为研究龙山县植烟土壤pH时空变异特征与其影响因子,分别于2000与2015年在龙山烟区采集土壤样品191和300个进行土壤pH与各指标的测定,利用描述性统计、地统计学、相关分析、多重比较、逐步回归与等样本平滑回归对该地区土壤pH的时空变异与其影响因子进行了研究。结果表明:从描述统计来看15年间龙山县植烟土壤pH均值由6.32变为6.03,降幅为4.64%,极低(

In order to study the temporal and spatial variability of soil pH and its influencing factors in tobacco-growing areas of Wuling Mountain and provide reliable basis for the regulation of soil pH in tobacco-growing areas,191 and 300 soil samples were collected from Longshan tobacco-growing areas in 2000 and 2015,respectively,for the determination of soil pH and various indicators.Descriptive statistics,geostatistics,correlation analysis,multiple comparisons and gradual regression were used.The temporal and spatial variability of soil pH and its influencing factors in this area were studied by m...
