茶园小气候特征及其与相近国家基本站的气候差异性分析

Analysis of Tea Plantation Microclimate Characteristics and Their Climatic Differences from a Nearby National Baseline Station

摘要: 分析凤岗县田坝茶园小气候与绥阳县国家气象站之间的温湿度相关性，建立茶园小气候与国家站间的关系模型，从而为茶叶生产提供精细化的气象服务。根据地区及海拔选择2016年3月至2021年3月凤岗县田坝茶园自动气象站及绥阳县国家气象站逐日平均气温、相对湿度、最高气温、最低气温、日降水量等气象数据，采用对比分析、相关分析及线性回归等方法分析绥阳县国家气象站及凤岗县田坝茶园各项气象要素之间的相关性。凤岗县田坝茶园内的日平均气温、日最高气温、日最低气温均低于绥阳县国家气象站，日平均气温差值在−2.7℃~−9.7℃，茶园内湿度比国家站偏大。两者间日平均气温、日最高气温、日最低气温拟合程度较高，而日平均相对湿度拟合程度较低。逐月来看，凤岗县田坝茶园与绥阳县国家气象站日平均气温在7月拟合程度最好；日相对湿度在6月拟合程度最好。

Abstract: This study analyzes the correlation of temperature and humidity between the microclimate of Tianba Tea Plantation in Fenggang County and the national weather station in Suiyang County, aiming to establish a relational model between the tea plantation’s microclimate and the national station data to provide refined meteorological services for tea production. Based on regional and altitude considerations, daily meteorological data—including average temperature, relative humidity, maximum temperature, minimum temperature, and daily precipitation—from the automatic weather station at Tianba Tea Plantation in Fenggang County and the national weather station in Suiyang County from March 2016 to March 2021 were selected. Methods such as comparative analysis, correlation analysis, and linear regression were used to examine the correlations between various meteorological elements from the two stations. The results show that the daily average temperature, maximum temperature, and minimum temperature at Tianba Tea Plantation in Fenggang County were all lower than those at the national station in Suiyang County, with differences in daily average temperature ranging from −2.7˚C to −9.7˚C. Additionally, humidity in the tea plantation was higher than at the national station. The fitting degree for daily average temperature, maximum temperature, and minimum temperature between the two locations was relatively high, whereas the fitting degree for daily average relative humidity was relatively low. On a monthly basis, the daily average temperature at Tianba Tea Plantation showed the best fit with that of the national station in July, while the daily relative humidity showed the best fit in June.
