平法分析黄河生态保护对郑州邙山局地小气候的影响,结果表明:郑州邙山局地小气候变化明显,年均气温、年最高气温、年最低气温、年均空气湿度、年降水量均值分别为15.7℃、40.35℃、-9.15℃、54.53%、406.35 mm,除降水外其他气象要素变化均呈上升趋势;年降水量减小、温度升高、空气湿度增大,说明土壤及地表植被持水、保水功能增强,黄河生态保护改善了郑州邙山局地小气候。

The Yellow River soil and water conservation ecological construction and protection project was completed in 2008 in Mangshan Mountain area along the Yellow River Basin in the northwest of Zhengzhou.Continuous positioning observations of the ecosystem have been conducted since 2010.Using the ecological measured data of Mangshan,Zhengzhou from 2010 to 2020,the impact of ecological protection of the Yellow River on the local microclimate of Mangshan was analyzed by using one⁃variable linear fitting and anomaly method.The results show that in the past 10 years,the microclimate of Mangshan Mountain has changed significantly.The average values of the measured annual air temperature,annual maximum temperature,annual minimum temperature,air humidity and precipitation are 15.7℃,40.35℃,-9.15℃,54.53%and 406.35 mm respectively.Except precipitation,the changes of other climatic factors are on the rise.The decrease in precipitati⁃on,the increase in temperature,the increase in temperature difference and the increase in air humidity indicate that the water⁃retention func⁃tions of soil and surface vegetation are enhanced,and the ecological protection of the Yellow River has played a good role in improving the microclimate of Mangshan,Zhengzhou.
